TC Helicon Critical Mass Vocal Harmony Effects Pedal

Imagine commanding an entire arena of voices with just one stomp box at your feet. The CRITICAL MASS brings that electrifying crowd vocal experience directly to your performance, offering both “melodic” and “gang” style vocals that work seamlessly across any musical genre without requiring key or scale input. This innovative pedal puts the power of audience engagement right where you need it most – from arena rock anthems to worship settings.

Three vocally-tuned reverb settings simulate everything from intimate room ambience to massive concert hall reverberation, ensuring your voice sits perfectly within the mix. The built-in Adaptive Tone technology combines equalisation, compression, de-esser and gate functions to automatically shape your sound, guaranteeing crystal-clear vocal intelligibility that encourages audience participation.

Designed with performers in mind, CRITICAL MASS automatically optimises your microphone gain levels, letting you focus entirely on your performance rather than technical adjustments. Power options include the optional POWERPLUG 9V adapter for extended use, or battery operation for shorter sets and venues where mains power isn’t accessible, making it the perfect companion for any vocal performance scenario.
