I have a KPA and I'm experiencing some problems with my setup. With passive pickups my tone sounds killer, but when I plug in a guitar with active pickups it's sounding really dull. The strange thing is, it seems to be losing gain even though the pickups should be more 'hot'.
I've tried the obvious things; change the battery, made sure the input is not orange/red, tried changing some stuff about the tone itself, tried other guitars, other cables but the problem keeps persisting4.
After some research I found out about Clean Sense but even with that it still sounds dull.
If anyone has suggestions, ill be as active as can be.
