TC Helicon VoiceTone H1 Guitar-Controlled Vocal Harmony Pedal

TC Helicon VoiceTone H1 Guitar-Controlled Vocal Harmony Pedal

The TC Helicon VoiceTone H1 Vocal Harmony Pedal adds one or two harmony voices to a live vocal signal and can follow chords from a connected guitar or a manually selected musical key. Its single-foot-switch design, dedicated harmony controls, XLR microphone path, and compact enclosure make real-time vocal harmonizing practical for stage performance.

Singer-guitarists can route an instrument through the high-impedance input and thru connection so changing guitar chords guide the generated harmonies automatically. Vocalists can also select a song key directly when no guitar is connected. The Voices control places harmonies above or below the lead vocal with close and far interval combinations, while the Dry/Wet control balances the processed and original signals.

The VoiceTone H1 uses a balanced XLR microphone input and output for straightforward integration between a microphone and PA mixer. Phantom power is available whenever the processor is powered, and Mic Control supports remote effect switching with a compatible TC Helicon microphone. A Mini-USB connection provides computer access for supported firmware and product updates, while the die-cast metal chassis is designed for regular stage use.
