I have 4 basses: an MIJ fretless Jazz Bass, a Reverend Rumblefish XL, a Hamer 2-TEK CruiseBass and an inexpensive P-Bass clone. I love all of them but lately the P-Bass clone has been getting the lion's share of stage use. It is basically a parts bass I bought to use as a beater. It has a mahogany body and an "Original '62" pickup. When I bought it, it had a maple neck with a maple board, 1 5/8" width at the nut. I replaced that neck with one I bought off e-Bay for about $25 (!) that has a 1 3/4" wide nut that looks like an MIJ Fender P-Bass neck. The neck pocket is wider than the neck by ~1/16" and I had to shim it to get the action where I wanted it. By all accounts it shouldn't sound good...but it does and it sustains like crazy. Musicians in the audience, my bandmates and sound techs have all commented to me about its fat sound. The other basses are all "better" by any objective standard but I just grin every time I pick it up. Maybe it's because I did so much work on it, but it has become my favorite. Does anybody else have a "mutt" or "beater" that they use more than their "good" basses?
