Boss RT-2 Rotary Ensemble

The RT-2 Rotary Ensemble offers a wide range of rotary speaker sounds in one small pedal – from authentic vintage recreations to modern variations with expanded sonic possibilities.

Designed for guitar use, the RT-2 delivers rich, immersive sounds with pulsing, swirling, and chorus-like textures that add even more depth to your playing. In addition to the classic rotary speaker sound, the pedal features three individual rotation modes, adjustable preamp drive, and control of the balance between the horn and bass rotors for dynamic, three-dimensional modulation effects.

Classic rotary speaker and preamp sounds,
including optimized variations for a denser spatial sound and an extended drive range.

Advanced sound processing with new, dual-axis knobs for controlling rotor speed, preamp drive, speed parameters (slow/fast), and horn/bass rotor balance.

The pedal switch allows for seamless transitions between slow and fast rotor movement, accurately reproducing tonal nuances during the transition.

Virtual rotor display visually displays the movement of the horn and bass rotors for instant feedback.

Multifunctional pedal switch for controlling the speed (slow/fast) and effect (on/off).

Additional Speed ​​input enables separate slow/fast control via an external footswitch.
