Been on a bit of an EVH amp kick this week since I was tweaking the preamp tubes in mine. People get confused over the various models (myself included) so I did some lo-fi photo editing of the different heads. I'm a nerd. This does not include any combo amp versions or the earlier Peavey 5150 line. Things to note: -Only the "original" 6L6 line is available in both black or ivory. -The 50w 6L6 rev 2 introduced concentric volume and gain controls which rev 1 did not have. Kits are available from Fender for authorized service centers to bring rev 1 amps to rev 2 specs with concentric pots. -The LBX amps use EL84 output tubes. -The only amps with a power reduction option are the LBX models. -The only amp without a Resonance control is the "original" 100w 6L6. -There are 112, 212, and 412 EVH cabs available in varying matching cosmetics. The 412 cabs use 20w G12 EVH signature Celestions (relabeled Heritage Greenbacks) and the others use 30w G12H Anniversary Celestions. -All EVH amps and cabs are made in Mexico. There are other details such as slight tone tweaks between the models, how the green/blue/red channels differ, etc... but that's a whole other discussion. OK.... I've dorked out enough for the day. Done.
