My bass knob doesnt work properly anymore. Ive been searching for a while on Ebay and all sorts of stores on the internet and cant seem to find a bass knob that i know will work for my amp. Its a Crunch amp powered by Maxonics. Its 1600W mono channel. Gpr-1 is written on the face of the bass knob, so i guess thats the model of the amp or the bass knob. If anyone can tell me where i can find that bass knob or any compatable bass knob that works with my amp, it would be much appreciated!!!
