RESOTUNE (tm) Plays crystal time based precision tones through two bottom mounted loudspeakers, then listens to the drum head as it vibrates in response with two microphones also mounted on the bottom. By sweeping over the tuning range and listening for resonant peaks RESOTUNE very precisely identifies and saves the fundamental note and the first overtone. RESOTUNE then captures a very specific reference measurement for the one lug close to it. This reference data is then used to measure the other lugs for fine adjustment. The front panel CLEAR LEDs even show which direction to turn the lug being measured to perfectly match the reference. When all lugs have been adjusted to indicate CLEAR (green LED), they will be matched to a much higher precision than possible with any other tuning approach. You will experience an open "Clear" drum tone than sounds great and even feels good to play. I have even had customers report that they were able for the first time to clear a problem drum they've owned for years. Caveat, we can't promise to make problem drums wonderful but the direct measurement of sound coming from the drum head instead of measuring some related mechanical characteristic has a a better chance of success.

While this remarkable ability to clear drum heads to high precision is benefit enough, the RESOTUNE electronics allow you to also tune to specific notes, and/or measure and capture the precise tuning you are at and store for future use.

The figure below shows typical tuner orientation to read the lug with key inserted for tuning/clearing. Dotted lines show orientation for adjusting next lug to the right. In general you should only need to make large adjustments to each lug only once, It is good practice to make a second round of measurements is one or more lugs were way off.

Now that clearing drum heads and restoring favorite tunings is a relatively simple procedure you will now be free to explore unconventional voicing and perhaps even pay more attention to the actual notes we tune our drums to. If a tuning experiment doesn't work, it's relatively simple to just return to your previous tuning and try something else.

Our goal in developing the RESOTUNE system is to provide the measurement tool to read exactly what your drums are doing in real time, not to tell you how to tune or voice your drums.  Please see about drums page for more general discussion about tuning and how drums resonate.
