Re: Valley Arts-California Pro
I've never played that model Valley Arts, but I can tell you they are very nice guitars (I was looking at them before I settled down with the Grosh).
I don't believe every SD pickup has the logo on the front. For instance, their Antiquity line. I'd check what's on the bottom of the pickups, if the seller will go through the hassle. Most importantly, how does it sound?
Valley Arts Brent Mason model comes with Duncans, so I wouldn't be surprised if what your looking at has them as well.
