Tube amp, power level I do not know but it must be at least on the 100w. Level adjustment is a volume per channel, a 3-band eq (including mediums have a switch to select the row action 300, 1000 or 3000 Hz), a reverb. It added a ultra hi switch, which should add to the presence of mitigation and two switches (-9 -6 -3 db).
simple configuration, right? And it is extremely accurate in the settings. Nevertheless it is difficult to have a bad sound with. And I said that this amp is pedal-friendly. Note that I use a Ampeg 8 * 10 (hp eminence) for bass.
Oh the sound ... I have not used to perfect the perfect amp for me does not exist, but this one comes close: it has very sharp rights, which is super nice, super soft crunch, and low (with the cab of course) out of hell. I sometimes play with Celestion blue alnico, and the sound is not far pixies too!
And another huge advantage is that it blends perfectly with any other amp mix.
In short, I take it whenever you want!
Another thing, it works as a bass guitar with a rare thing!
I forgot to mention that I use this amp in the studio where I record my group albums (studio E for not naming them). I tried lots and lots of amps and I know what I'm talking about! This is an Ampeg, so it's expensive, but it is the price of quality. The only thing we can blame him is that he is in a flat spot
