Presenting the Sonic Research ST-300 Mini Stomp Box Strobe Tuner Pedal.
The ST-300 Mini is designed to respond quickly to the notes from your guitar without resorting to adjusting the volume or plucking the string differently than you normally would when playing.
True Strobe Display
Easy to read display instantly shows the slightest difference in pitch of the note played from the indicated note. The ring of LEDs is a true stroboscope, driven directly by the analog input signal and a precision internal frequency reference. This gives zero latency and instantly shows the slightest tuning error.
True Bypass / Muted Output
The output of the ST-300 is muted when the tuner is on, and when off the input signal is passed directly to the output. It is completely disconnected from all internal circuitry and the tuner puts zero load on the signal.
The internal timing generator is calibrated at the factory to maintain a precision of ±.02 cents.
Permits tuning to any of the 12 notes from C0 to C8, in any temperament.
Open Tuning Modes
Tunes to preset or user defined tunings. In this mode the tuner only recognizes notes that are defined for the specified tuning. The tuner comes with a number of pre-defined tunings for stringed instruments. These can be edited by the user.
Power On Restore
The ST-300 remembers the settings for mode, drop tuning and A4 changes. No battery is necessary.
Lowers all pitches up to six semitones.
Reference Pitch Change
By default, the tuner uses A4=440Hz as the reference pitch. This can be changed in increments of .1Hz, over the range of 300.0 Hz to 599.9 Hz.
The ST-300 can operate in the equal temperament or any 12 note temperament the user desires. The ST-300 can store a total of 5 different temperaments, in addition to the equal temperament.
External 9 Volt Operation
The Turbo Tuner ST-300 Mini operates from an external 9 Volt adaptor. Any 9 Volt adapter designed for stomp boxes will work fine.
