TC HeliconVoiceTone Single H1 Intelligent Harmony Effects Pedal
1/4
Independent shopping perspective
The Korena take
A single-purpose vocal harmony pedal with an XLR mic input and a guitar input for key tracking. For singing guitarists who want harmonies live.
Strong match
Who this is for
- Solo acoustic performers adding a harmony line to a chorus
- Duos that want a third vocal part without a third singer
- Singers who need harmonies on a footswitch, not a laptop
Consider the trade-offs
When to look elsewhere
- Players wanting pitch correction, reverb or doubling in one box
- Keyboard or non-guitar acts, since key tracking comes from the guitar input
- Anyone needing multiple stacked harmony voices
What matters in use
The specifications, translated
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 02
Guitar input, 1 megohm impedance
Takes a guitar or piezo pickup directly and reads your chords to pick harmony notes in key.
Detail 03
Balanced XLR output, 200 ohm
Runs a long cable to the front-of-house snake without hum or level loss.
Detail 04
12V 0.4A supply included
It will not run off a standard 9V pedalboard chain; budget a spare outlet or dedicated 12V tap.
Detail 05
Mic input handles -42dBu to +1dBu
Copes with a quiet talker and a loud belter on the same gain setting without clipping.
Detail 06
0.92 lb, 3.5 x 5.4 inches
Small and light enough to velcro to a board, but taller front-to-back than a standard stompbox.
Final check
Know before you order
- 01No mic, XLR cables or guitar cable included
- 02Harmony follows the guitar input — no guitar plugged in means no key reference
- 03The 12V supply takes a full wall outlet or a 12V pedalboard output
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Do I need a guitar plugged in for it to work?
The guitar input is how it determines your key. Without a chord source feeding it, it has nothing to derive harmony notes from.
02Can I run it on a 9V pedalboard supply?
No. It ships with a 12V 0.4A supply and needs that voltage.
03Can I plug a microphone straight into it?
Yes. It has an XLR mic input with its own preamp, and a balanced XLR out to the PA.
04Does it do reverb or pitch correction too?
It is the harmony member of the VoiceTone Single line — one effect per pedal.
