I believe he recorded some of the Heaven Tonight album with that bass. He didn't do a lot of recording with the 12 string. What producer wants to hear THAT?!?!
I'm quite enjoying the Hamer I just bought from Baz.
Heaven Tonight was 4-string except the title track which was the first ever Hamer 12-string. Dream Police, the next album, featured the Alembic 8 on a couple tracks, Gonna Raise Hell and Need Your Love, which everyone thinks is 12 but are actually the Alembic 8.
What model Hamer do you have? I wanted a 12 ever since Heaven Tonight was released, that photo of it on the sleeve called to me! LOL
Took me a few years before I got my first, a B12S, which is closest to the original you can get. Quickly bought a second B12S as a back-up and the band took off across the country, the basses always had a small crowd at the front of the stage. HA
After that band broke up in the late 90s I sold one of them but I still have the other.
