Hey on terms of settings, (btw, those were just how things were set when I brought it home, I have changed things up, but treble and bass controls are still pretty similar to me) I have EL34s in there, and I think that has a lot to do with it. Also, what cab and speakers are you running? V30s are pretty bright speakers and that could have something to do with it. I have a Vader 2x12 with Eminence Legends, and those are very clear, and bottom end boosting speakers. I am running the bass low, because as the manual said, much bass on the regular EQ can create flubby sounds at high gain levels, so I compensate for the low bass by boosting it on the GEQ. And finally, I may just be running my presence and treble high because I just came from my ENGL, which was an EXTREMELY EXTREMELY bright amp, and perhaps since my ears have just been used to that, a brighter sound is just what I am gravitating towards. However, I have to say that the Mark V is way less bright and harsh on the ears than my ENGL was
