StageTuner ST-02 - Chromatic Rack Tuner

Everything in tune

The ST-02 Stage Tuner offers all the features musicians are looking for in a chromatic rack tuner. The large, bright but not dazzling, LED display provides an easy-to-read screen that is clearly visible from several feet away. True bypass has no effect on the sound of the connected instrument, and with two inputs (one on the front and one on the rear), the Stage Tuner ST-02 can be easily integrated into any rack. The frequency of the ST-02's reference tuning tone can be adjusted in 1 Hz increments from 432 to 445 Hz, and the wide tuning range from B-1 (15.44 Hz) to C8 (4,186.0 Hz) easily covers extended range instruments or low tunings. In addition to the standard mode, in which the arrows on the left and right of the display indicate the tuning direction, the Stage Tuner offers a strobe mode for tuning the instrument. If not used in a classic 19" rack-mounted configuration, the Stage Tuner can be quickly and easily mounted on a RockBoard pedalboard using the RockBoard QuickMounts TYPE M (sold separately) for use on large pedalboards, for example. All of this makes the Stage Tuner ST-02 a perfect choice for stage, studio, rehearsal room, and virtually any other application you can think of.
