OH MY gOD!!!!! Got my J-Retro preamp yesterday, installed it today, tommorrow - THE WORLD!! I know I'm a late comer to this party but I've just got to say what a killer piece of hardware this is. It is everything it's advertised to be and maybe just a little bit more. I'm in love all over again with my main instrument. The eyes of the smiley faces don't bug out far enough and the jaws aren't hanging low enough to use in this post. I think the J-Retro was about the only thing left to change on this bass and I certainly saved the best for last. Here's a description of it as it is now: 1989 Fender MIJITSO '62 Jazz Re-Issue in black - Twin sister to it's fretless 1996 version - chrome J-Retro, Seymour Duncan Basslines pups, black Schaller roller bridge, charcoal MOP pickguard, black Gotoh reverse Kluson style tuners, black string retainer, and black Schaller straplocks. Oh yes, the most important part: A musical imbecile behind the neck! Now I've got to get one of these baby's for the fretless and, though I won't be mistaken for a talented musician, folks will know I can pick out the hardware.
