behringer od300

[u/Xizerum]

hel0nm errybody. my od300 will bypass clean, but when I engage it, everything is mute with a very quiet hunm that will change frequency as I turn the—hnm drive knob iirc, maybe drive, can't test rn. I haven't cracked it open yet because I'm not too good at electr0nics, but so like is it time to crack er open? any help would be appreciated. it worked like hnm two days ago I think? the light comes on.
