Ive just bought a Zoom G1XN effects pedal but Im having problems setting it up. Im playing it through my amp a Roland Cube 15XL. Ive plugged into the clean channel and have turned the Bass Mids and Treble right back. As soon as I try and turn up the amp volume from 0 it starts to buzz pretty loudly. Ive messed about with the amp settings and the master volume on the Zoom but I cant get rid of the buzz.

Has anyone got any tips on how to set it up properly ?

Many thanks
