TC Helicon Critical Mass Product Overview by GAK

The TC Helicon Critical Mass promises to inject atmosphere into your live performance with an easy to use vocal stompbox.

The Critical Mass pedal allows you to engage with your audience whatever environment you're playing in, whether it be in a small local venue, a festival stage or even in a church as you can choose from "melodic" or "gang" style vocals. The three studio-grade reverb styles are highly adaptable to the ambience of any room to bring out the best in your performance. 

Compression, de-esser and gate control the shape of your sound, guaranteeing precision and clarity with every note, giving you the peace of mind that your audience can hear exactly what you're singing and join in!

With simplistic controls, the Critical Mass automatically sets your mic gain to the optimal level, letting you concentrate giving nothing less than your best performance every night.
