I record some piano stuff every now and again, but I only have a Rock Band USB mic and I lay it on top of the piano, which is obviously not very effective should I get a special kind of microphone or what any tips would be appreciated I just want to get rid of the majority of the feedback perhaps I could just edit the audio later to suit my needs..
