I play a mini recto at my church on Sundays, the church is in a school building that is ony a couple of years old. When I plug in there I get awful hiss and buzz from my amp. It only happens there, doesn't do it at my house or at the practice place. I'm thinking it may be the power even though it's a new building. What do u guys do about noise? Would a power conditioner help? If so which one.
