My Guitar goes into an ABY-Switch, A-> AmplifiTT, B-> Realtone-Cable. Guitar-Sound InGame is muted, my Soundcard is the AmplifiTT. It has an AmpOut which goes to Active Monitors Channel B and LineOut to Channel A. So I can mix the sound at the Monitors. Through the amp-out only the modelled guitar signal comes out and through the lineout the game-sound without guitar. It fits perfect to me.
