Greetings,
I played a wedding on the 16th floor of a Boston hotel last night. To my dismay, the second I plugged into my amp my Essence was broadcasting a local radio station. I tried different outlets, no pedalboard, groundlift, different plugs -nothing solved the issue. I got through the gig with my filter rolled all the way off, as well as the Q off, which minimalized the problem about 90%. Looking back, I had this problem once before: another wedding gig, on the top floor of a hotel in downtown Providence.
I feel pretty comfortable ruling out weddings as the culprit here, which leaves the elevation. Electrical is also unlikely: one venue was very dated but last night's was a newer build.
Are there any methods or products to deal with this?? Both times this quickly became an embarrassing issue during a high priority gig, which I would not anticipate with a top of the line instrument. Both times, no one else in the 7 piece band was affected. Thanks for your help.
I've encountered this with various amps over the years, in fact you can here this happening right at the end of one of those percussion pieces I recently posted, I was using a Peavey amp and Gibson guitar.
There are discussions online about this topic. Here is one detailed description (scroll down a little).
