I just bought a Digitech GSP2101, and I'm looking to hook it up to my Mesa. A problem I ran into is that I want to use the analog section for EQ'ing my clean tone, but don't want any EQ'ing on my Mesa's distortion. By reading the manual, I figured out how I can do this by running a Y-cable to both the GSP and the Mesa, using both preamps for clean and summing the outputs, but use only the effects loop for the digital section of the GSP for effects on distortion. My question is - Will this cause some sort of impedance problem or significant signal loss? I won't be around my gear to test it out until later this weekend, so if anyone has some advice, it would be greatly appriciated.
