Well they just intraduced what they are changing on the Rec's, read below. By the way someone on the Mesa Board was also told by mesa this is true.

Wow, that fixes every single problem we have with our guitarist's Dual Rect. (other than the fact that he's not 100% happy with the tone and wants a new amp anyways ). But just in playing with his rig, a series effects loop would let him use the other channel of his Decimator there, and the tuner out w/ mute would go to his Korg rack tuner so that he can quickly and easily mute and tune.
