I have set up my HELIX to use an external pedal through the SEND/RETURN FX loop. However, this does not seem to work through FX LOOP 1 or FX LOOP 2 - these are completely silent if I run the padal through one of these. FX loops 3 and 4 work fine. Have I missed a setting somewhere or have I got a problem with the HELIX. Any ideas anyone?
Tx in advance.
