Recently realized that apparently these pedals, or at least the 2nd versions, are capable of being used as a 2 channel preamp in which you're able to run one output for cleans and the other for gain. But how exactly? Would it be say, into the FX return of my amp for gain and the output for the front of my amp for cleans? Using whatever pedals I want for each output? At least that is my understanding at this point. Am I correct? And if this is indeed how they work it could be exactly what I've been needing. An alternative to an expensive midi switching system. Seems that the Vt2(the VHT/Fryette clone) which would easily be my first choice is discontinued and hard to come by, so I'm stuck between the P2, D2, or E2. I'm leaning P2 as I've never owned a 5150 variant but I'm not sure. Which of those 3 thumps the hardest? What do you guys think?
