The TC Helicon VoiceTone D1 vocal effect pedal is a doubler and detuner that brings a thick, studio-quality sound to your live performances. Switch between eight detuning and doubling effects that range from standard octave up or down to tripped-out chorus sounds, then blend the dry signal back in for an even fatter tone. Chain it up with your other VoiceTone pedals to create the signal path of your dreams, and remotely engage or bypass the D1 with TC Helicon's MP-75 handheld microphone, giving you control of the effect when you're away from the pedal.
