I bought the Scarbee Pre Bass around Christmas on impulse. Mainly out of curiosity...
The kicker is, I was a bass major in college! My excuse was that my keyboard skills are horrible, and I just wanted to "diversify" & experiment
Moral of the story is, I don't really use it. It's not that it sounds "bad..." It's ok.
I think it's super bright, though. And I'm too lazy to learn the intricate keyboard tricks to make it play nice.
If you want to try it out for cheap, I'd probably be willing to sell my license for roughly 1/2 what it cost.
