Usually one of these (replace the sunburst fretless with a Black MIM Jazz in your mind
)
The Black Precision is a '75 and was my first lefthanded bass, traded my Gibson RD Artist for it. This bass is "The One" for me and we have alot of history together. She is semi-retired now as I won't risk loss or damage.
The Vintage White Jazz is my main bass now it is an '83 MIJ '62 RI. The only mods are a BAII bridge and a pearloid pickguard. It has a neck thinner than a Geddy, sounds fantastic!
The Green PJ is a Squier/ Warmoth build. It is an attempt to capture the sound of The '75. Close...but the SD quarter-pounders do not have quite the snarlly bite of the DiMarzios in The '75.
The Sunburst Squier is fretless and heavily modified. I'm still not happy with it's sound. I'll probably put a fretted neck back on it and build a fretless Jazz from a Warmoth maple/maple unlined fretless neck I have. I found having the fretlines and dots on the board to be a real distrraction anyway.
My Black MIM Jazz I often leave at rehearsal. I'm guessing that it is a late '90s early 2000. Got it for prectically free because the neck has issues, but is behaving itself for now. I put an old pair of DiMarzio J pups in it that I had laying around and replaced the bridge with a Gotoh 201 and put a Tort guard on it. As one might imagine, it has a more aggresive tone than the MIJ.
