The Miller Beer guitars and basses were the result of a collaboration between Hamer Guitars and the Miller Beer corporation of Milwuakee. Miller had been sponsoring up and coming bands and these instruments were made for the band members to use on stage, promoting the beer company. The promotion lasted a couple of years and resulting in some very interesting Hamer guitars.
An album was also released of sponsored bands. The Bass below came with a signed copy.
I was lucky enough to find a set of three of the early iterations of the Hamer Millers. I am working on making it a "six-pack" to hopefully include not only the later models but possibly a 12 string IF I can locate one for a resonable price!
