The Roto Choir recreates both the rotating lower speaker and the treble rotor horn –the only way to attain that complex, multi-dimensional tone. In fact, the Roto Choir utilizes a specifically formulated SansAmp technology to deliver the entire signal chain –from the original tube power amp to the speaker and high-frequency rotor horn, to the microphone used to capture it. This is HD, 3D emulation. The simple controls hide a wealth of options. Drive adds just the right amount of compression, harmonics and grit. Low and High sculpt the tube amp emulation with powerful EQ curves. The Fast/Slow footswitch allows users to ramp up, slow down or even stop the rotating speaker. There’s also a dedicated control to custom set the Top Speed of your rotor. Want to vary the intensity of the effect? Simply adjust the Position control to move the Roto Choir’s virtual mic closer or further from the horns. Other features include a biamped/single-speaker mode switch, stereo output and a Speaker Sim switch for direct recording.
