TC Helicon VoiceTone H1 — Guitar-Guided Vocal Harmony Stompbox

The TC Helicon VoiceTone H1 brings real-time vocal harmony to solo singers and acoustic performers in a single stompbox. Plug in a microphone, connect a guitar (or set the key manually), and the pedal generates one or two natural-sounding backing voices that follow the lead vocal. The unit reads chord information from the connected guitar and shifts the harmony intervals to stay in tune as songs progress.

What Sets the VoiceTone H1 Apart

Inside the rugged die-cast metal chassis sits the same quality processing found in TC Helicon's flagship VoiceLive rack units, paired with a clean, low-noise mic preamp. The Mic Control function turns the effect on and off remotely when used with a TC Helicon MP-75 or Sennheiser e835 FX microphone. A ground-lift switch eliminates hum from problematic AC power setups.

Connections, Audio Performance & Power

Balanced XLR microphone input and output handle the main signal path, while a 6.3 mm instrument input reads the guitar for chord detection and a matching output passes the guitar signal through. A Mini-USB port handles firmware updates via the VoiceSupport application, with no MIDI or audio streaming over USB.

• Microphone Input: XLR with 24V phantom power — supports dynamic and stage condenser mics
• Instrument I/O: 6.3 mm TS input and thru-output — feeds harmony engine, passes guitar onward
• USB: Mini-USB to host (firmware updates only) — no MIDI, no audio streaming
• Power: 12 VDC at 400 mA via included adapter — 5.6 W, no battery operation
• Audio Performance: 20 Hz–20 kHz, >104 dB dynamic range, −126 dBu EIN
• Compact die-cast chassis measuring 137 × 89 × 58 mm, weighing 0.42 kg — fits beside a tuner on any pedalboard

Solo Singers, Acoustic Duos & Worship Leaders

This stompbox is the right choice for solo vocalists who need convincing two-voice harmony without recruiting a backing singer, and for acoustic guitarists who want their chord progression to drive the harmony automatically. Worship leaders benefit from hands-free Mic Control with a compatible TC Helicon or Sennheiser microphone. Multi-pedal vocal chains daisy-chain easily with other VoiceTone Singles like the R1 reverb or C1 correction pedal.
