How to stop recording a loop? in Helix Posted May 25, 2018 I put the Boss RC3 (w/ the FS7 footswitch) in a loops on the LT so I could have more control. But when the block is on even if not using the looper it boosts the signal. Not in a helpful way. I haven't tried to isolate the problem yet so don't know if that's a normal chatacterisitic or there's a problem w/ the Helix. If it's normal it pretty much makes it unusable.
