seweryn_sobczak Posted March 27 Share Posted March 27 Hi! I have a Line 6 Helix LT, and two amps which are Marshall JCM800 2210 and Marshall Valvestate 8100. My dream rig is a helix as a pedalboard going out into both amps. I would like to use the EXT Amp out to control both amps at once. Both are using TRS connections (one is for channel and second for reverb). How can I connect It without any risk or ground loop issues? Do i need external device to separate them? Or just a Y cable would work? (i think no) If Its impossible maybe there is any solution with Midi out? Please help! I can build the device myself but I need to have any advice from someone who knows the electrical stuff better than me. Quote Link to comment Share on other sites More sharing options...
