So I usually don't have issues like this, but I'm stuck. So I'm dialing in a nice ambient edge of breakup preset, and so far it sounds amazing! Only issue is that on lower notes it feels like the amp is giving out, which I'm thinking is just one of the deeper amp block parameters? I've turned off Sag, and I'm starting to think it has to do with biasing of the tubes, but I have no idea what Half the advanced amp parameters even mean?? Anyone think they can help?? I'm using a Les Paul with Seth Lover's into the axe FX w/ I/O at 52.9, into my interface and to my studio monitors.
