Cracks on high gain on guitar knob

Pisound Support
1

Hi, when I finaly tried to play in concert with my pisound based guitar multieffect (KleagMFX Documentation), I discovered that when the gain knob of my guitar is pushed too far, there is a lot of terrible cracks and noises, that do not sound at all like a saturation effect, even with a clean sound. And in fact, the input led of the pisound turns red very early when turning the knob.

How could I solve the problem ? It is not great to have to keep the gain in the lower half. I suppose there can be a lot of reasons, but I don’t know where to start.

Does it happen in your regular environment of using the multieffect box? I would initially suspect the power supply and wiring - some cables could pick up external electrical noise (like 60Hz hum) that could cause issues like that.

Ideally, you should aim to keep the Pisound’s input gain knob set to the lowest possible level, while turning up the output volume of the device providing the input signal, so that when you play the loudest, the clip LED on Pisound won’t turn on.
