Greetings, I'm about ready to pull the trigger on a 1993 Peavey bass amp. The treble tone pot is completely broken off, but the rest of the amp is nearly pristine. I'm not very mechanically inclined, but if I could get this little gem fixed, it would be a nice little practice amp. Can someone please help -- explain how I would replace the treble pot and how do I know what to buy? I don't even know where I'd get one. Thanks!
