Did a short recording session yesterday for some scratch tracks for a couple of song demos. The drummer was using a 22" Zildjian K Custom Dark Ride Cymbal. There was an annoying (to my ears anyway) ringing sound that when I first heard it I thought came from mic placement, but after several adjustments to no avail, I realized it was the cymbals sound itself. I had him add another felt washer (larger than was previously employed) and it seemed to correct the problem. Later in the session when he was playing with more "attack" I heard it again (hard to descibe but almost like a feedback ring.) Anyone have any thoughts about how to set this cymbal up to decrease this without asking him to use a different cymbal? I know I can probably EQ this out but would prefer to solve the issue prior to doing the final tracks on these songs. Also he was using a jazz kit with a very small bass drum, 16" I believe. I had him tune it down as much as possible (it began to buzz any lower) but I was wondering the best way to get a deep rich sound from such a small diameter drum?
