RockBoard StageTuner ST-02 - Chromatic Rack Tuner
The RockBoard StageTuner ST-02 offers all the features that musicians want in a chromatic rack tuner. The large, bright, but not blinding LED display offers an easy-to-read surface that is clearly visible even from a distance of several meters. The true bypass doesn't affect the sound of the connected instrument and with two inputs (one on the front and one on the back), the StageTuner ST-02 can be flexibly integrated into any rack. The calibration range frequency of the ST-02 can be set in 1 Hz steps from 432 to 445 Hz and the large detection range from B-1 (15.44 Hz) to C8 (4,186.0 Hz) also covers extended range instruments or lower tunings easily. In addition to the standard mode, in which the arrows on the left and right in the display show the tuning direction, the StageTuner offers a strobe mode. Besides the standard installation in a 19" rack, the StageTuner can be mounted quickly and easily on a RockBoard pedalboard with the RockBoard QuickMounts TYPE M (available separately). All of this makes the StageTuner ST -02 a perfect choice for the stage, studios, rehearsal rooms and basically any other conceivable application.

Only affordable Rack Tuner that goes down to 432Hz

21 Jul 2023

I purchased this Warwick Rockboard ST-02 Rack mount tuner because I was hired by a band that plays at 432Hz. This tuner is the ONLY -$200 rack mount tuner that goes down to 432Hz. The next up is $400+! There is no on/off switch, so if you are mounting it for studio use, you'll have to install an in-line switch in the 12v power supply path. I was able to fit a latching LED pushbutton switch on one of the rack mount ears, effectively giving it an on/off switch that looks stock. That was the only gripe I had. Otherwise it's a perfectly functioning and very easy to ready tuner.
