The famed Turbo Tuner has finally arrived and it's smaller than ever! Features include customisable presets, and EXTREMELY FAST (zero latency/tunes to note instantly) & ACCURATE tuning primarily because it is a true strobe unlike digital tuners from Korg and TC Electronic.
MORE INFO 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.
Extreme Accuracy: The internal timing generator is calibrated at the factory to maintain a precision of ±.02 cents.
Chromatic Mode: 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 recognises 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.
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.
Temperaments: 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.
Flat Tuning: Flat tuning lowers the pitch of all notes below the regular tuning from one to six semitones. To change the number of flats, hold the FLAT button while turing the tuner on. The Flat LED will flash, and the note display will show the number of flats. Pressing the FLAT button will advance the number of flats. Pressing the CAL key will save the number of flats and return to normal operation. When the number of flats is anything other than zero, the Flat LED will be illuminated.
Changing the Reference Pitch: The default reference pitch is A4=440 Hz. This can be changed in .1Hz increments to any value from 300.0 Hz to 599.9 Hz. To change the reference pitch, press the CAL button while turning the tuner on. The A4 LED will flash, and the current setting of A4 will scroll through the note display.You then press the CAL button to scroll through the current setting, and use the FLAT button to change each digit. After the desired value has been entered, press the CAL button until the note display is blank, and press the FLAT button. The tuner will now resume normal operation. Whenever the A4 reference is set to anything other than 440.0 Hz, the A4 LED will be illuminated. The
Clear Key: Holding down both buttons while turning on the power will have the following effect: The A4 reference frequency is set to 440Hz. Any flats are cleared.
