Overtone Labs is a Denver, Colorado-based company that designs digital tuners for drums. Founded around the introduction of its first product in 2012, the company specializes in clip-on devices that measure drumhead frequency and pitch, filter out overtones, and help drummers achieve consistent tuning across lugs and across kits.

The brand is best known for its tune-bot product line. The original tune-bot established the category of dedicated digital drum tuners, and the lineup has since expanded to include the tune-bot Gig, a simplified single-button model aimed at quick stage and rehearsal use, and the tune-bot Studio, which extends the frequency range up to 450Hz for tuning smaller toms and snares and adds a multi-color display and streamlined keypad. The tuners measure in both Hz and musical notes and include features for storing tunings and fine-tuning by ear or by reference pitch.

The products have been reviewed in outlets such as Modern Drummer, Sound on Sound, and Tape Op, and are carried by major retailers including Sweetwater, Reverb, Thomann, and Sam Ash. Overtone Labs has positioned the tune-bot as a tool for both touring drummers and studio engineers looking for repeatable, measurable drum tuning.

Overtone Labs has 1 product cataloged on Equipboard, including Drum Set Accessories. Their gear is featured by 3 artists, with the strongest followings in Rock, Metal, and Folk, World, & Country. Notable users include Trey Williams, Rich Redmond, and Ian Roberts.
