Great little guitar or bass amp with a cool warm tone. Located in Forestville now, at my friends house. I live outside of the US now, so I think it is time to sell this. It has a not very professional custom fabric grill on it, not the foam that would come on these earlier mini brutes (this probably dates to the early 80s). This is the Mini Brute III, no reverb, 15" speaker.
The tolex/vinyl is in pretty good shape, there are a few small chips missing, and, most notably, the original handle is gone and replaced by a handle that has a smaller footprint, so the extra holes from the old handle are visible. . Also, the back has two extra hooks for winding the cord, and has a stencil stating "SRJC music dept", the previous owners of this amp before I purchased it. I thought it looked cool, others might disagree with me.
I also have a vintage ampeg portaflex fliptop amp listed as well.
Here is the manual for this polytone:
