My beater began life as an SX SJB-62 fretless before I replaced everything but the original body (i.e. just the wood) and the original neck plate. I replaced everything else on bass, with the vast majority of parts being bought used here on TB over the course of a few years. It was an extremely UN-cost effective a project as you can imagine but unless someone knows what they're looking at most people would never know how heavily modified it is. It's a little heavy and the neck feel is a lot chunkier than a typical Jazz bass neck, but it sounds fantastic and is a real "wolf in sheep's clothing" kind of bass.
I call it my beater even though it's actually in excellent condition rather than in typical "beater" condition.
EDIT: May as well list out the mods:
- Hipshot A bridge
- Nordstrand NJS5 pickups
- WD Music 4-ply tort pickguard
- Audere 4-band preamp
- Ernie Ball Super Lock strap locks
- Hipshot Ultralite tuners
- Fender Deluxe string tree
- Fretted neck from another SJB-62
- Side jack cut into body and jack plate mounted
- Bone nut
- Fender Jazz control plate
- All assembly done by a local luthier/builder
Like I said above, very UN cost-effective! The only parts remaining from the original bass are the body itself (just the wood) and the neck plate.
