New arrival! It's a Kay electric bass; not sure of the model but it looks to be one of the later Japanese Kays from the 70s. Obviously patterned after a Gibson SG, but if you look closely you'll find that it's full of little oddball touches. There's a little foam piece underneath the bridge cover that's slightly muting the strings, while the "K" on the headstock seems to have flipped upside-down.
The pickguard is raised slightly, which has a neat overlapping, two-level effect with the control plate, and the dual pickups have a nice "gator-esque" tolex covering. A very cool, playable old bass with lots of character.
