I had three EVJ's-- a stock combo (V1 or V2-- not sure), a slightly modded head with a couple of the sewatt.com mods and upgraded tubes and then a full-out modded head with a "Marshalized" Turretboards.com circuit board, Heyboer OT and upgraded tubes (Telefunken 12ax7, JJ EL84), plus tonestack switch and standby switch. All sounded pretty good, though the fully upgraded one really stood out and had awesome "18 watt" type tone. I sold that one when I upgraded and I don't regret upgrading, but I miss that little tone monster!
