I own ten basses of different makes, to include my Spyder and my Europa. I like all of them for different reasons, and I didn't buy them to keep them in a closet. I play them.
Am I more careful with my Alembics? Absolutely. Who wouldn't be given the cost? Does this stop me from gigging with them? Nope. I bought them to play them, like I said. Same goes for my other basses (two Fender Jazz Basses, a Rick 4001, a Gibson Thunderbird, a Gibson Ripper, a Musicman Stingray, a Pedulla MVP, and an Ovation Acoustic Electric). If they were dinged or banged up, sure, I'd be upset. But I'd get over it and keep using them. That's what the Wickershams and the good folks at Alembic made these instruments for. They're both a finely crafted tool and work of art - they should be treated and played as such.
I don't consider myself a collector, even given what I own. They're all basses I've always wanted, but couldn't afford until now. Some I got fairly cheaply (the Ripper and Ovation), others not (the Alembics, the MVP), and the rest somewhere in the middle (Thunderbird, Jazz basses, Musicman, Rick). All of them were meant to be played, and that's what I do with them.
The days of the bass guitar being nothing more than a backing instrument are long gone. It started with guys like Chris Squire, John Paul Jones, Stanley Clarke, Jaco, etc., and now we have guys like Stu Hamm, Les Claypool, and Flea carrying the torch. Those who don't understand that are, IMHO, missing the boat. Back when I first started playing in the mid 70's, slapping and popping wasn't something most guys did. Now it's a required technique for many players. Same goes for sound. The P-Bass and SVT sound isn't the only one out there anymore. The soundman you refer to needs to wake up and smell the coffee.
Anyway, my two cents.

Alan
