I bought this one :-)
Dave, you're right; one of the switches isn't right. I think it should be a 3-position bass cut/straight/boost, but it seems to be just a straight/boost 2-position switch.
Also, the wiring on the Q-switch seems a bit odd; the switch appears to be a single-pole double-throw, but the centre lug has no electrical connection to it! (and toggling it makes no discernible difference) Looks like someone has had some fun electrically with this guitar in the past. I'd like to get it back to standard :-)
I'll start getting busy with my camera, and I hope that the Alembic chaps can supply a replacement switch and some details of the standard wiring once we've figured out what's going on.
The rest of the guitar seems largely ok. A couple of the brass inserts which the backplate screws screw into have pulled loose, so does anyone have advice on the best way to reattach them?
Also, the brass tail looks like it is laquered, but this has worn over time, and it looks like there is a little surface corrosion creeping in underneath. Maybe I should leave it, or maybe disassemble and clean-up.. Any advice?
So many questions..
BTW, I think the serial is 82D2131, but that's just from memory.
