Re: Mesa Mark IV finally here.............ah.....
I use the combo version (I think its a 1x12) of the Mk IV for gigs and sometimes I use it for band practices. Its truely a pain in the ass when playing at very low levels with the master at like 3. Every change EQ change you make is always "too much." Turn the bass down a tad and you are too bright, raise it up and you dont cut through. Its really hard to deal with, but once you get it, its amazing. I had a great lead tone set up for a while, but I didnt write it down, to come back a few practices later with the knobs all changed. So now I just bring my Gibson amp to practices, 1 knob, no mess to deal with.
Clean channel is pretty much blackface fender tones. Its pretty close to that, very big sounding. Clean sounds IMO are much easier to dial up with that amp compared to the distortion. Even though its hard to set up, when you are doing gigs and you can crank it a good amount, the thing is cooking! I had it on the crunch channel with low gain settings and slighty bassy setting and high volume and boosted it up with my Fulldrive II on the flat mids setting. It was amazing! I never gotten a tone like that before in my life! It was indescribable! And then another time, I was using the MkIII with a keeley modded blues driver and that sounded pretty damn good too! Gave me a great pete townsend/hendrix tone. So good luck with setting up that one, but once you find your settings, youll be set and very happy!
