I had the Mids for the Lead channel on 7.
The amp sounded great, but had no punch because I just couldn't turn it up loud enough to let it breathe.
I really like the amp, but I've been playing some of my other amps this week and I really like some of my other amps much more. I have a Soldano Lucky 13 that is absolutely incredible, but it doesn't have a loop (I could always add one).
I think my DC sounds more full also and is so much easier to dial in a great tone.
As for R2, I think it's a matter of personal taste. It's ok, but I have other amps that do Blues tones so much better also.
I don't mean to diss my Mark IV, like I said, I love the options and the fact that this amp can get loud enough to kill small furry creatures. I do think that I could take a beat up DC-2 or 3 and add the Triode, Cathode Bias, and a few other mods and make an amp that could outpreform the Mark IV or the DC.
Besides, now that I've been married for 5 years, I tend to trade guitars and amps like I used to trade Girlfriends.
