This board is designed for "live use"... I'm not adding overdrive pedal plugins before the amps because I prefer to use real overdrive pedals just to boost between my Guitar and the Dwarf... it also save a little the load of CPU proccess... I'm working with 4 snapshots 1 - Vibro (Clean) 2 - JCVM Crunch (Low Gain) 3 - JCVM Crunch (Mid Gain) 4 - JCVM Lead (High Gain) I'm using OwnHammer IRs. MRBW 4x12 for JCVM and Tweed CQ12 for Vibro. Enjoy!
