Boss RT-2 Rotary Ensemble Pedal

Rotary speaker cabinets sound amazing, but their size and weight make them impractical for anyone but the most dedicated vintage enthusiasts. Powered by the latest BOSS advancements, the RT-2 Rotary Ensemble distills this expressive spatial effect into a footprint that’s easy to integrate into every setup. This powerhouse pedal authentically recreates the complex sonic magic of its inspiration, supported by three sound modes, deep tonal shaping, and advanced operation with the onboard pedal switch and external control.

Features

• Authentic rotary speaker sounds and behaviors condensed into a space-saving BOSS compact pedal
• Three versatile modes include a vintage rotary sound and two modified tones with enhanced spatial effects
• Virtual rotor display with lights that indicate treble and bass rotor speeds
• Fast/slow rotor speed control
• Drive knob to add vintage tube saturation
• Rise/Fall Time switch adjusts the transition time between rotor speeds
• Drive/Balance switch assigns the Drive knob to control the saturation amount or the volume balance between the treble and bass rotors
• Four selectable pedal switch modes for bypassing the effect and controlling the rotor speed in various ways while performing
• Support for advanced control with external footswitches or an expression pedal (speed, brake, and other functions)
• Mono/stereo input and output
