Hey mates, sorry to ressurrect a zombie thread from across the pond, but I've been looking for a bass like this since I traded mine away back in approx. '92 or '93. This is a Kaman GTX-53 five string active bass. As I recall, the treble knob on this beauty mainly added noise, so I kept it rolled off, but it had super deep low end(and I'd always wondered what it would've sounded like with upgraded pups). The neck has a super -fast feel on the fretboard(but the finish on the back seems to be really slow), and the weight is not bad. Hey JimRyan, does your housemate by any chance still have this and would he consider selling it and shipping it to the States? Here's another example of the same bass in the only other color I've ever seen on this model.
(BTW, I nearly freaked when I saw this one in a pawn shop in Nashville, not too far away from where I live!)
