Here are some photos of the Orange Crush 12 guitar amplifier that I found on the street a week or so ago.
It has a surprisingly good sound. You can get a very good jazz tone without a lot of effort. The controls are very responsive.
For now I put the cover on my Roland Cube 60 and am using this amp instead. Today I found an AC power cord for it on the street (with a broken TV that I didn't take).
