Peterson Tuners and Metronomes


From Wilhelmshaven, Germany

challenging, yet inspirational sound devices

JPTR FX was founded by enigmatic sound enthusiast Chris Jupiter in 2015, with an aim to create devices that are musically expressive, intuitive and still present very challenging tones through devices that value creativity and spontaneity above all.

Although Chris only opened his pedal workshop in Wilhelmshaven, Germany just a few years ago, he and his team of mad scientists and musicians already have managed to make an impressive impact on the pedal scene with their extremely creative creations. A gritty but stylish monochrome look grace the outside of the pedals, while the insides bubble with colourful, unique and totally inspiring sounds.

From the warm and vintage-inspired dual echoes of the FERNWEH, the grinding reverberating chasms of the KALEIDOSCOPE, the creative potential of the DRUMTHING DELUXE and FEEDBACK F, the sizzling lo-fi tape modulation of the ROYGBIV and all the way to the wealth of inspiring dirt tones found in their TESLA WOLF, SILVERMACHINE, GAINSAW and JIVE pedals, JPTR FX are sure to set the sonic imagination of ambient adventurers, noise-seekers, shoegazers, metal heads and fiery fuzz fiends alight.


Vintage-Voiced Dual Delay Pedal

in today’s arena of delay effects, the longing for a far travelling, expansive sound and the thrill of uncharted spaces dictate the game. The FERNWEH – Multi Echo Module is the time-bending answer from JPTR FX to exactly those needs, seeing multiple switchable delays move you and your sound from your quaint earthly realms and into the sonic unknown.

This expansive delay is more than a temporal effects pedal. It is a trampoline between the unsophisticated and habitual, or the wondrous and the uncommon. Its fast response and dynamic range make it a perfect live tool for haunting sceneries and frenetic solos. The FERNWEH (Wanderlust in German) is, without a doubt, a delay pedal that wants to take you places.

  • Vintage-voiced Dual Delay – from classic rhythmic tape-like echoes to otherworldly cascading dreamscapes

  • Warp Switch – instantly jump between two different delay times

  • Feedback Switch – hold to momentarily max out feedback, for walls of rolling ambience

  • FX Loop – allows you to add other pedals internally that helps to create and expand upon your very own delay tones 

  • Powered by regular 9 V DC PSU (9V DC, centre -, 2.1mm, <80mA current draw)

The FERNWEH operates as two stacked delays that can be controlled separately, to cover your sound in a soft, atmospheric haze. This unique design allows the player to configure different time settings between the two delays, which can often result in elaborate rhythmic patterns or reverberating textures, followed by a lush trail. 

In addition, FERNWEH sports a momentary switch for infinite self-oscillation and another switch to warp between time settings, switching from time A to B repeatedly. Set the time settings further apart for a rich, textured delay warping into a drenched, glistening reverb. Turn both times up and swap back and forth between the launch into space and the shattering descent back into orbit. Throughout all of this, the FERNWEH’s core sound always remains soft and familiarly vintage.

While the two delay signals are always running into each other, you can easily isolate either delay simply by turning down one of the mixes, and voilà – a straightforward delay. However, for those of you who find yourselves looking to further push the limits of the FERNWEH, we suggest dimming the mix knob. A light boost will be engaged with the mix turned all the way up, adding some extra dirt for your sonic extravaganza. Couple this with an expression input for both feedback and delay time and the FERNWEH can be in your complete time-travelling control. 

This beautifully crafted and bizarre vintage style delay is hand-built with tender love and care and prepared to weird up your sound.


Textural Reverb Pedal

If you are the kind of earth-dweller who loves to drench their chords in ambient infinitude, drown their fuzzes in a ceramic cave or even just subtly coat your rhythmic playing in a liquid swirl of overtones, then the KALEIDOSCOPE is exactly the reverb pedal that you’ve been searching for.

With a medley of reflective possibilities at each turn of a knob, KALEIDOSCOPE is a breath of fresh air to add to the end of any pedal chain. In fact, the only downside might be that your signal chain may never sound as exciting when it’s turned off!

  • Textural Reverbs – from subtle spring-like tones, to vast ambient soundscapes and anywhere in between
  • Compression Dial – add everything from subtle presence, to walls of distorted reverb
  • Hold Switch – momentarily increases reverb feedback, for sustaining ethereal textures
  • Kill-Dry Switch – instantly disappear into a pool of ambience by removing your dry signal with a single press
  • Powered by regular 9 V DC PSU (centre -, 2.1mm, ~159mA current draw) 

However, this isn’t just any ordinary big reverb in a pedal. Like its optical namesake, the KALEIDOSCOPE reflects your signal, be it once or more, each duplicate meshing together harmoniously while adding compression, modulation and copious amounts of feedback frenzy to your signal.

A pedal’s musicality is fundamental at JPTR FX. So, whether you use the pedal with your guitar, bass, drums, synths or even vocals to further explore the cavernous and layered reflective depths within, the KALEIDOSCOPE was designed to complement and adapt to all manner of musical styles and input signals.

Roll back the reverb and dime the feedback control for lush, rhythmic wobbles that twist and gyrate along to your sound-beds or turn everything up for a saturated, sustained sound. The Compression Dial comes right after the reverb, which really helps to really push your tails – as the reverb fades out, the compression pulls it back up to helping to elevate your seat in the mix. At the same time, 3 separate control stages offer you instant shifts in depth, texture and oscillation, ranging from the warm and haunting cloudscapes we have come to love, to an all-wet, crispy whisper with the help of the designated Kill-Dry Switch.

Plus – and if the mood strikes – push and hold the momentary switch at the heart of the KALEIDOSCOPE ‘s enclosure to extend your drones into perpetuity.


Fuzz Modulator Pedal

JPTR FX truly outdid themselves on their weirdness with this transcending fuzz modulator. Now it’s up to you to outdo yours! The SUPER WEIRDO will be your closest friend and best kept secret, the kink in your playing and the twist in your tone.

A testament to its name, the SUPER WEIRDO is unearthly, alien and downright trippy and possibly is the only pedal that simultaneously builds monumental walls, all while tearing them apart at the same time!

  • Fuzz Modulator – from classic, thick gated fuzz tones, to glitchy sonic anomalies
  • Pulse Width Dials – create everything from huge doubler tones, to chaotic cascading walls of sound
  • Glitch Switch – momentarily introduce oscillation into the signal, for bursts of trippy textures
  • Expression Input – for on the fly control of the delay time Highly tweakable fuzz pedal – endless worlds of fuzz at your disposal
  • Powered by 9V DC PSU (9V DC, centre -, 2.1mm, ~80mA current draw)

On the surface, the SUPER WEIRDO is disguised as an early 90s-style gated fuzz, with a dedicated low pass filter knob to effortlessly find your place anywhere in the mix. But that’s far from where the freak show ends. This three-headed beast delivers fuzz, time modulation AND momentary glitch-bombs all in one enclosure.

The core operation of this unit is to further enhance the input signal with an advanced, time-based modulation effect – The Pulse Width Modulator.

Two dedicated knobs allow the player to multiply and manipulate their playing. The Feedback Mix controls the amount of modulated signal added to the base sound, acting almost as a doubler. A further Time Amount knob controls the distance between each modulated pulse, enabling the addition and separation of layer upon layer, resulting in a wall of thick, dynamic and articulate fuzz. Plus, if you dial in a short time setting, you get a doubletracking fuzz tone.

Beyond this, an extra momentary footswitch gives the player expressive freedom to disrupt the signal with quick bursts of oscillation – aptly named Glitch. Plus, to guarantee all manner of expressive possibilities, an expression input allows you to connect a standard expression pedal for on the fly creativity.


Lo-fi Modulation Pedal

As colourful as a full spectrum rainbow and just as variable, ROYGBIV embodies the JPTR FX philosophy of musically expressive pedals that demand your manipulation. This is JPTR FX’s take on the driving sound behind Boards of Canada, along with a grateful nod to the 80s and the legendary Juno and Dimension Chorus units, fused with an itch for noise and frequency shifts. We are proud to introduce you to our VHS colour vision. 

This unique modulation pedal sports classic depth and speed parameters, which are further complemented with noise, frequency and grind controls, all giving you complete sonic freedom between Lo-Fi tape saturation and classy glassy warbles. The pedal that’s equally for those that have never liked chorus and also for those that do, ROYGBIV (Red Orange Yellow Green Blue Indigo and Violet) adds true colour to your sound!

  • Lo-fi Modulation – from classic dimensional chorus to mangled lo-fi tape tones
  • Speed-Ramp Switch – instantly go from slow warbles to Leslie-like spins
  • Grind Control – from a touch of tape-like saturation to full-on fuzz fest
  • Noise Control – introduce everything from subtle tape hiss to waves of white noise
  • Filter Control – make the modulation modern and pristine or warm and vintage
  • Wet/Dry outputs – get huge and wide chorus tones when using two amps
  • Powered by 9V DC PSU (centre -, 2.1mm, <120mA current draw) 

Based on a classic yet unorthodox take on a dual “Dimension” chorus using PT2399 chips, ROYGBIV, the apply dubbed “Tape Quality Manipulator”, contains a great range of modulated textures via its simple yet unconventional control set, replicating all manners of tonal colouring of a vintage VHS machine.

The familiar Depth and Rate controls will take you from shallow shimmers and subtle widening, all the way to deep mesmerising chorus tones and fast Leslie-like spins. Whereas the non-traditional Grind, Noise and Filter controls will help introduce everything from sweet saturation, nostalgia-filled currents of subtle tape hiss and warm vintage tone roll-offs, all the way to relentless distortion attacks and smothering layers of white noise. This makes the ROYGBIV perfect for both conventional chorus use, as well as experimental lo-fi tone trips and is a great tool for faux doubletracking too.

To further enhance the already impressive range of creative uses with this pedal, JPTR FX also includes a momentary Speed Ramp switch, which instantly maxes out the speed of the modulation, seeing you jump between two different modulation sounds in seconds flat. Plus, with the addition of both a Dry and a Wet output, the ROYGBIV will give you epically huge chorus tones when using a stereo setup.

As with all JPTR FX creations, this pedal shines just as well outside of its element as within, delivering the finishing touch for keys, bass and vocalists alike. Once again, JPTR FX embraces the spontaneity with the additional foot switch that kicks the speed parameter to maximum, for instant Leslie rotations.


Reel Saturator Pedal

Inspired by an old Akai GX 210D reel to reel tape machine from the 1970s, the JIVE – Reel Saturator was made to give you the gooey and warm saturation obtained when pushing the Akai’s pre-amps to the max.

This pedal is bold, gritty, present and simply chock-full of screaming old-school mojo. If you are into lo-fi garage tones, want to make your modern-day synth sound like 1972 or if you simply want to add a touch of vintage warmth and presence to your guitar/bass/vocals/whatever, then the JIVE – Reel Saturator is your sonic dream come true.

  • Lo-fi Reel Saturator – from subtle tone enhancing, to mind-melting distortion
  • Volume and Gain – for ample amounts of dB on tap
  • 3 clipping diode selectors – mix and match diodes as you like, for ceaseless saturation combinations
  • 9V to 18V operation – allows for increased headroom
  • Powered by 9V DC PSU (9V DC, centre -, 2.1mm, <50mA current draw)

The JIVE’s control set is supremely simple, yet staggeringly versatile. Familiar Volume and Gain controls make things louder and dirtier as expected, but what truly gives the Jive character is its three clipping diode toggles on the right-hand-side of the pedal.

The top toggle introduces an Asymmetrical Germanium diode, the middle inserts a Symmetrical Anti-parallel Silicone diode, while the bottom toggle presents a Symmetrical Anti-Parallel Germanium diode. You can mix and match all of these diodes as you please, for worlds of different dirt flavours.

Use JIVE as a volume boost, a subtle compressor or even a semi-transparent overdrive, exalt your sound with variable distortion or tear some walls down with lots and LOTS of dB. It is all up to you.

You can even run this mojo monster on everything from 9v to 18v giving you even more headroom to explore the crackling and gritty textures within the JIVE.


Dual-gain-stage Fuzz Pedal

Iconic sounds are often a product of struggle and compromise. They are unmistakable, genuine and have the potential to leave a mark on society. They are bold, out of place and larger than life. They fight back, claim their prize but never abandon their humble beginnings.

They are the SILVERMACHINE – Dual Gain Stage Fuzz!

  • Dual-gain-stage Fuzz – from low-gain sizzle, to beefy Bender tones and all the way to screaming octa-fuzz sounds
  • Two Gain knobs – acts as two highly interactive gain filters for endless fuzzy combinations
  • Master Volume – we all know louder is better!
  • Eye-catching vintage enclosure
  • Powered by 9V DC PSU (centre -, 2.1mm, <50mA current draw) 

SILVERMACHINE is a new interpretation of a time-tested attitude. Featuring two gain stages in a parallel circuit, competing for an unrefined and unbuffered vintage fuzz conquest. With one shared master volume to keep it simple but never stupid, the SILVERMACHINE´s gain knobs act as a filter, delivering tones that range from sizzling drives to rich, dynamic fuzz.

Pushing the gain stages even further brings out the upper octave, instantly reminiscent of the wild Woodstock days, with a twist of Beatnik club nights and Lo-Fi Psychedelic Garage seances.

The SILVERMACHINE retells Fuzz history in a modern iteration. Its versatility carries tones between Benders and Faces, but infinitely less compressed and deliberately open in character.

A first in less aggressive gain spectrums for JPTR FX, and definitely the most versatile. Its humble looks may be deceiving, for this spacecraft can take you anywhere – past, future and present alike.


Ultra-versatile Overdrive Pedal

The TESLA WOLF overdrive pedal is the quintessential low gain paragon that started it all for JPTR FX. In an understated and classical style, it’s modus operandi is very simple – kick it on and rip it out.

Consequently, the TESLA WOLF is more than just another overdrive. Stripped, bare and convenient, it covers the most ground in both late and modern overdrive history, ranging anywhere from the early Kinks stabbed speakers, to modern and tight and everything in between. 

  • Multiple drive options – from subtle low-gain drive to fire-breathing fuzz
  • Voltage Sag Control – emulates a slowly dying battery for unique sputtery dirt tones
  • Internal DIP Switches – changes the tonal characteristic of the pedal, for 4 drive pedals in one
  • Powered by 9V DC PSU (9V DC, centre -, 2.1mm, <50mA current draw)

TESLA WOLF’s simple controls allow for clear-cut and straight forward execution. A master volume, gain structure, low pass filter and a voltage choke shape its remarkably versatile base sound, which can go anywhere from soft clipping and a subtle push to a full concussion received at a stoner-doom gig where the stacks come tumbling down.

You can actually easily go from both ends of the dirt domains simply by varying your dynamics, since TESLA WOLF is one of the most dynamic and touch-sensitive drive pedals currently on the market. Just pile on the gain and let your picking attack decide whether you’re whispering or screaming at the crowd.

Meanwhile, the voltage choke allows you to get that dying 9V sweltering fizzle, just without having to assault mother nature with evil batteries. It has a controllable range from a stabbed speaker (3 o’clock) to a sustain killing broken radio (noon) and glitchy little octave sputtering (<12 o'clock).

Like with all things, it is the beast which is out of sight that is the most terrifying. As such, we have expanded TESLA WOLF with additional internal DIP-switches to further fine tune your gain structure and base orientation, essentially turning this single pedal to four individual overdrive pedals in one housing.

Switch one activates two silicon diodes, while switch two introduces two military grade (and over 3 decades old) germanium diodes, for a tight, tube like sound and classic, vintage-inspired fuzz clipping. The third dip switch gives the base orientation a tight & tidy smack – familiar from the old rodent-inspired gadgets from the late 70s – by adding two pairs of LEDs to the circuit.

The fun with combining all classically sought-after clipping diodes in one housing doesn’t end there though.

Turning all of them on or combining them, reveals this humble overdrive to be a behemoth of gain possibilities. Conveniently, we have left a hole in the back for easy, tool free and gig-friendly access too, so you can change your tone on the fly.


One Knob Fuzz Pedal

The one, the JPTR FX cult classic and the figurative full-on storm in a teacup, the GAINSAW is all its name suggests and then some. Sounding like the engines of two colliding trucks, while keeping all manner of feedback at bay, it’s big open tone, massive gain reserves and bizarre low-end harmonics will, quite indisputably, blow you away!

Gut churning and unforgiving, GAINSAW delivers bright, wide and open sounding fuzz with a simple, single knob circuit. Just set it, forget it and begin your onslaught of devastating riffs!

  • Dirt-simple dirt device – one knob determines the destructive distortion power within
  • Cutting character – bring presence and bite to deeply drop-tuned instruments or dark amps
  • Control at your fingertips – use your instrument’s volume knob to yield different distorted textures
  • Internal DIP Switches – changes the tonal characteristic of the pedal, 4 pedals in one!
  • Powered by 9V DC PSU (centre -, 2.1 mm, <50 mA current draw) 

A gated distortion at heart, the GAINSAW works perfectly with your volume pot and playing dynamics, placing its tonal range anywhere between Satisfaction by The Rolling Stones to Siamese by The Smashing Pumpkins. It is undoubtedly the loudest pedal you will ever hear, but also equally effective whisper quiet.

With its single volume knob, this allows ease of use and intuitive playing, keeping all the clarity intact despite gargantuan levels of gain. Perfect for low tunings, GAINSAW also sounds remarkable when boosted – although it is highly doubtful one would need more gain to be honest!

Like with all things, it is the beast which is out of sight that is the most terrifying. As such, we have expanded GAINSAW with additional internal DIP-switches to further fine tune your gain structure and base orientation, essentially turning this single pedal to four individual fuzz pedals in one housing.

Switch one activates two silicon diodes, while switch two introduces two military grade (and over 3 decades old) germanium diodes, for a tight, tube like sound and classic, vintage-inspired fuzz clipping. The third dip switch gives the base orientation a tight & tidy smack – familiar from the old rodent-inspired gadgets from the late 70s – by adding two pairs of LEDs to the circuit.

So, despite the single knob on the top, this diminutive device can grow with you. It may be one style of dirt pedal now, but if you want to get a different style of drive in years to come, GAINSAW has got you covered!


Piezo Spring Preamp Pedal

One of the most creative and curious JPTR FX creations is without a doubt the DRUMTHING DELUXE. Inspired by many guitarists in the 1990s who attached Piezo pickups to their tremolo cavities to produce percussive and alien sounds, JPTR FX embarked upon a design that could incorporate these musical, intuitive and bizarre instrumental tones, but in pedal form.

If you’re looking to bring some splash, crash and clang into your creative workflow, then this crazy little critter should do the trick!

  • Spring-equipped percussion instrument – from subtle clangy beats to a full-on industrial frenzy
  • Built-in Piezo Mic – for capturing unique resonating textures
  • Get creative – use on its own or use it with other pedals, for bold rhythmic textures
  • Powered by 9V DC PSU (9V DC, centre -, 2.1 mm, <50 mA current draw)

The DRUMTHING DELUXE consists of three vital components: Springs + a Piezo microphone + an overdriveable preamp. Why? Just because! On first glance, it is a simple yet percussive little box that adds the sounds of springs to your signal. Pluck them, strum them, flick them, stomp, kick and curse at them, perhaps even in a foreign language. Play them with a violin bow, an e-bow or a real bow if you’ve got one, you wild tone-hunter. There really are no rules!

On face value, the DRUMTHING DELUXE can easily be underestimated due to its rather seemingly simple functionality. But by taking into consideration that this box will react to its surroundings, just like any microphone would, you’re in for a wild sonic ride. For example, placing it on top of your amp will immediately incorporate the amp’s own vibration, translated through the overtones produced by the springs.

For even more possibilities, you can change the springs, remove or modify them outside its percussive element. Remove the springs entirely and you have a piezo mic in a box, which you could Velcro on to any surface, instrument or flooring to capture deep, overlooked sounds in any venue, studio or even inside a bass drum.

The DRUMTHING DELUXE is many a thing, but certainly beyond being summarised in just a few sentences. It is as simple as a resonator guitar for your pedalboard or a stomp tool while playing country at a club. It could be also be as complex as your entire industrial percussion section or a means to record and capture the un-recordable.

Turn your surroundings and everything within them into instruments of their own.


Feedback Looper Pedal

It’s no secret that JPTR FX has a soft spot for noise. Through multiple delirious adventures within the boundaries of all things sonically captivating and conceivable, nothing represents the JPTR FX philosophy as simply and honestly as the humble FEEDBACK F and its infinite oscillating noise potential.

If you have ever held the frivolous belief of ever buying that ‘final’ pedal, then this humble device is just the thing. It will scramble delays, reverse wahs, sharpen filters, rev up distortions and generally just take your pedal collection to places you never thought imaginable. Regardless of what you anticipated, you will appreciate every happy accident its journey brings your way!

  • Extra-simple dirt device – one knob determines the destructive distortion power within
  • Create new worlds of sounds with the pedals you already have
  • Feedback Control – from subtle side effects to chaotic ear-ripping cascades
  • Compact design – there’s no excuse not to add some extra sonic spice into your life
  • 100% Passive circuit (no PSU required)

A passive feedback looper with a single pot to control the feedback intensity, FEEDBACK F’s application may at first seem somewhat predictable, due to its very nature. While that may very well be the case for some, for others this pedal will be the figurative ‘box of chocolates’ filled to the brim with new ideas, discoveries and excesses.

Yes, this pedal is beyond just being simple to use, but contrarily it has the means to produce the most complex audible responses and transform any individual, assembly or cluster of pedals into a right mess of awesomeness. A whole new thing you can do with what you already had lying around, that’s just one thing that FEEDBACK F can do!

Another neat trick is adding an old 3-head reel-to-reel or cassette recorder to the FEEDBACK F loop, in record and monitor mode. With the right model and experimentation, you’ve got yourself got a DIY space echo or tape delay. The tape speed will set the delay time and feedback will be controllable on the FEEDBACK F – it’s that simple!

While JPTR FX have many recommendations for how to use this pedal, sharing more of them would undermine its core purpose of experimentation, discovery and fun. In fact, our only real recommendation is for you to take your time with it – ‘Bob Ross’ it even. Add one dirt pedal here, a happy little modulation pedal there, perhaps even switch around the order of your pedals, add a bit more feedback and voilà!

Audio Distribution Group is proud to be the UK and European distributor for JPTR FX.
