Not to be confused with the real gear gurus on this site, this is something I read in a book I have.
The polytone minibrute is quite the amp for small intimate settings.
I also read it was primarily designed as as a jazz amp, so maybe it won't work for heavy metal/hard rock.
I didn't read how much it costs. Maybe it's the amp equivalent of the D'Angelico excel archtops, and you don't even wanna go there.
