I have put every delay chorus and compressor in this spot in the chain and all are acceptable. I put the Echo Park in there and it HUMS so bad it is nearly impossible to use. Is there any fix out there. what great pedal only to be such a complete loss because of 60 cycle hum.

My rig is

Voodoo GCX switcher

loop 1 Comp

loop 2 trem

loop 3 H2o delay chorus

loop 4 Echo Park

All ran in the front end of egnater 4212 Tourmaster

Any time I kick it on yikes!!!!!!
