Earlier this year, Alleninallen posted a comment on my November 4, 2012, post, "My favorite head combinations," that led to a detailed exchange on using Tune-bot to tune your drums. I've been asked to re-post the key points from this exchange, since they are buried in comments under that old post. Here they are again, edited for clarity...
Why use Tune-bot?

Studio tested Tune-bot tuning schemes
See the tables below for Tune-bot tuning schemes for several different drum kits and music types. The frequencies listed are the result of dozens of hours of fine-tuning drums in the rehearsal studio. Tunings are listed by drum, starting with the desired overall note and frequency, followed by the frequencies at the lugs for both resonant and batter heads. All toms and bass drums are fitted with 2-ply batter and 1-ply reso heads. After the drum kit schemes, you will find tunings for a variety of snare drums. All snare drums wear 1-ply coated batters with 3mil snare sides.

Darin's Top Ten Tips for Tune-bot Tuning
- Make sure your heads are seated properly--improperly seated heads cause a lot of tuning and choke problems. You have experienced this issue if you have ever heard a head "pop" or "crackle" while tuning, and afterward the sound of the drum really opened up. If your snare drum tone is dominated by dull thuds from the batter head and harsh slaps from the snare wires, re-seat the heads and listen for the shell to begin adding body to the mix! For more information on seating, see "A Note About Seating" below.
- Bring the head up to a reasonably even tuning by ear first, using a cross-lug tuning sequence. Starting from a reasonably even tuning helps reduce overtones that cause "phantom" frequency readings on the Tune-bot.
- Muffle the head you are not currently tuning--I usually rest the drum on a cushion to muffle whichever head is on the bottom.
- Tune the reso head first--I find it more convenient to dial in the final note on the batter side.
- When tuning the reso head of a snare drum, (a) remove the snare wires or insert a stick between the wires and the hoop, and (b) if the snare bed is deep, back off the tension on the four lugs adjacent to the bed. I usually leave these lugs about 20Hz-30Hz lower than the rest of the lugs. This prevents the reso hoop from bending down into the bed and also allows for more contact between the snare wires and the head. Ideally, you want to tune snare drum resonant lug frequencies to a perfect fifth (1.5 times), perfect fourth (1.33 times), or major third (1.26 times) higher than batter lug frequencies, keeping in mind that Tune-bot recommends against exceeding 400Hz at the lugs with thinner (2-3 mil) snare side heads.
- Once you get a lug near the desired frequency, press the "Filter" button on your Tune-bot so it ignores overtones. Otherwise, Tune-bot may pick up overtones, which will cause varying frequency readings for the same lug at the same tuning. The Filter function is a huge help in screening out those "phantom" readings. This takes a bit of practice--if you are tuning a lug to 220, and you believe you are close but Tune-bot is reading 205 on one hit and 130 on another, press "Filter" the next time you get a reading near 205. I use the "Filter" function on the way up to the desired frequency as well to check for consistent tuning across the lugs.
- When tuning larger drums, you will have to move the Tune-bot closer to the lug you are tuning--I've found that I can't leave the Tune-bot in one position on the hoop when working my way around larger drums. With drums up to 14" in diameter that are close to the desired tuning, I usually tune half the lugs from one Tune-bot position, and then I move the Tune-bot to the opposite side of the drum and tune the remaining lugs. With 16" and larger drums, I usually hold the Tune-bot directly above the head at each lug.
- When checking the overall note of a drum, be sure you are not touching either head or putting tension on a hoop and accidentally altering the note--if practical, place the drum on a stand. Then, hold Tune-bot over the center of the batter head and hit the drum. Tune-bot will return the overall frequency or note (you can toggle between the two readings using the "Note" button). If you are checking the drum close to other drums, sympathetic vibrations could throw off your readings. When possible, check each drum's note away from other drums, or muffle the nearby drums.
- Remember that each drum shell resonates within a limited frequency range. If you tune the drum outside that range--too high or too low--the drum will sound "choked." The fundamental note of the shell is the frequency that generates maximum shell resonance. DW actually stamps the fundamental note on the inside of each of its shells, but you can hear it by tapping the shell in a quiet room with the hoops and heads removed.
- As always, be careful with your bearing edges! It's all too easy to ding an edge when changing out heads. Uneven bearing edges are a common culprit behind tuning difficulties and poor tone.
A Note About Seating
The actual seating process is something like performing drum "CPR"--pressing your palms down on the center of a drumhead and performing two or three "compressions." In my experience, moderate seating of new drumheads does help them remain in tune after playing and will help bring the tone of the drum shell into the mix. Whether seating is necessary or not depends on the specific combination of drumhead and drum. I have found that Remo heads typically require seating, while Evans heads often tune up initially and stay in tune without the seating step. The improved collar design on the new Evans 360 heads seems to reduce the need for seating even further. However, some drums, such as my Ludwig Acrolite snare drum, require attention to seating regardless of the make of the drumhead in order to achieve the bearing edge contact necessary for the shell to sing!
Snare heads are too thin to seat--they could be damaged by the seating process. To seat any other batter or resonant head, first, bring it up to an even, medium tuning, and place the drum on something flat and sturdy--I usually use the floor. Then, spread the palm of your hand across the center of the head, rest your other hand on top of the first, and perform two or three downward compressions, using the weight of your upper body. Always use your palm--not fingertips, knuckles, etc.--so you do not direct too much weight to any one point on the head. Also, take care to prevent watches, bracelets, and rings from coming into contact with the head. Some of the glue in the drumhead collar, especially with Remo heads, may "pop" and "crackle" as you place weight on the head--this is expected. I do not recommend standing on the heads of larger drums as some suggest. Seating compressions can de-tune both drumheads--the top head, of course, but the bottom hoop can press upward as well, stretching the bottom head slightly--in that case, you will need to tune both heads back up to the desired note. Don't be afraid to repeat the process to obtain the bearing edge contact necessary to bring out the drum shell's tone.

Other Tuning Resources
After using Tune-bot for a while, I thought it would be cool to see other drummers' Tune-bot settings, and when I searched for them on the web, I ended up at Tune-bot's site. Check out http://tune-bot.com/drum-tuning.html. This page provides great information on overall notes for various drums, and offers tuning approaches for toms, snares, and bass drums. Tune-bot's lug frequency calcs were off a bit, at least for my kits, so I've shared the "street" lug frequencies I've worked out over the past several months to achieve the desired overall notes.
Be sure to check out http://tune-bot.com/artisttuning.html for several pro tuning schemes. Also, you can find Tune-bot threads on many of the major online drumming forums, although you may have to sift through posts from drummers who are new to Tune-bot and haven't gotten the hang of it yet.
Last but not least, if you want a deeper understanding of the physics behind drum tuning, check out The Physics of Overtones at circularscience.com.
Take the time to get used to tuning your drums with Tune-bot. Once you hear the amazing tone your kit can produce with properly tuned drums, you will enjoy playing them more--and you will stop drooling over that DW kit you've had your eye on.
