I'm going to purchase a dual recto and cab but I need a little info first. With the dual recto's, what exactly is the main difference between the 2 channel and 3 channel rectos? also, i've heard it is and it isn't possible to run that head at 50 watts be removing the two outer tubes. Is it possible? mainly becuase I want the recto but i won't be gigging with it. mainly room/garage use and I know this thing needs to be pushed (as do all tubes) to get the best tone. One last question about the cabs.....I've narrowed it down the 2x12 Mesa recto cab with the V30's in it, or an Orange 2x12 w/ V30's in it. I have no idea which way to go. Ahh yeah, by the way, I have a MM Petrucci signature that i would be running through that setup. thanx a bunch for any suggestions.
