The TC-Helicon Duplicator is a stompbox pedal that allows you to use any combo of vocal and octave doubling, reverb, and pitch correction effects on your voice. And because the pedal has a built-in preamp, you can plug your mic directly into it.

Many voices, one song
The TC-Helicon Duplicator pedal adds vocal effects that improve your live sound, available in an easy-to-use stompbox. Just plug in your microphone in the pedal, which has a built-in preamp, and set your preferred combo of doubling (including octave doubling), reverb, and pitch correction effects. Along with these killer options, TC’s Adaptive Tone circuit tunes EQ, compresses the audio, and de-esses everything.

Because it’s a stompbox, you can turn the doubling on and off with the footswitch, making it super easy to shift between different sections of the song.

Double or nothing
Double tracking has been a staple in studio recording for decades. It adds punch and interest at just the right moment. Duplicator brings that studio sound to your live performances, giving you tight, loose and octave options that perfectly suit your song.

Choose your space
Reverb simulates a physical space, allowing your voice to fit into the music perfectly. Whether it’s something small like a room or large like a concert hall, Duplicator’s vocally tuned reverb compliments your voice.

Let us give you a nudge
We’re all human and nobody hits every note perfectly. Nobody. With transparent auto-chromatic pitch correction, we nudge your pitch to the nearest semitone. It won’t turn a potato into a spaceship, but it can give you a little support when you need it most.

A mixing board at your feet
Adaptive EQ (equalization), compression, de-ess and gate automatically control the timbre and shape of your vocal, ensuring that every note you sing is clear and intelligible to your audience. When the crowd can hear what you’re singing, they can sing along. Nothing is better than that!

Auto mic gain
Mucking about with mic gain can be a real hassle, especially if you’re in a hurry or at a new and unfamiliar venue. Duplicator automatically sets your mic gain, so you never have to worry whether things are set correctly.

Who needs sockets?
Sometimes it’s just not feasible to find a power outlet when you’re performing. That doesn’t mean you should be without your Duplicator! It can be powered by 4 AA batteries (not included) in addition to the optional 9V adapter.
