Ampeg SVT 3 PRO amp.
Anybody who knows bass amps will know the legacy of this amp. It's a hybrid of solid state and tube pre amp. Excellent sound with 10 band EQ. Separate buttons to boost hi/lo and a 'bright' button. Also a mute button which I've found handy.
275 watts @ 8 ohms
450 watts @ 4 ohms
There is a line out at back.
From my understanding of the serial number on the back I think this amp was made in 98/99. And I think was apparently the first generation of them made in USA or something like that.
I bought it 2nd hand and the guy I bought it off said he put it in the case as soon as he got it. So it's been gigged but never out of the super sturdy case.
Overall it's in excellent condition.
