I bought my M-80 a while back at GC, i don't really know anything about it. The first day i heard of one was the day i bought it. It is called a, "Fender M-80 Bass." I don't know a lot about the age of it. It looks like it is either a late 80s or early-mid 90s amp. It has two inputs, and effects loop, 3 band eq (obviously not graphic eq), chorus, compressor, a foot switch input, one PA output, two speaker inputs, one 15" speaker, and i'm guessing the 160 watt rating is at 4 ohlms because there is an empty speaker input, so i'm pretty sure the speaker is an 8 ohlm, too. It is a closed combo, so i would have to unscrew the screws to see the back of the speaker. Sorry, i don't have any pics. Just wondered if anyone has heard of it. I think it is funny that if i scratched off the 8 and the hyphen it would say "M O BASS" like the SWR head, but it is obviously not an SWR, and it is a combo.
