I have the AT-212 combo.
I f'n love it , I run it in stereo with my 5150 combo and together they kill.
the clean channel is very nice, tons of head room.
The 2 gain channels will cover just about any type of tone you're looking for.
Set the Rectifier to "A" and it gives you more of a classic rock
AC/DC type of break up.
"A/B" is good for most everything else, and the solid state rectifier gives you the tightest sound.
the contour switch is some sort of mid scoop that adds some compression. It gives you a huge range of tones out of one amp. You can go from AC/DC crunch to Dimebag sizzle just by switching channels. Van halen
, and Megadeth tones are pretty easy to dial in.
Turn the contour on and pan it to the left and you can get a real Mesa dual rect sound out of this thing.
It sounds great loud and it sounds great at bedroom levels, but it's got 2 120 watt speakers in it so it really doesn't come alive until you turn it up somewhat.
I find that if I max the master volume and control the volume from the channel controls it sounds alot warmer. I also run an MXR 10 band EQ in the loop and at low volumes it really brings the amp alive.
The only thing I question on these is quality.
but time will tell. Great bang for the buck!
When I bought this I was out looking for combos and it came down to this, A JSX, and a 5150. I look at this as a poor mans JSX, they sound very similar, but for 60% of the cost. I had never even heard of them and when I plugged into it I was just blown away.
BTW I've been playing on and off for over 20 years so you can take my opinion as being at least somewhat legit.
I've been around the block a few times
