The BOSS RT-2 Rotary Ensemble condenses the complex modulation of vintage rotary speaker cabinets into a compact, stereo pedal format. Using advanced DSP modeling, it accurately replicates the interplay between a spinning high-frequency horn (treble rotor) and rotating bass drum—key components of classic rotary speaker systems.
The pedal offers three modes:
- Mode I: a Faithful emulation of vintage rotary cabinets
- Mode II: an Enhanced spatial effect for use with drive pedals
- Mode III: a High-definition modulation for cutting through mixes
A virtual rotor display visually tracks speed changes, while the Drive knob adds tube-like saturation. Users can adjust rotor balance and speed transition times (Rise/Fall) for customized response.
Four footswitch modes allow flexible speed toggling, with support for external expression pedals or dual footswitches (for speed/brake functions). Stereo I/O preserves spatial imaging, with selectable wet/dry routing.
For players seeking rotary speaker tones without the bulk, the RT-2 delivers authentic behavior in a stage-ready package.
