How to stop delays in Helix Posted March 20, 2019 Thanks for all the help. I didn't realise that's how real pedals worked, I can understand it not being a priority for Line 6 if that's the case. I have a song where there is a quiet bit with a gradual distorted feedback effect (100%) that goes insane to a drop point where the band comes back in. The problem is when we play the song twice in rehearsal . The feedback dial assignment should suffice.
