I have an opportunity to purchase another Mark IIC+. I have 2 simul-class models, one is an upgrade from a regular C,. Neither have EQ and the one I'm looking at does, however it is not a simul-class. It is a 100/60 watt. I have never owned one without simul-class and was wondering what the difference in sound is. I thought it would be nice to have one with EQ. I don't play metal, mostly classic rock, so I don't think the EQ is as important to me as the overall tonal qualities. Any thoughts or input would be appreciated.
