HI guys/gals As the topic suggests, I was hoping one of you talented bright rockers could help me figure out how to connect my HD500 + GR33 together. I have a Godin Freeway SA so the 13 pin connections etc all there. Basically I would love to be able to switch between using guitar+Hd and then to GR33+guitar (via 13pin obviously) Any help would be super! :) Thanks
