i just bought an old peavey XR600C for a really good price, but a few of the knobs on the front of the mixer are completely broken off, down to the washer. the only way to adjust them is to press really hard and turn. any advice on how to get new knobs on? i understand that super glue is not the best choice because of possible damage to the mixer.
You said "knobs"...tee hee.
