Boss RT-2 Rotary Ensemble — Authentic Leslie Motion in a Compact Stompbox

The Boss RT-2 Rotary Ensemble distills the swirling motion of a vintage Leslie rotating speaker into a pedalboard-friendly stompbox. Powered by BOSS's latest modeling technology, this compact pedal recreates the dual-rotor behavior — a spinning high-frequency horn and a rotating bass drum — that has defined organ and guitar tones for decades. It is a complete rotary speaker simulator with three modes covering authentic vintage character and modern variations.

Three Rotary Modes and Visual Rotor Feedback

A three-position Mode switch delivers a faithful vintage Leslie recreation (Mode I), a wider-range variation tuned for overdrive and distortion pairings (Mode II), and an intense modulation voicing with built-in drive for solos and arpeggios (Mode III). A virtual rotor display with colored LEDs visually mirrors the rotation of the treble horn and bass drum in real time, giving players intuitive feedback during performance.

High-Resolution Audio Engine

A high-resolution processing engine captures the harmonic complexity of a real rotary cabinet at studio-grade sample rates and bit depths.

• The sample rate of 48 kHz captures the full bandwidth of the rotating speaker simulation.
• AD Conversion: 24-bit + AF method — Roland/BOSS Adaptive Focus method improves signal-to-noise ratio for cleaner modulation
• DA Conversion: 32-bit — high-headroom output preserves dynamic detail through the stereo field

Full Control Surface and Stereo Routing

Stacked concentric knobs handle fast/slow speed and level/drive, with dedicated switches for mode selection and ramp time.

• Controls: Level, Drive, Mode Selector, Fast, Slow, RISE/FALL TIME switch, DRIVE KNOB switch — all rotary parameters accessible from a single panel
• Inputs: 2 × 6.3 mm TS (mono/stereo) plus CTL/EXP TRS — supports stereo sources and expression pedal or footswitch control
• Outputs: 2 × 6.3 mm TS (mono/stereo) — runs standard stereo or split wet/dry output modes

Pedalboard-Ready Power and Compact Footprint

The RT-2 keeps the standard BOSS compact footprint and runs on either battery or a PSA-series adaptor.

• Bypass: Buffered — preserves signal quality through long cable runs and large pedalboards
• Power: 9 V battery (alkaline) or PSA-series adaptor, 115 mA current draw — flexible power for stage and studio setups
• Dimensions of 73 × 129 × 59 mm and a weight of 450 g allow it to fit any standard pedalboard layout.
