i have a Mark IIc (not +) short head, 100w, simul, reverb, eq. While it sounds pretty awesome, i often find it lacking in versitility. As many complain about, i can't really get it to sound great clean AND distorted. I'm thinking of selling it and getting a mark IV head instead which offers different settings for each channel. I mainly play stuff ranging from indie rock shoe-gazer type stuff (built to spill, pavement, radiohead, etc.), more rocky pop stuff (weezer, foo fighters) and also more classic stuff (led zep, pink floyd, etc..). the guitar sound that I would mainly be shooting for is the weezer/foo fighers/floyd realm rather than the shoe-gazer stuff since i can do that on just about anything. Do you guys think i would be happier with a markiv? There is not much opportunity at all to just go try one out, especially not at the volumes I usually play at, so i'm just looking for some opinions for now.
