TC-Helicon VoiceTone Harmony-G XT



Harmonies and effects made easy for guitarists.

Kick your vocals into high gear with VoiceTone Harmony-G XT. With improved harmony technology and reverb compared to its big brother VoiceLive 2, Harmony-G XT will improve your tone and surround your voice with pro effects and vocal harmony.

Easy Harmony Generation

The TC Helicon Harmony-G XT has a good ear for music. It listens to your performance and decides what harmony notes would sound best with your song. Connect your guitar and a mic, choose one of the presets, play guitar and sing. No special guitar pickups, pre-programming, or extensive musical knowledge are required in order to use this vocal harmony effect pedal.

Choose Your Sound

The TC Helicon Harmony-G XT puts you in control of a wide range of useful, exciting sounds. From a standing position you can switch through the five factory presets, each with a unique setting of effects, harmony and doubling and then choose the A or B effect within each preset. If you only need three presets or you want up to ten, this is configurable in Harmony-G XT.

The effect pedal lets you edit the presets easily and store them as your personal combination. The "FX" for each preset can be selected as well. Each of the categories of Hall, Room, Echo, Slap, Combi and SFX has three alternates. These are more than just add-on effects. These are the real deal from VoiceLive 2 including combinations of reverb, delay andµmod (micromod) that will put you and your harmony voices in a professional sounding, immersive space.

Overdub Live

In a recording you can layer your lead melody to create extra thickness. Live, it's not so easy. The Double button on the vocal harmony pedal activates a realistic, overdub style doubling effect on your voice that you can use alone or in tandem with the harmony voices. You have four options for doubling you can choose from: The default one voice with tightest humanization, one voice with looser and more natural humanization, two tight voices, and two natural voices.

Better Overall Tone

Don't let that simple-looking Tone button fool you. Beneath is a professional signal chain. It includes such settings as Adaptive Shape, a unique boom reduction and brightness enhancer, Compression for smoothing peaks and gently raising low level detail, De-ess, which reduces harsh consonant sounds, Adaptive gate, which helps to reduce feedback while reducing harmonized chattering of instruments when you're not singing.

Once Tone is activated, the TC Helicon VoiceTone Harmony-G XT remains in effect when harmonies are on and off and even in Bypass so you can chat with your audience using the same great tone as when you sing.

Connect To Your Computer

The TC Helicon Harmony-G XT has a USB connection and a free, included web applet called VoiceSupport. It offers easy backup and restore of your presets to a computer, fast product registration and up-to-date news on software updates, and tips and tricks along with demo videos.
