Ah but that just confirms exactly what I was thinking. Try this: 1. unplug your amp,and any headphones, etc. 2. Turn the stereo gain plugin at the end of the chain up until the output LEDs show red when you hit it hard, then back it off a tiny bit so it never clips (goes red). 3. Go to the gain settings in the menu and turn down the output gains. 4. plug in your amp and slowly turn up the output gains until it seems that your amp is getting the level you want.
0db out is pretty hot. Your amp can (heh) amplify a much quieter signal. Perhaps its counter intuitive, but you will actually have BETTER sound quality by turning it up digitally as loud as possible and turning DOWN the output gain to a reasonable level. Because your output gain has been so high, your patches have been designed to output teeny little quiet signals that get boosted by the output amp inside the MOD.
Does that make any sense? Give it a whirl and let me know if it doesn’t work.
