Question for BOSS ME50...

I like mine, but I also like the sound of my head, Carvin MTS3200. I can't seem to get the natural sound from my head. Is it possible to add some delay from the pedal only, and still just use the head?

I have the pedal going out (mono) to the effects loop "in" of the head. It won't work any other way...

Any suggestions?

try plugging the effects loop out of your amp into the guitar input of the BOSS unit then plug your output of the BOSS unit into the effects return on your amp. Plug into your amp and turn on the effects loop, set your delay or whatever effect you want to turn on.
