I think I've probably posted about my 'Bass of Theseus' elsewhere, but I don't think it has graced this 'bitsa' thread.
This started out about 25 years ago as a fretless I put together using a neck & body from brandoni guitars. It wasn't getting played, so last year I bought a bunch of bits & bobs and rebuilt it.
The parts used in this incarnation:
Brandoni Japanese body (identical to the MIJ '62 reissue I used to own)
AliExpress aged pearl pickguard
Fender pickguard screws
Fender thumbrest
EMJ 'Geezer Butler' P bass pickup & loom
Puretone output socket to replace the one that came with the EMG
Amazon anti-slug tape
Fender P to J conversion neck — The neck came fitted with a nut which was subsequently slotted & shaped to perfection by John at the Gallery
Hipshot lollipop HB10 tuners & bushings
Fender 'Badass style' HiMass bridge with brass saddles
Gotoh nickel plated string tree & strap buttons
Callaghan heavy knurled machined knobs
Ernie Ball 40-95 Cobalt flatwounds
Its almost a shame that I love gigging with my JMJ mustangs so much as this really should be getting some action.
