At least they?ve kept the pickups local :-)
Looks like you?ll have to either deal with the screwholes, or keep the pickup rings if you want to put AXY?s in it?
Hard to see if the Bigsby is original, but I doubt it?
If you use stainless steel strings and abuse the Bigsby, I think you?ll need an open line with the mothership to keep a steady flow of brass saddles. :-)
I don?t know if the strings move much with this system, but most likely the strings will eat up the saddles in no time.
Replacing this with a tailpiece will leave some scars?
Nice bodyshape, the carvings look Alembic style so I bet that is original. Also nice star inlays and an extra switch (Leds?) Only one of the switches looks like the type of switch Alembic uses, could be wrong there though?
Serial number looks like 82D or 82C 21XX (68/88?)
