Overview

Bring your own vocal accompaniment to any venue.

The TC Helicon CRITICAL MASS stompbox brings studio-quality vocal effects right to your feet. The CRITICAL MASS pedal lets you add lush reverbs, harmonies, doubled vocals and tone sculpting to make your voice sound bigger and more professional. With the stomp of your foot, you can engage your audience and set the perfect mood by having enthusiastic group vocals on demand.

Shape Your Tone With Reverb and Doubling Effects

The CRITICAL MASS pedal has carefully crafted presets to enhance and shape your vocal tone. Add dimension to your voice with the natural-sounding Hall and Room reverbs. Thicken up your vocals with the doubling effects, which add a pitch-shifted second vocal track blended underneath your original. You can even add a touch of grit and edge with the onboard distortion effects. The simple stompbox interface makes it easy to switch between effects in real time.

Energize Your Audience With Vocal Harmonies

Bring your performances to the next level by engaging your audience to sing along. The CRITICAL MASS pedal offers one-touch access to vocal harmonies in different styles. Choose from four presets of lush "melodic" harmonies or four presets of energetic "gang"-style harmonies. Just plug in your microphone and you'll have professional backing vocals at your command. Create an enthusiastic singalong or intimate worship vibe with ease.

Enhance Any Musical Style

Whether you're playing rock anthems in an arena or leading worship in your local church, the CRITICAL MASS pedal can enhance your vocals. The harmonies and effects work with any musical style, from pop and rock to country, hip-hop, R&B and more. Create lush backing vocals in real time, without the need for backing singers. With the CRITICAL MASS pedal, you'll always have the perfect effects and harmonies to support your voice.
