Awful interference with electric guitar
I did a gig today in a residential centre using just my S1.
I was using it on battery power but as I was using my Telecaster I decided to connect the T1 so that I could pop some delay in for my Shadow's songs.
I was using a TRS balanced cable to connect the T1 and S1 and I made a point of turning the Tonematch off on the S1.
For some odd reason my guitar then began to develop a nasty hum which stopped when I touched the strings.
I tried the guitar through my Fender Deluxe when I got home and it's perfect with no interference at all so obviously there was something wrong with the way I had set the S1.
Any ideas what might have caused the interference?
I wonder if it's because the T1 was on power supply but the S1 was on battery. Could that cause the problem?
Grateful for any thoughts.
