I almost never use R2 so I think of the (input) volume control as a dynamics control for R1. I have it around 7 right now, but I change often depending on other factors. If I do use R2, the volume control works best around 7-9 IMO - nice crunch on R2 and even volume transition between channels.
I also have the volume knob pulled currently. At home or recording, I don't need the extra treble, but gigging or playing with a band, it helps to cut through and add some bite.
I have my treble at 5. Again, sometimes I keep it lower playing at home or recording for a smooth tone.
This knob is also pulled for my upper-mid gain on the lead channel.
My bass is always set between 0-2 - at 2 its more bass than I like (especially with the EVM, but its a good amount with a Celestion), but just sounds/feels right: I think the preamp just functions better with a bit of gain in the lower frequencies.
This not is not pulled.
Midrange at 5.
Master to taste. Right now, its between 1-2 playing at home.
Not pulled.
Lead Drive is around 3 - this is still pretty clean, I get my drive from a TS or Rat and end up with a really smooth, fusiony lead tone, but I need the treble high on the lead channel. Sometimes I crank it up to 5+ for more grit (with or without a dirt pedal).
Lead Master is between 1-2 right now IIRC.
I have this knob pulled, but if I really crank my amp up for, ie, an outside gig, I might need to adjust the treble (turn it down).
I keep my presence between 0-3. At 0 the amp gets a bit dark and lost in the mix, but I find the presence circuit adds some noise. Above 3 just causes ear fatigue IMO.
Reverb at 3.
I just switched back to using the GEQ on auto rather than using the GEQ always on and an EQ pedal for a lead boost. The GEQ + Lead channel just sounds awesome. I have mine set the opposite of most of you: I have an upside-down V with the 750hz slider the highest. I keep the upper-mid and treble above unity, lower mids at unity, bass below unity.
I'm also currently just using Class A with EL34's - I prefer the creamy mids from the EL34's when using my EVM. But with Celestion speakers, I like adding in the punch and articulation of 6L6's.
I use a Hollowbody with PAFs.
Think Trey Anastasio: early 80's TS9's > Black Ross Compressor, plus I also pop on an early 80's AD9 with my leads.
