Well I played one (4 str. fretless) on at a 48th St. store last night after work, just to get an idea. Must say is sounds a little thinner than I was expecting. It was wound with nylon-core bronze strings from Thomastik-Infeld (the guy said they were the factory strings and the internet backs him up); I assume the bass shown above is wound with the same.
I didn't have much time (the store was closed when I walked in) but it certainly seems to be well made and very playable (nice neck). The sound seemed a little thin to me, but maybe I just need to sit down and work with the controls a bit. In retrospect, I should've tried it unplugged; maybe I'll go play the one above tonight.
For 800 it'd be a no-brainer. As it is, buying this would probably put me out of the instrument market for another couple years at least. My Epic is really all I need in the fretted dept., but I've secretly been on the lookout for an Alembic with the low-pass filter.
Maybe the answer is buy this baby and send the Epic back for an upgrade? Not a bad idea...
On another note, the one I tried at the store did not have a thumb rest, and this one does, an absolute must for me.
Anyway, thanks for the input, and I'd appreciate any other contributions.
