Welcome Jonathan: Great pictorial debut!! I like your taste in guitars - particularly the Gibsons and Rics.
Don't let Paul the Bad One talk down your Ibanez bass. I have the 5 string of what I think is the same Ibanez model as yours (also in black). In my case, a semi-abortive attempt to learn to like 5 string. Dollar for dollar, it's actually amazing what Ibanez can build in those factories of theirs. I'd have no problem taking mine anywhere, as long as I was playing through a good rig. And for $160 used off Ebay, it sounds and plays GREAT!! (The seller was a pawnshop - so, I'm sure my bass has a long, sad story, if it could only talk!).
I'm looking forward to hearing more about your custom build. Valentino is a good partner in crime for that sort of thing. Whenever, I've called Valentino with a set of options I'm considering for my bass, I generally wind up taking his suggestion. So far, he's never been wrong.
Actually, it is rather strange that Chicago doesn't have a dealer who could show you a selection of Alembics. Uncle Bob's Music in Milwaukee generally has 3-5 Alembic basses on hand, and occasionally a Skylark. You might give them a call if you were interested and able to get up this way.
Anyway, welcome and don't be a stranger.
Bill
