Anyone ever used a gr20 or gr55 with their axe units?? I have both and I want to use them (preferably the 55) with my axe fx. The 55 requires 2 amp Inputs (like most fender amps have) and the axe only has 1 guitar out in front, is it possible to route this through the chain somehow? Because the gr uses 13 pin to the guitar it has be be first thing going into my guitar. Thanks guys!
