Pitch Correction With Your Guitar

The VoiceTone C1 can be controlled via guitar input if desired, ensuring your pitch correction will match the instruments. The key can also be set manually. The other controls adjust the level of attack, from subtle correction up to the jagged HardTune effect, and the gender manipulation, from male / deep to female / alien gender.

Easy To Use

Using the VoiceTone C1 is as simple as plugging in your mic and turning the effect on. As soon as you do you'll have access to the studio-quality sounds and intelligent processing, and changing the style or the amount of effect is easy thanks to the simple, straightforward controls.

Built-In Pro-Quality Mic Preamp

The VoiceTone C1 also features a pro-quality, quiet mic preamp with phantom power that rivals high-end touring mixers, and a recessed mic gain to prevent accidental bumps on stage. A USB connector allows you to hook the pedal up to your computer and access the VoiceSupport application, offering tips, tricks and updates.

Remote Control

The Mic Control circuit built into the pedal allows you to control the pedal using the TC Helicon MP-75 Modern Performance Vocal Microphone (also available at Gear4music). The thumb switch on the microphone allows you to turn the pedal effect on and off without having to look down at your feet, giving you far greater freedom to work the stage.
