My two main basses are my Maruszczyk Frog and a Warmoth 3-pickup jazz (currently in my avatar). Both of those basses have been to nice venues, festivals, and dives. I do understand the mentality of not wanting to take an expensive bass to a dive, but for the purposes of protecting one's investment. I don't understand the mentality of being wary of what bass to play because of concern about drawing attention away from the show. I don't get that. I suppose if I had Bootsy Collins' 5-pickup star bass in my collection, it might be a legitimate concern, but only because it wouldn't really fit any show I do. Anything else, my thinking is that the bass I play is part of the show, and therefore nicer is better in most situations.
While it's not exactly my cup of tea, the configurator picture you posted above is a beautiful instrument. And if I saw anyone playing a bass looking like that somewhere, I would simply admire it, and probably ask the owner a few questions about it if that possibility arose.
