I have an L1 Compact and ToneMatch mixer. Normally I output my Gretsch G5420 through a TC Electronic VoiceLive 3 Extreme and Boss Katana 100 amp but I'd like to be able to play the guitar through the L1 alone (less gear to carry), but it sounds awful. I've tried all the settings on the ToneMatch but they all sound like lifeless thuds. The VoiceLive 3 gives amp simulation and sounds great through the Katana. Is there anything I can do to improve the guitar sound through the L1?
