So my friend took this from his girlfriend, and I just stole it from him.

It's a GA-435.
There's just a volume and a tone knob, and you turn it on by turning the tone knob up.
It actually sounds way better then my regular bass amp
(Crate BT-15) it just buzzes and make some awful noise randomly, but when it's not, it sounds great.
I checked inside, and it's just a little circuit board and a speaker, it's pretty empty in there.
I did some websearching and came across nothing, here's a ****ty picture:
