I've been working on this project for about a year now. The inspiration came after getting the fretless, loving it (my first Jazz) and wanting another to complement. Obviously the first two are the relatives! The fretted is a 1989 MIJITSO '62 Jazz. Upgrades are Gotoh reverse tuners, Schaller bridge, Fender PG, and chrome knobs. This bass will soon have a J-Retro preamp! The fretless is a 1996 MIJITSO '62 Jazz. It came with the ABM bridge, and MOP pickguard. I added the Fender tuners, brass nut, chrome knobs, and dyed the fingerboard. I swear that it has aftermarket pups in it but can't be sure. They sure do sound hot though. So which is the EVIL TWIN?
