Provide your audience with the sound of a large group of singers with Critical Mass from TC-Helicon, a vocal FX processor pedal that offers powerful melodic and gang-like group vocal sounds across eight selections. With intuitive 3-knob control and Adaptive Tone, you can just start singing, no need to set a key or scale.
Like most TC-Helicon vocal processors, Critical Mass also includes intelligent mic input gain, so you never have to set levels. Precisely control the level of lead versus crowd sound and shift through several styles of studio-quality reverb. When you want to bypass your FX to address your crowd, but keep the pristine tone, hit the Tone button and stomp the footswitch. Constructed from a durable die-cast metal case, Critical Mass is road worthy and ready to survive years of abuse.
