Question for all you experienced mesa dudes. Im primarily a bedroom player at this point, I want to hear opinions of these amps played at fairly low volumes. Alot of people seem to swear by the iv over the v. I typically play in the styles of pantera or lamb of god, alot of chuggy stuff. Also is it worth getting the 90 watt mark v head over the 35? As in does it sound alot better? I currently have a 5150iii and am looking for a different flavor.
