Hi efstein,

To be clear, all the reverbs work correctly? If the H9 is new to you, I'd suggest a factory reset to make sure it's not an issue with presets or a routing setting that you aren't expecting (perhaps the dry/wet setting was left on, or something similar) .  To do that, reboot the pedal while pressing both the Right footswitch and the knob until the pedal indicates "INITIA"

Please let me know if that works, or if it's still an issue.
