Just found a Peavey MP400 in the trash this week and overall it's in pretty good shape! Only issue is when I turn the master reverb knob up, it produces a loooot of buzz that grows louder as the knob is turned up. While there is a buzz, the reverb still functions properly. Wondering if this is an easy fix—I'm pretty useless when it comes to electronic repairs. Otherwise I'll just send out to a reverb pedal and return through the AUX—would be nice to have the onboard verb sans buzz though!
Thanks in advance!
