Have searched for a dedicated thread but couldn't find one. I need help beyond the manual that came with the pedal.

When looping I find that the volume on the loop is lower than true. I send guitar and vocal through it and the problem is that the drop in volume means I have to fiddle with levels of the clean signals through my PA.

Does anyone have any ideas? Everything that I find from KT Tunstall and others seem to gloss over setting this up through a PA.

How do you do it?
