The GoGo Tuners Caliber is a chromatic pedal tuner, the company's second stompbox offering after it had made its name with a range of clip-on tuners1. It debuted at NAMM in January 2015 with a calibration mode, tighter tuning accuracy and a high-definition screen2. What sets it apart from most tuner pedals is the size of that display: it takes up about 75 percent of the top surface, giving the pedal the look of a chunky smartphone1.
The tuner uses chromatic tuning with +/-0.5-cent accuracy and a wide detection range of A0 (27.5 Hz) to C8 (4186.00 Hz), which covers everything a guitar or bass can produce and well beyond23.
The display and how you read it
The high-definition big screen is easily visible in all lighting situations, according to MusicRadar's report from the pedal's debut2. Premier Guitar's reviewer went further, calling the display the pedal's defining feature: large flat and sharp indicators and big block-letter note names, with everything that illuminates on the display turning from red to green when you hit your desired mark1.
"Solid and accurate. Massive easy-to-read display."
The reviewer's verdict was that the exceptional display warrants special consideration on display and accuracy alone1.
Controls and calibration
The pedal keeps its controls simple. A durable stomp knob handles switching3, and a calibration push-button on the left side permits easy scrolling through reference pitches from 430 Hz to 450 Hz1. That calibration range lets you match instruments tuned to reference pitches other than the standard A440, which MusicRadar noted allows tighter tuning2.
| Control | What it does |
|---|---|
| Stomp knob | Switches the tuner in and out3 |
| Calibration push-button (left side) | Scrolls through reference pitches from 430 Hz to 450 Hz1 |
Power and your pedalboard
The Caliber runs on a 9V Boss-style adapter, which is not included, and battery power is an option1. It also provides daisy chain power for other pedals, so it can feed power to the rest of a small board from one supply2.
The power adapter is not included with the pedal1. If you plan to run other pedals from the Caliber's daisy chain output, budget for a supply with enough current for the whole board.
Build and where it came from
The pedal features a metal chassis for improved durability and longer lifetime performance2. Premier Guitar describes a sturdy metal enclosure with a gunmetal-gray finish that gives it a stealth demeanor1.
The Caliber is GoGo Tuners' second stompbox, following the company's earlier clip-on tuners1. It carries the maker's chromatic tuning in a sturdy metal enclosure with a gunmetal-gray finish13. At introduction it carried a street price of $991.

Questions
Does the GoGo Tuners Caliber run on a battery?
Yes. Premier Guitar's review notes that battery power is an option on the Caliber, alongside the 9V Boss-style adapter. The adapter itself is not included with the pedal, so you need to supply your own power supply or batteries.
Is the GoGo Tuners Caliber true bypass?
Yes. GoGo Tuners lists true bypass among the pedal's features, and both Premier Guitar and MusicRadar confirm it. When the tuner is switched off, your signal passes through without the pedal's circuitry in the chain.
Does the Caliber power other pedals?
Yes. MusicRadar reported at the pedal's NAMM 2015 debut that the Caliber provides daisy chain power for other pedals, so it can act as a power source for the rest of a small pedalboard.
What is the calibration range of the GoGo Caliber?
The reference pitch can be calibrated from 430 Hz to 450 Hz. A push-button on the left side of the pedal scrolls through the reference pitches, which lets you tune tighter to instruments fixed at pitches other than standard A440.
Does the GoGo Caliber come with a power adapter?
No. Premier Guitar's review describes running the pedal on a 9V Boss-style adapter that is not included. You will need to use your own adapter, or the battery option, when you set the pedal up.
