Found this one yesterday out pawn shop hunting.
1991 Polytone mini brute I.
Awesome clean tones and very much a Jazz style amp.
OD channel is pretty buzzy and thin like every other Polytone I have played thru.
A very loud amp with killer tone,if you want dirt just run an OD of your choice and it sounds great.
It loves time based effects thru the FX loop.
Really sounds good with both of the tube driven overdrive pedal I have.
What shines on the amp is the amount of clear bottom end signal,very defined and clear and thumps like a beast.
