OMG Im so happy to find this thread.
My btb have been in hiatus for 5+ yrs and now that I'm start gigging again, took it out, never had anyone to talk to about this bass (no one around me seems to know much about btb).
Will post some pictures if it when I get home, in the meanwhile, this is the only picture on my phone of her (cavity.. lol

).

Some question on my mind around it:
1. if one to change the neutrick locking thingy, what kind should fit comfortably (same dimension ?)
2. I love NYXLs but pretty hard and expensive to come by where I am now. Would regular slinkys long enough to fit into this long beast ?
@lowfreqman nice setup ! how u liking the audere ?
