Boss RT-20 Rotary Ensemble Specification

The Boss RT-20 Rotary Ensemble is a sophisticated effects pedal designed to emulate the classic rotary speaker sound. It features advanced COSM (Composite Object Sound Modeling) technology to deliver authentic rotary speaker tones, replicating the complex interaction between the horn and drum components of traditional rotary cabinets. The pedal provides a wide range of adjustable parameters including speed, ramp time, and balance control, allowing users to fine-tune the modulation effect to suit their musical needs.

The RT-20 is equipped with four preset modes that simulate different rotary speaker types, offering versatility for various musical styles and settings. Its speed control knob allows for real-time adjustment of the rotation speed, while an acceleration knob lets users set the rate at which the speed changes, mimicking the natural acceleration and deceleration of a mechanical rotary speaker. The pedal also includes a unique blend control, which enables users to mix the wet and dry signals for optimal balance.

A key feature of the RT-20 is its stereo output, which enhances the spatial dynamics of the rotary effect, providing a rich and immersive sound experience. The pedal is housed in a rugged, roadworthy chassis, ensuring durability for both studio and live performance applications. Additionally, its intuitive interface and clear LED indicators make it user-friendly, even for those new to rotary effects. With its combination of authentic sound modeling and flexible controls, the Boss RT-20 Rotary Ensemble is ideal for guitarists and keyboardists seeking to incorporate the iconic rotary speaker sound into their music.
