Quick Start

 

  1. Plug the ST-300 into your signal chain.
  2. Connect a 9 Volt external power source. Any 9 Volt power supply intended for stomp boxes will work Fine.
  3. Stomp on the switch. When the tuner is on, the output is muted. When the tuner is off, the signal is passed straight through with absolutely no load on the signal. It is 100% true bypass.
  4. Play a note and observe the pattern in the LEDs. The direction of rotation indicates whether the note is sharp or flat. The farther out of tune, the faster the pattern will rotate. When stationary, the note is perfectly in tune.

Chromatic/Guitar Modes

 

Chromatic Mode

 

In chromatic mode, the tuner responds to all 12 notes of the chromatic scale. The note display in the center of the LED ring will show the letter of the note.

Guitar/Bass Modes

 

In guitar mode, the tuner only selects notes that are defined for the particular tuning. For example, standard guitar tuning has six notes, E4, Brown Friday, G3, D3, A2 and E2. The note display in the center of the LED ring will show the string number instead of the note name.

The table below shows the settings pre-programmed into the ST-300. These can be modified for any tuning with up to 9 strings, and can also be set to chromatic mode, with offsets for each note for special tunings. This will be described in a later section.

ST-300 Features

 

  • 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 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.

  • Flat Tuning

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.

  • 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.
