From the wildly popular HardTune effect to subtle pitch correction and gender manipulation, the VoiceTone Single C1 brings the infamous pitch correction effect to the stage.

Mild to Wild Pitch Correction Processing
VoiceTone C1 has clean, transparent correction capability with unique control of musical input via the guitar input if desired. When transparency isn't your bag, cranking the attack and gender controls will turn the C1's pitch correction into the robotic modern effect heard everywhere.

As simple as plugging in your mic
Gaining access to the studio quality sounds and intelligent processing of the VoiceTone C1 is as simple as plugging in your mic and turning the effect on. Of course, you can always change the style or the amount of effect, but you shouldn't need to unfold the manual.

Strong family genes
The TC-Helicon VoiceTone Singles series includes four vocal processing pedals, each with a single mission - to allow any vocalist to deliver jaw-dropping performances. VoiceTone Singles are the ultimate combination of tone and simplicity. Each of the four effects has inherited algorithms from the award-winning VoiceLive 2, so although VoiceTone Singles come in small packages they deliver a big sound.

    Interesting but...

    By Alan Lebov

    Comments about TC Helicon VoiceTone Single C1 HardTune & Correction:

    Instead of just altering the pitch it seems to split it into pitch corrected and original and then output them as a "doubled" voice. I really found this doubling quite artificial and frankly annoying. Choosing less correction just made the doubling fade in and out which was even worse in my opinion. I finally just returned the unit.

    Comments about TC Helicon VoiceTone Single C1 HardTune & Correction:

    I tend to be slightly pitchy vocally, so when this pedal was recently released, I was one of the first to purchase one. My primary interest is the pitch correction and not the other effects. Unfortunately for me, the pitch correction aspect of this pedal has been a disappointment. It will correct only very, very minor pitch issues. When I sing into it intentionally off key, it is is simply unable to correct the problem. Setting the pedal to chromatic or to the specific key, does not seem to make a difference, nor does plugging an instrument into the pedal for key assignment. The built in pre-amp is quite useful as is the phantom power. The pre-amp is clean and crisp and offers substantial gain when used with my Blue condenser mic. As far as the effects go, they can be used to "warm" the voice or make a voice sound more masculine or feminine. When fully cranked, they produce an alien voice which is of no interest to me. Cranking the pitch correction knob to full creates a fun sound best described as delay with pitch shift: an interesting effect of limited usefulness. In summary, the C1 does help slightly with pitch issues, has a useful pre-amp, phantom power, and effects of limited usefulness. Worth the price? ... probably not to me, but a better singer than I may well disagree.
