I ordered a BBE Crusher to get a more natural sounding distortion opposed to my Digitech Death Metal. (Using a Peavey Sheffield 112) The pedal overall is great, nice tone for a reasonable price but if it had a tad more output (For really crunchy palm mutes) it would be perfect.....Any mods for such a thing?
I didn't find any schematics, but I'm sure it uses the same components as most other pedals. Read up about the circuits in the pedal building thread. https://www.ultimate-guitar.com/forum/showthread.php?t=630592&highlight=pedal+building+thread
