I also truly love my amp808 and les lius. Private message Sean here on the forum. He also posted awhile back w his personal email. I don’t recall it so you’d have to search his content. I don’t mean to insinuate that you haven’t thought of this, but at least one of my Lovepedals will not pass signal if engaged with a dead battery inside. That left me head scratching more than once. Just in case you haven’t checked the battery. Otherwise, get in touch w Sean and he’ll make it right.
