BOSS has announced the latest member of its famous compact pedal lineup. Rotary speaker cabinets are a vital part of the classic combo organ voice, and guitarists and other musicians have also used them to infuse iconic tracks with their distinctive depth and rich modulation.
Powered by the latest BOSS advancements, the RT-2 Rotary Ensemble distills this expressive spatial effect into a pedalboard-friendly footprint with three sound modes, deep tonal shaping, multiple audio output configurations, and advanced real-time sound control.
The most revered rotary speaker designs feature a spinning high-frequency horn (treble rotor) and a woofer that feeds into a rotating drum (bass rotor). Changing rotor speeds between fast and slow creates a steady stream of tonal shifts that players have long used for interesting sonic movement. The RT-2 authentically replicates these complex audio behaviors, coupled with two-way speed control, a Rise/Fall Time switch for adjusting the transition time between speeds, and a colorful indicator that shows the current rotation of the virtual rotors.
The versatile RT-2 has a three-position Mode switch for selecting a classic rotary speaker sound or two modern variations developed with custom BOSS tuning. There’s also a Drive knob to add pleasing distortion inspired by the tube amplification circuits in vintage rotary speaker cabinets. Via a rear-panel switch, this dual-function control can be assigned to adjust the volume balance between the treble and bass rotors for different tonal characteristics.
Real-time speed control is essential to the rotary experience, and the RT-2 includes many options to achieve it. The pedal switch offers four operation types with clever ways to bypass the effect and change speeds while performing. Connecting external footswitches provides independent speed control and access to a “brake” setting that stops the virtual rotors at their current positions for unique tones. Alternately, an expression pedal unlocks continuous control of level, drive, balance, and speed, complete with assignable settings for each parameter.
The BOSS RT-2 Rotary Ensemble will be available in July 2025, priced $239.99 USD.
