The RockBoard Stage Tuner V2 is a chromatic pedal tuner, the StageTuner ST-01, built to sit on a pedalboard and give a clear pitch reading at a glance. RockBoard's PedalPedia describes it as combining all the aspects musicians seek in a chromatic pedal tuner, and its most prominent feature is the display: a large, bright 28-segment LED readout that RockBoard's PedalPedia says provides an easily readable interface even from meters away, bright enough to read on a dark stage without being blinding.1

Display and tuning on stage
A tuner's job on a pedalboard is to be read quickly and from a distance, and that is where RockBoard puts its emphasis. The 28-segment LED display is described as large and bright but not blinding, readable from meters away, which suits players who tune while standing back from their rig or in low stage light.1
The pedal also covers ensemble situations where standard pitch is not a given, since its reference frequency can be adjusted so it can follow a piano or an ensemble tuned slightly off standard pitch.1
What the maker highlights:
- Large, bright 28-segment LED display, readable from meters away1
- Bright enough for a dark stage without being blinding1
- Adjustable reference frequency for ensemble playing1
- Two outputs for silent or audible tuning1
Silent or audible tuning
The Stage Tuner V2 has two outputs, which RockBoard says allow for either silent or audible tuning. In practice, that means you can route your signal so the amp is muted while you tune, or leave it live and tune audibly between songs.1
Bypass and signal path
The pedal uses true bypass switching. RockBoard's PedalPedia states that the true bypass does not affect your guitar's tone at all, so when the tuner is switched off your signal passes through unchanged.1
RockBoard's PedalPedia lists the circuit type as analog.1
Power
The Stage Tuner V2 runs on 9V DC, center negative, and draws 22mA of current.1
The pedal draws 22mA, so it needs its own current-limited output on most pedalboard power supplies rather than a shared low-current tap.
How it compares
The Stage Tuner V2 sits in a crowded field of chromatic pedal tuners, alongside units like the Boss TU3 Tuner and the Peterson StroboStomp HD. RockBoard's PedalPedia describes it as a compact pedal, built in a metal housing, and lists it as available in the shop.1

Questions
Is the RockBoard Stage Tuner V2 true bypass?
Yes. RockBoard states the Stage Tuner V2 uses true bypass switching, and says the true bypass does not affect your guitar's tone at all. When the tuner is off, your signal passes through without any change, which matters on a pedalboard where the tuner sits in the main signal path.
What power supply does the RockBoard Stage Tuner V2 use?
The Stage Tuner V2 runs on a 9V DC supply with a center negative plug and draws 22mA of current. It has no battery option mentioned, so plan for a standard pedalboard power supply output or a dedicated 9V adapter.
Can the RockBoard Stage Tuner V2 tune silently?
Yes. The pedal has two outputs, which RockBoard says allow for either silent or audible tuning. Sending only the second output to your amp or tuner path lets you tune without the audience hearing the note.
What reference pitches can the RockBoard Stage Tuner V2 use?
The reference frequency can be changed in 1 Hz steps from 432 to 445 Hz. Standard concert pitch of 440 Hz sits within that range, and the adjustment is useful when playing with instruments tuned to a different reference, such as a piano or an ensemble set slightly sharp or flat.
Is the RockBoard Stage Tuner V2 analog or digital?
RockBoard lists the circuit type as analog. That describes the signal path through the pedal; the display itself is a 28-segment LED readout that shows pitch visually.
