I'm not 100% sure, because I've never seen one up close. My guess is it's made by A Basses. Here's a link... http://www.abasses.com/basses.html
It's called "a piece of crap". Hope this helps (not really) Edit: RAM, the headstock might be similar, but i'm not sure the's an "A" bass. good guess, though.
this bass is a yamaha with all forms of I.D. Removed after it was repainted! I've seen this done before
