A Modern Rack Tuner Designed for Today's Rigs
The RockBoard StageTuner ST-02 embraces the simple and essential concept of a rack tuner: immediate readability, rock-solid reliability, and clean integration into a 19-inch system. What sets it apart is its very "field-oriented" approach: a large-format LED display that is bright without being harsh, a true bypass to avoid any unwanted coloration, and especially dual inputs (front and rear) that make life easier depending on your rack setup.
Designed to adapt to current configurations, it can also be mounted on a RockBoard pedalboard via a quick-mount system (sold separately) thanks to the mounting points provided on the back. The result: a versatile tuner that fits perfectly both in a touring rack and in a hybrid rack + pedalboard setup.
For Which Musicians and Use Cases?
The StageTuner ST-02 is aimed at guitarists, bassists, and anyone using an electric instrument requiring reliable and fast tuning. In rehearsal, it provides immediate comfort thanks to the screen's readability. On stage, it becomes a true "tuning control center": you can correct your pitch at a glance, even under challenging stage lighting.
Its very wide detection range (down to low frequencies) makes it relevant for low tunings, multi-string basses, and instruments with extended tessitura. In the studio, the adjustable calibration (A4) allows alignment with specific references (piano, acoustic instruments, orchestral standards) and ensures perfect consistency between takes.
