I know several people who are very happy with their VMJM. I don't know anyone with the J. Mascis (though I lust after the purple sparkle -- which color did you get?). Does anyone know if they're made in different places or anything? It does sound like you got one off the lemon tree. Even cheap tuners shouldn't have that sort of problem. As for the VM Jag, I have one and I like it a lot. Maybe I got a good one. Yes, the rocking bridge is loads of fun to set up, but once it is it ought to be fine. I haven't had any electronic problems. I went into that with my eyes open, though. I wanted something close to an original style Jaguar, which the modern player isn't. And it was inexpensive enough to take a chance. I figured that even if I had to swap out everything except the body and neck, I'd be ahead.
