Boss RT-2 Rotary Ensemble

Step into the swirling, speaker-spinning world of rotary effects with the BOSS RT-2 Rotary Ensemble — a premium stereo rotary speaker pedal built to capture the soulful, immersive sound of classic rotating speaker cabinets. With its advanced DSP and intuitive controls, the RT-2 delivers a lush, dimensional sound that’s equally at home recreating vintage gospel tones, prog-rock psychedelia, or ambient textures that drift and spin through space.

Using proprietary Roland/BOSS Adaptive Focus conversion, the RT-2 captures the nuances of your tone with outstanding clarity and a dramatically improved signal-to-noise ratio. Whether you’re aiming for the smoky, organ-style tones of Don Leslie’s legendary invention or chasing the liquid modulation heard on David Gilmour’s iconic leads, the RT-2 is a powerful tool that puts expressive rotary magic at your feet.

It features independent controls for SLOW and FAST speeds, onboard DRIVE for tube-like saturation, and stereo I/O for wide, engulfing modulation. The VIRTUAL ROTOR light gives visual feedback of your rotation speed, and flexible input/output options mean this pedal fits effortlessly into mono or stereo rigs. Pair it with an expression pedal or footswitch for dynamic speed control on stage — or hook it into your studio setup for massive swirling textures on guitar, synths, or even vocals.

If you’re inspired by the rotating speaker textures used by guitar legends like Jimi Hendrix, David Gilmour, or Jeff Beck, the RT-2 Rotary Ensemble brings those lush, moving tones into the modern age with precision and flexibility. It’s not just an effect — it’s an experience.
