BOSS RT-2 Rotary Ensemble Effects Pedal ( 121208052

( ALL OTHER COMPONENTS SHOWN IN IMAGES ARE SOLD SEPARATELY )

The BOSS RT-2 Rotary Ensemble effects pedal brings classic rotary speaker sound and advanced controls to your pedalboard in a compact, rugged format. Powered by the latest BOSS modeling, this unit recreates the moving air and complex spatial effects of vintage rotary cabinets with surprising detail. Players can choose from three unique rotary modes, each offering a different take on the swirling, modulated textures once only possible with heavy organ speakers. The pedal's drive section mimics tube saturation, while the dual-axis knobs let you tweak speed, drive, and horn/bass balance on the fly. Designed for guitarists who want immersive modulation and real-time control, the stompbox includes stereo I/O and deep footswitch options for smooth transitions between speeds or effect bypass. This pedal fits neatly into modern setups, delivering lush movement and depth for players who want classic sounds without hauling heavy gear.

Three Rotary Modes Shape Distinct Modulation Effects

The RT-2 features a three-way mode switch that selects between authentic vintage rotary, a modern wide-ambience setting, and an enhanced definition mode. Mode I captures the sound of classic rotary cabinets, including the unique preamp color. Mode II expands the tonal range for greater space, especially when paired with distortion pedals. Mode III increases modulation and presence, creating a bold, swirling effect for solos or arpeggios. Each mode changes the unit's internal algorithms, so players can quickly dial in the exact movement and vibe they want for different setups.

Drive and Balance Controls Add Vintage Saturation or Custom Tone

This stompbox includes a drive knob based on tube circuits found in original rotary speakers. Players can add gentle warmth or crank it for gritty overdrive. A rear-panel switch reassigns the drive knob to balance the level between the horn and bass rotors, acting as a tone filter. These settings auto-save in memory, so users keep their favorite sounds after powering down. The pedal's dual-use drive control helps create unique tones that cut through a band mix or sit back for subtle movement.

Real-Time Control and External Switching Increase Flexibility

The BOSS pedal offers several ways to manage rotor speed and bypass. The main footswitch toggles between fast and slow rotor speeds and can bypass the effect with a tap. Connect up to two external switches for independent speed switching or braking, which stops the rotors for a unique sound. The expression pedal input supports real-time changes to level, drive, or speed, giving users responsive control during live sets. A visual rotor display shows current speeds for both horn and bass, making adjustments easy under stage lights.

Durable Construction Built for Heavy Use

Measuring just 2-7/8" x 5-1/8" x 2-3/8" and weighing only 1 lb., the RT-2 uses a tough enclosure and high-quality jacks to survive gigging and frequent travel. Buffered bypass keeps the signal strong in any pedal chain. The internal electronics use 24-bit AD and 32-bit DA conversion with Roland's Adaptive Focus method, keeping noise low and tone clear. Players can power the unit with a 9V battery or PSA-series adaptor for reliable operation on any stage.

Player Experience With the BOSS RT-2 Rotary Ensemble

Serious guitarists or keyboardists who want rotary speaker sounds without moving a heavy cabinet will appreciate this stompbox. The BOSS RT-2 gives live players hands-on, real-time control and deep tonal tweaks for expressive, spacious effects. Every detail—from the drive circuit to the rotor speed display—works together to deliver a unique, immersive modulation that stands out in any live mix or studio session.
