Folks: I'm in the market for a new bass, and I swung by a neighborhood pawn shop. They had a (very) used Fender JP-90 with no price tag. The previous owner had yanked the frets from the rosewood fretboard and had sanded the front and the back of the body, leaving some paint on the inside surface of the cutaways. The thing is kind of a mess... the volume dial turns and turns without stopping, the J pickup hums a lot, the neck's finish is very worn in places, and it looks likes it's been mistreated. Also, the neck bolt plate doesn't say "Fender" on it - it's just a blank metal plate. Finally, the bridge looks totally econo. Added up, these make me wonder if some guy just bolted a Fender neck from a dead instrument onto a knockoff body. I had a friend that was a victim of this before. I might just offer a couple of hundred bucks and walk with it, but not if it's a fake. Any way to tell for sure?
