Hey all, For a song I need two things: one being clean with delay and reverb and two being overdrive (from my pedal in the fx loop) with nothing else. Basically I want to switch between <fx loop> and <fx loop off - delay - reverb>. Can my M13 somehow do this? I found something about it but this requires switching scenes which doesn't quite do the trick for quick switching (or I am doing it wrong ;) ) Help is much appreciated! Cheers, Marnix
