Tim,
You're in Santa Rosa, right? I suggest that you pay the folks at Alembic a visit..... I can't think of a better place to get Alembic advice...
BTW, the bass is very nice indeed, but what I've come to understand is the instrument is only worth what you're willing to pay for it. That being the case, the resale value is only worth what someone who is in the market and has the dollars is willing to spend.... What I'm saying is; The value is very subjective.... I don't plan on selling my Alembic, and if I am fortunate enough to aquire another along the way... they will go to family members after I'm outa here.
Give Alembic a call.....Hell, if I lived in Santa Rosa, I'd be camped out in the Alembic Parking lot.......... Lucky for all involved I'm in Washington State!! LOL
