What the heck, I emailed Kustom a couple days ago and they said they can't sell the schematics. I even asked a shop that repairs Kustom amps. Lower value, mmk got it. Thanks!

Alright well I think I might toy around with it sometime soon. Does anyone know What value resistors usually give more gain? I'm not sure what values are in right now but Ill check later, had a long day and it's time to rest.

Oh sorry, CLick to enlarge.

Pictures will be in shortly.

Just so theres no confusion the control layout is like this looking from the angle taken in the pictures.

Thanks for replying! I've tried looking for schematics before and I tried again this week and still have found nothing. I'll take pictures of the board when I get home today. The thing is I really don't want to use an effects pedal, I just want a straight into amp setup. If all fails then that will be my last resort. Thanks a bunch.

Hey there everyone, I own a solid state amp (Kustom quad100), I want more gain/distortion. It only sounds decent at higher volumes but at low volumes its really crappy for dirty sounds. Can I replace something like diodes/resistors to get more gain? I just need to know what to replace. I have decent enough soldering skills and to do this I think, I just don't know what to change. Enlighten me, please!

Theres a "gain" knob so it should control something, but what is that something? The pot is a 100k pot for the gain knob if that matters. and it says VR1 next to it on the board. Also a "boost" switch that boosts the gain a bit.
