RotoChoir

The Tech 21 Roto Choir is a rotary speaker effects pedal designed to emulate the sound and response of both a rotating lower speaker and a treble rotor horn. Using proprietary SansAmp technology, this modulation stompbox replicates the entire rotary speaker signal chain, including tube power amp behavior and microphone capture. The pedal provides control over drive, EQ, top speed, rotor acceleration, and microphone position, offering precise emulation adjustments. The Fast/Slow footswitch allows real-time switching between rotor speeds, and additional features include a biamped/single-speaker mode, true stereo output, and an onboard speaker simulator for direct recording applications. **Key Features:** - Rotary speaker effects pedal with SansAmp signal chain emulation - Drive, Low, and High EQ controls for detailed tone shaping - Fast/Slow footswitch and adjustable top rotor speed - Position control for virtual microphone placement - Biamped/single-speaker mode and stereo output - Speaker simulator switch for direct recording
