TC HeliconVoiceTone Single D1 Doubling & Detune Effects Pedal
1/4
Independent shopping perspective
The Korena take
A single-purpose vocal pedal that adds doubling and detune to a live vocal. For singers who want a thicker lead voice without a full harmony processor.
Strong match
Who this is for
- Solo performers wanting a fuller lead vocal live
- Singer-guitarists running one box for both signals
- Small stages where a rack processor won't fit
Consider the trade-offs
When to look elsewhere
- Anyone needing harmonies, pitch correction or reverb
- Studio users who already have doubling plugins
- Singers wanting multiple effect types in one pedal
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
Separate guitar input
Guitar passes through at 1 megohm, so a passive pickup keeps its top end while your vocal gets processed.
Detail 03
Balanced XLR output
Runs long cable to front of house without picking up hum. Send this to a mixer channel, not a guitar amp.
Detail 04
Mic input range −42 to +1 dBu
Handles quiet dynamic mics and loud belted vocals. Set gain so peaks land near the top without clipping.
Detail 05
Doubling and detune only
Widens and thickens one voice. It does not create harmony notes or correct pitch.
Detail 06
5.4 x 3.5 inches, under a pound
Small footprint on a pedalboard, but light enough that stiff XLR cables can drag it around. Velcro it down.
Final check
Know before you order
- 01Needs a mixer or PA with an XLR input — not an amp-only setup
- 02Check whether your mic requires phantom power from this unit or the board
- 03No mic, cables, or power supply are part of the pedal itself
Product questions
Before you decide
Straight answers to the questions shoppers most often ask about this product.
01Does it do harmonies?
No. It doubles and detunes your own voice to thicken it. For added harmony notes you need a different VoiceTone model.
02Can I use it with a condenser mic?
Only if phantom power is available. Confirm the pedal supplies it or run the mic through a board channel that does.
03Will it work on guitar too?
The guitar input is a clean pass-through with high input impedance. The doubling effect is applied to the mic signal.
04Can I use it for recording?
Yes, into an interface with an XLR input. The effect is printed to the take, so you can't undo it later.
