The TC-Helicon Duplicator vocal effects pedal lets you tap into three studio-quality vocal effects in a stompbox. Your mic plugs directly into the high-quality, low-noise mic preamp. Then you can dial in your ideal combination of doubling, reverb, and pitch correction effects. The Duplicator is equipped with TC's acclaimed Adaptive Tone circuit, which simultaneously tunes EQ, compression, de-essing and gating specifically for your voice. I have used it in studio at times and like the the effects. Get it in time for Christmas!
