Drum Tuning Tips
Snare buzz: be mindful of the pitch of your snare in relation to your toms (especially the mounted toms). If your batter/resonant snare drumhead is a similar pitch to your batter/resonant tom head, you're going to get a lot of snare wire buzz when you hit the tom. It's almost impossible to remove all snare buzz, but you can minimize it by keeping this in mind when tuning. Snare wire buzz is actually wanted in most recordings, and is added to a lot of bass drum and tom samples, because a drum kit sounds strange without it.
New drumheads take time to "set" - use them for a day or two and retune as needed. They will stretch and change slightly over this time. After this they should be much more stable. Remember this if you're planning on recording or playing live... don't use brand new heads that haven't been broken in.
Different drums have different tuning ranges. Depending on the size, shell thickness, and shell material, each drum will have a different sweet spot range where it sounds the best.
Tune your drum properly before adding dampening. Don't use dampening to hide bad tuning. Once the drum is well tuned, then you can think about the range of dampening and sound control options available.
Check the other drums as you're tuning. Sometimes a drum sounds good on its own, but terrible in the context of the whole kit. Check that the sound blends well with the rest of the drum kit.
Your drums will sound very different when combined with other instruments. This is true for both LIVE and when RECORDING. A lot of your sound after the attack will probably be buried by the guitar, vocals, bass, keys... The extra ringing you're trying to get rid of will disappear.
Your drums will sound very different from the audience's perspective. Ask someone to play your kit and walk around the room, especially at a live venue. The room (and any drum microphones) will have a big influence on your sound, and different places may call for different tuning, more or less dampening, or different playing styles.
Tune the floor tom first. If you're tuning your whole kit, start with the largest drums first and work your way up to the smallest. Starting with the lowest sound you're looking for will mean you'll have the best starting point and the best idea of how wide your kit's tuning range can be. This minimizes the need to make adjustments later if you tune the smaller toms too low.
Candle wax can be used to cheaply fix a damaged bearing edge. Rub some soft (warm) wax on the damaged area. Don't overdo it, and don't cover the whole bearing edge - keep it focused only on the small damaged area (otherwise the wax can give a strange tacky sound). If this doesn't work, you probably need to have the bearing edge re-cut by a professional.
