Hi ppl

At band practice last night, the 'sound man' was saying that he got a
buzz ing sound from my kit, but not from anything else. If my
Behringer amp was inbetween the kit and the PA, there was no buzz. So
he said that new, digital equipment isn't earthed properly.

Does he have a point, and if so, what can I do about it?

Cheers

PS. Keith, you're doing a great job here. I've run past your house a
few times recently.
