Nice little amp!
I've had this amp for a few weeks now and I'm really enjoying it.
The green channel has a nice crunch sound when the gain is up but cleans up nicely once you turn down the gain. You're not going to get pristine cleans with this amp, but you'll get close enough.
The red channel can take me anywhere from classic rock to searing leads and metal. You get that classic Marshall growl. The distortion gets very compressed once the gain knob goes past 12-1 o'clock though so I never go past that.
I don't find the Tone Shift button very useful. Maybe if I was going to play some Metallica or something that was very scooped I would use it. The Deep switch is what I use to go between classic and modern metal tones as it really pushes out the bottom end.
I use this mostly in triode mode and it is still loud for at home use. I would say that in pentode mode you could easily gig with this with a little help from the PA.
My only real complaints are the stock tubes and speaker. It was VERY fizzy when I first plugged it in. I finally swapped out the speaker for a WGS Veteran 30 and changed the preamp tubes to be a mixture of Mullard and JJ and the fizz problem was solved. The speaker swap was the real solution to the fizz, the tubes just dialed back the gain a bit and made the gain knobs have a bigger range to work with. I could have kept it completely stock and enjoyed it, but I had the parts laying around and found that using them fixed the couple of small issues I had with the amp.
If anything happened to this amp I would more than likely buy it again.
