The Sonic Research ST-300 Turbo Tuner is a high-precision strobe tuner designed for professional pedalboard and stage use. Its true strobe technology provides extremely fast pitch indication with guaranteed accuracy of ±0.02 cents, making it suitable for demanding setup, intonation and performance applications.
A bright LED display provides excellent visibility, while chromatic, guitar and bass modes accommodate a wide range of instruments. Programmable alternate tunings and temperaments offer additional flexibility, with reference pitch adjustable between 300.0Hz and 599.9Hz.
The ST-300 features pop-free true bypass and can mute the output while tuning or be configured to pass the instrument signal through. Its rugged stompbox enclosure is designed for regular pedalboard use and can be powered from either a 9V alkaline battery or compatible external 9V DC adapter.
