Re: randall amp
I had a Commander bass head. They started production in the late 70s, went on for about 10 years I think. They are solid state amps, but some of the earliest. Kurt Cobain used one for the recording of Bleach. Thats pretty much the only information I have been able to find out about them.
I quite liked mine for use with guitar, but it just wasn't loud enough.
Sorry I couldn't be more help, but they seem to have been forgotten. I tried to contact Randall, but since thier takeover by Washburn, they have completely changed.
