• 2 Voices of realistic sounding vocal harmonies with 8 different styles
  • Set key manually or auto-detect key/scale effortlessly from guitar input
  • Chain it with other VoiceTone Singles to create your perfect sound
  • Mic-ControlTM for remote on-off with TC-Helicon’s MP-75 microphone


This is simply the most natural sounding & affordable vocal harmony processor you’ll find.  Choose one or two voices in a variety of harmony styles above and/or below your lead vocal.  Getting it started is simple: guitar players can plug right in and behold the auto-key sensing magic. Otherwise, just set the key and start singing.

Watch it Work

The incredibly gifted Andy Allo uses the H1 on her cover of the Arctic Monkeys’ “Do I Wanna Know.” Then, Craig Fraser shows how H1 works its magic in tandem with the VoiceTone T1 and R1 pedals.


It's just this simple

  • Plug in your mic, plug your pedal into the mixer & set gain.
  • Select the harmony style.
  • (That’s it.)

Of course, you can always change the style or the amount of harmony, but you shouldn’t need to unfold the manual unless you’re making a fire.


Chain it.

You can chain H1 to all of the other VoiceTone Singles, mixing and matching effects to define your personal sound. It also works with Ditto Mic Looper, the pure looping pedal for singers and instrumentalists. Use the Singles Connect Kit to mix and match up to 4 TC-Helicon vocal effect pedals together conveniently, simply and with less cable clutter than ever before.

Under the hood

Beneath the sturdy, die-cast metal case, you’ll be getting the same quality processing you’d expect from our flagship VoiceLive® vocal processors. You’ll also find a clean, quiet mic preamp that rivals high-end touring mixers & studio quality analog to digital conversion. There’s even a USB connection for firmware updates.



  1. Create harmonies simply by selecting your key or plugging in your guitar.
  2. Add harmonies above, below, close, far and in combination.
  3. Precise control of the exact level of your harmony.
  4. Dedicated on-off footswitch. H1 Also comes with USB connection for updates.

More Mic, more control

Roam the stage while completely controlling H1 from your mic. Simply plug in an MP-75 microphone or the Sennheiser e835 FX. We call it Mic Control™ and because of it, you command both the stage and the audience.

What They Say...

"Seriously, the box rocks and the price rocks even harder. It even tracks the key your guitar is in when you play so no worries on tuning down, changing keys when you are a little hoarse... you name it!"

-Ken Tamplin, Renowned Vocal Coach

"This little piece of magic is now a mainstay in my acoustic covers duo. It adds such dynamic depth to the songs we play. Worth the price paid and would buy another in a heartbeat."

-Customer, USA

"VoiceTone Singles are the ultimate combination of tone and simplicity. They’ve inherited algorithms from the award-winning VoiceLive 2, so although VoiceTone Singles come in small packages they deliver a big sound."
