There`s nothing like having a large

and enthusiastic audience singing

along with you. CRITICAL MASS puts

that magic right at your feet in an easy

to use stomp box.

Whether you`re pounding out arena rock-style

anthems or leading worship at your church,

having group vocals on demand allows you to

set the mood and engage your entire audience.

Choose from melodic or gang style vocals

that suit any style of music with no key or scale input required.

Reverb simulates a physical space, allowing your voice to fit into the music perfectly. Whether it`s the

ambience of a small room, or the massive reverberation of a concert hall, CRITICAL MASS` 3 vocally

tuned reverbs always brings out the best in your voice.

CRITICAL MASS` Adaptive Tone (equalization) with compression, de-esser and gate automatically

control the timbre and shape of your sound, ensuring every note is pristinely clear and intelligible.

When the crowd hears exactly what you`re singing, they can join in – and there`s nothing better

than that!

You`re a singer first and foremost, so getting knee-deep in technology probably isn`t what your

gig calls for. That`s why CRITICAL MASS automatically sets your mic gain to the optimal level,

allowing you to concentrate on giving your best performance – night after night.

CRITICAL MASS gives you the option of either plug-in power via the optional POWERPLUG 9 V

adapter – or battery operation for those occasions when you`re just doing a short set, or house

power isn`t readily available.

Whether you`re playing at the local tavern or a huge festival, your vocals always deserve special

attention. CRITICAL MASS gives you the tools to always sound your best with melodic and gang vocals,

state-of-the-art reverb and adaptive tone – all in an ultra-simple stomp box designed to

elevate your performance to the next level.
