The BOSS TU-3 Chromatic Tuner Pedal unites trusted BOSS tuning technology with iconic compact pedal format. Top performers everywhere rely on this robust stomp for fast and flawless tuning night after night, thanks to its high-visibility meter, simple operation, and road-tested durability. The versatile TU-3 also includes a mute function, tone-saving buffer, and power distribution capabilities, making it an essential utility tool for every player. Precision Tuning Made Easy The TU-3’s sharp, 21-segment LED meter takes the guesswork out of tuning, offering both Cent and strobe-style Stream options for your preference. The innovative Accu-Pitch Sign function speeds operation on stage by displaying a bright streaming indicator when you’ve reached your target. The default Chromatic mode automatically detects any incoming pitch, while selectable guitar and bass modes provide quick, string-based tuning with support for extended-range instruments and down tunings. Pitch-Perfect Performance The TU-3 packs a ton of practical features into its compact size. Engaging the pedal activates a mute function, allowing you to tune silently and keep your rig quiet during instrument changes and set breaks. High brightness mode cuts through glare for improved meter visibility on sunlit outdoor stages and when powering the TU-3 with an optional PSA-series adapter, you can use a PCS-20A parallel cable to distribute power to other pedals on your board.
