My Jazz's.
Squier VM, Changed out the neck with my other VM and defretted it, modified the controls to volume-balance-tone, replaced the stock bridge with a Hipshot bridge and made a new pickguard.
My other VM, put in a set of Hanson Chi-Sonic pickups, modified the controls to volume-balance-tone, replaced the stock bridge with a Hipshot bridge and made a new pickguard.
Richwood Jocker Pro, a "Jazz-ish" bass, very nice bass for its price.
Needed a proper shielding and grounding though, modified the controls to volume-balance-tone, replaced the stock bridge with a Hipshot bridge and made a new pickguard.
My personal tribute to Leo Fender.
I build this one myself, 36/32 inch scale, Delano pickups and Glockenklang 2 band preamp.
