The Hotone Harmony is a compact digital pitch-shifter and harmonist pedal designed for electric guitar and bass, made by Hotone as part of the brand's ultra-mini Skyline series. Its circuit features polyphonic pitch processing capable of tracking full chords and single-note leads, which puts it in the same family of pedals as other polyphonic shifters listed under Octave & Pitch Pedals. Hotone has since discontinued it, listing the Harmony on the discontinued-products section of its own site1.
What it does and how it is controlled
A toggle switch selects between three distinct modes, and two knobs balance the dry and shifted signals1:
| Mode | What it does |
|---|---|
| Pitch Shift | Shifts pitch in semitone steps |
| Detune | -25 to +25 cents for chorus-style widening |
| Pitch Down | Pitch shifting downward |
Direct tone control comes from dedicated knobs that balance the dry signal against the pitch-shifted output level, so you can run the effect behind your clean tone or push it forward1. That dry/blend arrangement is the usual way players use a polyphonic shifter on a board: keep the dry signal at full and bring the shifted voice in underneath for thickness, or mute the dry side for a full shift.
The Detune mode works in cents, the fine division of a semitone, spanning -25 to +25 cents. Applied to a copied voice, that spread is what produces a chorus-style widening effect rather than a distinct second note1.
Build and power
The enclosure is a zinc alloy body with a protective top bar and an illuminated central control knob, in keeping with the Skyline series' small footprint1. Power is 9V DC, center negative, at a 53mA draw1.
The Harmony is discontinued. RockBoard's PedalPedia lists it on the discontinued-products section of its website, so current production Hotone pitch pedals, such as the Hotone FreqLux, sit in newer product lines1.
How it compares
Polyphonic tracking is the Harmony's headline feature: because the processing handles chords, not just single notes, it can be used on rhythm parts as well as leads1. Other makers approach the same job in different ways. The Electro-Harmonix Intelligent Harmony Machine is a digital harmonizer and pitch shifter whose Polyphonic Override mode performs what Electro-Harmonix describes as perfect polyphonic pitch shifts applied to chords as well as single notes2. A smaller version, the Electro-Harmonix Pico Intelligent Harmony Machine, is also a digital circuit3. Where the Harmony keeps its controls to a mode toggle and two level knobs, those pedals add intelligent harmony features aimed at generating matching harmonies to what you play2.

Questions
Is the Hotone Harmony true bypass?
Yes. The Hotone Harmony uses true-bypass switching, so when the pedal is off, your guitar's signal passes through without the pitch-shifting circuit in the way. That matters on a pedalboard where a pitch pedal can otherwise load down your clean tone.
Is the Hotone Harmony analog or digital?
The Hotone Harmony is a digital pedal. Its circuit uses digital polyphonic pitch processing, which is what allows it to track full chords and single-note leads rather than only single notes.
What power does the Hotone Harmony use?
The Hotone Harmony runs on 9V DC, center negative, and draws 53mA. Like most compact digital pedals, it needs a standard center-negative supply, so check that your daisy-chain or isolated power supply can supply the current.
Is the Hotone Harmony still in production?
No. Hotone lists the Harmony among its discontinued products. It was part of the brand's ultra-mini Skyline series, and used units remain the way most players encounter it.
Does the Hotone Harmony work with chords?
Yes. Hotone describes the Harmony's circuit as polyphonic pitch processing capable of tracking full chords as well as single-note leads, so you can shift or harmonize chord progressions, not just melodic lines.
