Starting measurements
Three numbers, two different tests
Batter lug
49.0 Hz · G1
Mute the resonant head; tap near each batter-side lug.
Resonant lug
74.0 Hz · D2 +14c
Mute the batter head; tap near each resonant-side lug.
Assembled fundamental
32.7 Hz · C1 -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 batter head stays wrinkled
Raise the batter target until the head seats evenly. Physical seating is more important than reaching 49 Hz.
The result is mostly room boom
Move the microphone closer to the lug being tested and use a lighter tap; verify the final sound from the playing position.
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.
