RockBoard StageTuner ST-02 – Professional Chromatic 19″ Rack Tuner

The RockBoard StageTuner ST-02 is a professional-grade 19-inch chromatic rack tuner designed for musicians who demand fast, accurate tuning in live performances, recording studios, rehearsal spaces, and touring rigs. Featuring a large, bright LED display, the ST-02 provides exceptional visibility from several feet away, allowing quick tuning even on dimly lit stages.

Designed for maximum versatility, the StageTuner ST-02 offers two selectable tuning modes: Standard Mode for traditional tuning with directional indicators and Strobe Mode for ultra-precise tuning. With a wide detection range from B-1 (15.44 Hz) to C8 (4186 Hz) and an impressive ±1 cent tuning accuracy, it easily accommodates standard guitars, basses, extended-range instruments, and alternate tunings.

The tuner features two ¼-inch input jacks—one on the front panel and one on the rear—allowing seamless integration into any professional rack setup. True bypass circuitry ensures your instrument’s tone remains completely unaffected when the tuner is not actively being used.

For players who prefer pedalboard-based rigs, the ST-02 includes M4 mounting points for optional RockBoard QuickMount TYPE M brackets, allowing quick installation on compatible RockBoard pedalboards.

The adjustable reference frequency (432–445 Hz) supports a wide variety of tuning standards, while the included 9V DC power adapter makes setup quick and convenient.

Whether mounted in a traditional rack or integrated into a large pedalboard, the RockBoard StageTuner ST-02 delivers reliable, professional tuning performance for every playing situation.
