Just looked at this listing again as i am strangely attracted to this train wreck:
https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2380057.m570.l1312&_nkw=alembic&_sacat=3858i was pretty sure the original listing included the F2-B, that verbiage seems to be missing from the re-list. makes me say hmmmm...
if it was the whole schmeer for about $1500 less than it is now, i'd be thinking winter 2021 project while we're locked down for the next pandemic. i'm pretty handy with a soldering iron and a schematic, been inside of plenty of amps and an F2-B or 2 back in the day so that doesn't scare me. if they had no qualms about hacking up the bass electronics, i'd guess the F2-B mods probably go further than the garish knob job.
hard to say if it's a long scale. i'm thinking probably more likely 32" but it's hard to tell from the picture and the seller seems to think it's a 6-string, so that's no help. of course, no serial number.
oh well - back to the grindstone. some land mines are best left un-stepped-upon...
