A quintessential tool for vocalists seeking to enhance their live performances, the TC Helicon Critical Mass Pedal delivers an innovative and high-quality solution for achieving the elusive gang vocal effect with ease and precision. This durable and user-friendly pedal is expertly designed to simulate the sound of a crowd singing along, creating a powerful chorus effect that can elevate any stage performance.
Crafted by the reputable brand TC Helicon, known for its exceptional audio equipment, the Critical Mass Pedal stands out with its versatility and positive user feedback. Vocalists can effortlessly generate the energy of a fully engaged audience without depending on the crowd's participation. This is achieved through the intuitive Style knob, which allows the selection of four distinct audience-emulating vocal modes: unison, octave up, octave down, and a hybrid of octave up and down. These settings provide the flexibility to match the desired vocal arrangement with precision.
Beyond gang vocals, the pedal offers four melodic settings that maintain pitch in harmony with the vocalist, without the need for key or scale input. This feature distinguishes the Critical Mass Pedal from other TC Helicon pedals that may require an instrument connection for harmonic guidance. Instead, this pedal focuses on delivering pure unison and octave vocals, free from external harmonic constraints.
The Critical Mass Pedal is also equipped with three studio-grade reverb effects, adding depth and ambiance to vocal performances. The inclusion of TC Helicon's adaptive tone technology is a testament to the pedal's sophistication, automatically fine-tuning EQ, compression, de-essing, and gating to ensure a polished and consistent vocal output.
For added convenience, the pedal can be powered by four AA batteries or an optional power supply, and it offers phantom power support for microphones that require it. The TC Helicon Critical Mass Pedal is a versatile and innovative choice for vocalists looking to bring studio-quality gang vocals and melodic harmonies to the live stage.
