Today I've tried to set up my pod go with a headrush frfr 108. I've created a preset that sounded great on my headphones. However, when I plugged the speaker, the tone became really muddy and overall bad. The problem seems to go away when I turn off the cab sim, but then it all sounds too harsh, and I don't really intend to play without the cab sim on. I can't find any way to fix this nor have any idea why it happens.
