Overtone Labs is a Denver, Colorado-based company specializing in digital drum tuning technology. The company introduced its flagship product, the Tune-Bot, in 2012, bringing purpose-built electronic tuning to drummers in a category previously dominated by tension-measurement tools and tuning by ear. Tune-Bot devices clip to the drum rim and measure the fundamental pitch of each lug in both frequency (Hz) and musical notes, filtering out overtones to isolate individual tones for consistent head tensioning.

The product line includes the Tune-Bot Original, the single-button Tune-Bot Gig designed for quick use on stage, and the Tune-Bot Studio, which offers an expanded frequency range, a four-color display, and memory for multiple kits and drums. The tuners are commonly used by touring and session drummers to recall identical tunings across venues and recording sessions, and they are stocked by major retailers including Sweetwater, Thomann, and Sam Ash.

Overtone has 3 products cataloged on Equipboard, including Overdrive Effects Pedals and Distortion Effects Pedals.
