He runs his Marshall eq basically the same as I run mine. Same as Eric Johnson. A lot of players like to crank the eq up, but, when you're playing at a loud volume, you don't need it. I run my treble all the way down, or, depending on what head (Germino) or MTS module (Jaded Faith JTM, Salvation Duoplex, or, SYNERGY Metroplex) I'm running, sometimes I add just a little bit of treble (on the Metroplex module, I run the treble at about 1, or, 8 o'clock on the dial.) When adjusting my bass knob, I start with it all the way down, play a chord, and then turn it up until the sound starts getting filled out. Usually, at about 3-4, or, clock position 10 o'clock. Any more, and it sounds all mushy, with little low note articulation. Mids, same thing. I turn the mid up just enough to give the sound some body, but, not enough to make it harsh sounding. Usually ends up at about a little less than the bass knob, between 9 and 10 o'clock. That's all you need with those heads. Everybody over-EQs their heads, and, at a loud volume, the treble hurts peoples ears if it's past 10 o'clock, the bass just turns to mud, and farts the speakers out, and the mids sound honky and brash.
When you're playing at such a loud volume, you don't need to add a hole lot of eq. Same with my overdrive pedals. Less EQ=full, balanced pleasing tone. I've been running my amps and overdrive eq like that all my life. Always sounded better to me.
