And take all those settings and suggestions with more than 10 grains of salt... because he is running one more rig in parallel to the vh4; 2 amps with 2 different cabs and speakers ARE going to influence each other's tone quite a bit. Plus the Lords of Kobol know what custom mods have been made to both amps along the way. (And allegedly neither the mics used nor the axe itself are anything to really write home about - the bottom line is, when you take the player out of the equation, his tone is a whole line of things that shape and alter the end result)
If you are really determined and don't have to worry about a second guitar player in your band and have that mid-range all to yourself like Adam does (most of the time, Justin is probably somewhere down there with seismic activities in terms of Hertz...and Watt), then try combining a v30 rear and k100 front and that should give you a giant leap forward. Suggestion from the source. So say we all.
