Hello, ok so basically when im at band practice I have way to much feedback ( ringing noise) coming from the amp, I want some feedback but like all I have to do is not be playing something and I get pretty bad feedback, how can I lower the feedback I get? Keep in mind I still want to be able to get some, but just not as much as Im getting.

Thanks! \m/
stand farther away from your amp, use less gain, etc etc.
Yes, lower the gain, stand farther away from your amp, and don't face your pick-ups to it. If you have to, you can buy a noise suppressor.
