I have a Jazzmaster I put together for myself a few years back from a Fender Japanese model that had a horrible repaint job and a Strat neck. I ended up repainting and changing out everything on the guitar except the body by the time I was done with it. Because of it's Frankenstein status I don't have any misgivings about getting weird with it & have been considering adding a middle pickup to bring more versatility. Ideally something that would not require routing would be nice, but I have access to routing equipment if I decide to go that route. I was thinking of something along the lines of a Goldfoil-type. Has anyone done this with a Jazzmaster and have suggestions on pickups that might work well? The guitar currently has Curtis Novaks, JM-FAT in the bridge and a JM-V in the neck.
