Disclaimer: you should be able to use this patch only if you have upgraded to the firmware 331 Beta 1 for testers.
Here is 2-channel guitar rig in the same vein of my high gain patch I’ve just uploaded.
So it is possible to have 2 different gain sound at the flip of a switch.
It is configured with the Friedman BE NAM model which I love, so that you can have a crunch sound and an higher gain sound.
But you can also test with other models, like the Milkman to switch from a clean to crunch sound.
Hope you’ll have fun to experiment!
