Im curious, I didnt see anything in my search here for 12 string bass. So yes I had a Hamer 12 string for a few years and loved it. It was one of the early late 70s ones with the short scale, Two Dimarzio pups with a built in preamp, I bought it from a guy named Hal Hamer who claimed to be a relative of someone at Hamer. It was not the real early quad ones like Tom Peterson used with Cheap Trick, but I did once meet Tom and showed him the picture, and he thought it might of gone on tour as a backup once for him. I had to sell it due to Money matters, but just got a Brice 8 string I love. I love playing these as I usualy end up in power trios and have to fill a lot of space. So anyone else play one at all?
