It’s no secret that over the past few years stereo pedals have become a huge part of many musician’s rigs. While many regular tones can (and should) be mono, we at KMA love stereo effects (we actually have quite a few of our own in development right now), but why is it so hard to use them either at home or on the stage? Without the luxury of 2 amps (plus the ability to turn them up if you have them) or for owners of cab/amp simulators that are usually mono input by design, monitoring stereo effects properly can end up being so difficult that many just end up running their stereo effects in mono and therefore lose many of their spatial creativity nuances.

Doubling guitars in recording is also a common practice in a variety of musical styles. In many cases, a single guitarist will record the same track twice with each separate recording being spread to the left and right channels. The effect of this is unmistakable to the ear and the slight differences and nuances between the two separate performances complement each other to create a noticeable thickness, density and weight to the musical experience.

This is hard to get sounding right live too. Note this is not the same thing as simple doublers (that just delay one signal with a modulation) or ADT type solutions that are on the market today.

So, KMA developed ENDGAME. We wanted to make an easy to use product that gives the essentials of good tone, nothing more and nothing less. While from the front panel it might look like ENDGAME has lots of controls, compared to many hidden menus and screens in many other products, all means that it is also deceptively simple to use, despite the huge complexity of what’s going on inside!
