The Boss RT-2 Rotary Ensemble is a compact pedal delivering authentic rotary speaker emulation with three distinct effect voicings. Features concentric dual knobs controlling Slow and Fast rotation speeds and Level and Drive adjustment, with three crown switches selecting bass/treble horn balance, ramp time between speeds, and mode voicing. Mode 1 models a vintage rotary speaker with preamp tones, Mode 2 adds natural spatial ambience, and Mode 3 delivers enhanced modulation with expanded drive range. Stereo inputs and outputs plus TRS external speed jack. Reviewed by Guitar World, Premier Guitar, and Sound on Sound.
The Tech 21 RotoChoir is a rotary speaker simulator from Tech 21 in New York, delivering a Leslie cabinet-inspired swirling Doppler effect with adjustable fast and slow rotor speeds plus cabinet simulation, all without needing a real rotating-speaker cabinet. It suits organ-influenced, classic-rock, and vintage players wanting Leslie-style swirl in pedal form rather than hauling an actual rotary cabinet.
