The Monoprice Stage Right Chromatic Guitar and Bass Pedal Tuner is a chromatic pedal tuner for guitar and bass, sold under Monoprice's Stage Right brand. It sits on a pedalboard like any compact stompbox and tunes by note, across a range from A0 (27.5 Hz) to C8 (4186 Hz), which covers everything from a five-string bass low end to a guitar's highest fret. RockBoard's PedalPedia lists it as accurate to within plus or minus 1 cent1.
Outputs and muting
The pedal has two 1/4 inch TS outputs, Normal and Bypass, and they behave differently in a way that matters on stage1:
- Normal output: muted whenever the tuner is activated, so you can tune silently between songs.
- Bypass output: ignores the tuner completely and outputs whatever comes in over the 1/4 inch TS input jack, so signal keeps flowing there even while you tune.
That gives two placement options: mute the front of house while tuning, or keep a second amp or always-on path running through the Bypass output1.
Tuning and calibration
As a chromatic tuner, it detects any note in the scale rather than being locked to the six open strings. The tuning and reference specifications, as listed by RockBoard's PedalPedia1:
| Specification | Value |
|---|---|
| Tuning range | A0 (27.5 Hz) to C8 (4186 Hz) |
| Calibration range | 436 to 445 Hz |
| Calibration steps | 1 Hz increments |
| Detection accuracy | Within plus or minus 1 cent |
| Flat tuning support | 1, 2, or 3 flats applied to the tuning |
Calibration is adjustable in 1 Hz steps, so the reference pitch can be matched to a piano or ensemble that sits away from standard pitch1. For lower tunings, the pedal supports the application of 1, 2, or 3 flats to the tuning, which shifts the reference down for flat-tuned setups1.
Power and construction
The enclosure uses heavy-duty metal construction with an activation button designed to fit into a pedal rack, in Monoprice's description1. Power comes from either of two sources1:
- a 9V alkaline or heavy-duty battery, or
- a 9V DC power adapter with center negative polarity.
Batteries and power adapters are sold separately, so a 9V DC center negative adapter or a 9V battery must be supplied on its own1.
Where it sits among pedal tuners
The Stage Right tuner is a straightforward single-note chromatic pedal in a field that also includes polyphonic tuners such as the TC Electronic PolyTune 3, strobe-based pedals such as the Peterson StroboStomp HD, and compact tuners such as the Joyo Irontune. Its distinguishing features on paper are the dual outputs with independent muting behavior, the flat-tuning support, and the 1-cent accuracy figure.

Questions
Does the Monoprice Stage Right tuner mute the signal while tuning?
Yes, on one of its two outputs. The Normal output is muted whenever the tuner is activated, so the audience hears nothing while you tune. The Bypass output works differently: it ignores the tuner completely and passes through whatever comes in over the 1/4 inch TS input jack, so signal keeps flowing there even while the tuner is on.
Does the Monoprice Stage Right tuner come with a power adapter?
No. Batteries and power adapters are sold separately. The pedal runs on either a 9V alkaline or heavy-duty battery or on a 9V DC power adapter with a center negative plug, so you will need to supply one or the other yourself.
Is the Monoprice Stage Right pedal tuner analog or digital?
The circuit type is listed as analog on the product page carried by RockBoard's PedalPedia.
Can the Monoprice Stage Right tuner tune to flat tunings?
Yes. The tuner supports the application of 1, 2, or 3 flats to the tuning, so you can tune down in whole-step increments for drop or flat tunings without retuning by ear.
What is the calibration range of the Monoprice Stage Right tuner?
It can be calibrated to between 436 and 445 Hz in 1 Hz increments, so you can match the tuner to a piano, an ensemble, or a recording that sits away from standard 440 Hz reference pitch.
How accurate is the Monoprice Stage Right tuner?
Monoprice lists the tuner as accurate to within plus or minus 1 cent, which is a fine margin of error for a pedal tuner at any price.
