Pedal Sonic Research Turbo Tuner ST-300

The ST-300 Turbo Tuner is our top choice among pedal tuners. Featuring ±0.02 cent detection accuracy, a super-wide calibration range, outstanding low-note detection, programmability, and a bright true stroboscopic display with near-instantaneous response, it’s a seriously brilliant piece of gear. It’s also made in US.
