I ordered a Washburn xb-900 from GCs used site (I called the store about the other natural colored one and was told the truss rod is broken, for anyone who is wondering why I didn't just buy that one). It looks to be in good shape but it appears like it could've been modded.
The knobs are different, and the guy said it was passive and if you look at the pics has a selector switch where the knob usually is. The guy opened it up and swore up and down that it wasn't modded (But then again it is a GC employee).
I can't find any info about a model like this, is it possible the previous owner yanked out the pre and is running it passive? I wouldn't think the Bartolinis would work like that.
Only paid $415 after tax and shipping so I'm not in it for too much. I'll post the pics the employee sent me in a little while.
