Starting measurements
Three numbers, two different tests
Batter lug
110 Hz · A2
Mute the resonant head; tap near each batter-side lug.
Resonant lug
136 Hz · C#3 -33c
Mute the batter head; tap near each resonant-side lug.
Assembled fundamental
73.4 Hz · D2 -0c
Open both heads; strike near the center and listen to the whole drum.
The center-hit number is not a lug target. A two-headed drum couples both membranes and the air in the shell, so its assembled fundamental is lower than the individual near-lug readings.
How to measure this preset
- 1Put the drum on a stable surface. Mute the head you are not measuring so the microphone hears one head at a time.
- 2Choose Batter or Resonant in the tuner. Tap lightly about one inch from a lug, avoiding the rim.
- 3Move around the head in a star pattern. Match opposite lug readings before making smaller corrections around the circle.
- 4Unmute both heads and strike the assembled drum near the center. Treat the center-hit fundamental as a separate result, not the target for an individual lug.
- 5Play at normal volume and adjust for feel and musical context. Record the final readings that work for this drum.
If the result is not useful
The drum growls or warbles
Check each lug with the opposite head muted and make small corrections in a star pattern.
The meter hears the room instead of the head
Bring the microphone closer to the tested lug and shorten the tap; low drums excite room modes easily.
Where the values come from
These are adapted starting values from the Overtone Labs tune-bot tuning guide's size-specific examples and lug-pitch method. They are not manufacturer specifications or promises about a finished sound. Drum construction, heads, damping, room, and playing technique all matter.
