Just bought a brand new Tri Parallel Mixer. Have a little trouble, I hope you can help.
When I have a delay pedal in any of the three loops (no other pedal) I get a small fuzzy pop when the tri mixer pedal is pressed. Unfortunately with the delay and the looper this is repeated, over and over.
I am using it in the mode for trails.

Is there any way I can stop this?

I have tried different cables, going straight to a computer audio device rather than my Marshall. Im using the supplied power plug.
Has anyone else have this problem?

I wanted to have my long delay trailing off while I playing over it with my guitar unaffected by the delay.

Ta.
