Hi peevman, to be clear, to get into the System Settings press the right foot switch and the top right button that says Hotknob. If you see MIDI on the display, it could mean that you’re in the MIDI menu. Press PRESETS a few times to back up in the system tree and scroll to the Utilities category with the jog wheel.
That said, to be honest, I think the easier solution is to lower the output of your drive pedals when you have them engaged. The input volume on the H9 cannot go lower than the 0 dB setting.
