Does anyone know anything about these basses? I got a w US Masters bass a couple years ago and I LOVE IT! It's Birds Eye Maple on the body and Flamed Maple fret board, there is no model number or anything on it. I emailed US Masters and they never answered me about it, it has weird pickups and switches. Anyway, this is the most characteristic fretless I have ever heard and the only Passive Bass I own. Anyone else come across these basses. I found their website and could not find this model at all, I can post pics later.
