I bought a John Petrucci 7 in red pearl burst from eBay and when i first got it, it was fantastic. It is one of the earlier models from when they first came out (circa 2001?). I can tell based on the fact that it does not have the shield inlays and is very similar to my buddy's jp6 of the same vintage. Anyway, when I first got it the piezo worked fine except for deep dive bombs when the low b would cut out. After I changed the strings and tuned it back up, the piezo only comes out at an extremely low volume. I have changed the battery, but I am thinking it is a problem with the transistor(?) Has anyone else had this problem and fixed it. I am considering sending it to SLO but that seems very expensive and I am pretty handy with guitar electronics and I believe I can change the broken piece myself. Anyone have any advise?
