I've been laid up with a hernia (back) for a few weeks, unable to get to practices for either of my bands, rough few weeks. So I've been reading a lot online and watching this thread pretty closely, (and lurking on this board) -making notes about how I might improve my sound when I got back. I'm very happy with my Mark V and was really at a point where I wasn't tweaking the knobs too much anymore, if anything just the overall volume, and minor reverb and 3 band EQ stuff to match the rooms or other instruments.
One band is throwback 80s-90s style Trash/Crossover. The other is a 70s and 80s punk cover band. Mainly the thrash band is channel 3, Extreme or Mark IV, and the punk cover band is channel 2, Crunch. Channel 1 gets very little use. 90 watts, 5 band EQ, in a moderate "V" for all 3 channels. I was riding the channel master high, 12 o'clock, if not a little higher and keeping the master volume lower as a result, the Solo knob could barely be touched, a millimetre above the zero position was too loud. It worked, but I wanted more control.
Based on the recommendations in this forum, I went back to experimenting with the Preset EQ knobs and started running the Master volume higher and channel masters lower, what a change, I really liked how the gain opened up, less saturation, but still brutal, the Solo function became livelier as well, the knob could go a lot higher and I have much more control over it's function.
Man this amp is something, with my old Marshalls and Hiwatts, I'd find a setting, and that would be the end of the knob turning for years. The Mark V has so much character and control you can keep experimenting and finding new sounds and ways to use the amp.
Thanks, now you guys can go back to talking about the 10 and 45 watt modes.
