Bought it yesterday after playing it thru the weird 2-12 cab which actually sounded OK and looked brand new.
Fairly versatile EQ section with ultra high and low switches and push pulls to vary bass and treble eq shift points. Also a footswitch activated solo circuit with "voice" and "boost" knobs that I'm assuming is some sort of parametric, I don't have a F.S. Effects loop and pre/post eq balanced out. Power is 150 @ 4 ohms, I have no idea. Pre amp section plays nicely with my SVP. IMO my Demeter is a more transparent pre but it also cost a lot more. I'd gig the Ampeg(s) if I had a gig.
Made Jan, '91 (or was it '93, put the cover back on and I'm not sure now). Insides clean and stickered in 3 different places with the inspectors' names. Power transistors are Mexican Motorolas, inspectors were not.
I'll definitely be keeping it around for a while, probably change the pre tubes. They're branded Electroharmonix Made in Russia. Whatever, they're almost 20 years old.
