Strymon Lex Rotary Effect Pedal

Born to Revolve.

When we decided to create a studio-class pedal that faithfully recreates the classic, unmistakable sound of the most sought-after rotating speaker system, we prepared to study every nuance and finest detail. The Strymon sound design labs have been filled with those signature, swirling, three-dimensional sounds, as we painstakingly analyzed and recreated the physics and mechanics behind these systems.

Lex provides you with a complete, accurately reproduced rotary system: the low-frequency bass rotor, the rotating treble horn, the tube-driven amplifier, finely tuned microphone placement, and all the complex sonic interactions between these elements. Utilizing a ridiculously powerful SHARC DSP, every drop of processing power is harnessed to authentically represent these details.

You get eight parameters to tweak, allowing extensive control over the tonality and mechanics of the rotating speaker system. You can manipulate each element, from rotor speed, horn level, acceleration time, microphone distance, tube drive and saturation, and volume level. Go from a maelstrom of dramatic, up-close, sweeping and swirling sounds, all the way to mellow, tranquil and calming undulations. All of this without a giant cabinet, microphone setup, and costly motor maintenance.

Four rotary adjustment and tone shaping knobs: Fast Rotor Speed, Preamp Drive, Mic Distance, Horn Level.

Four “hidden” knobs for extensive tweaking: Slow Rotor Speed, Cab Direction, Acceleration Time, +/- 6dB Boost/Cut.Your 4-knob Lex Rotary is actually a 8-knob rotating speaker machine!

Alternate between a fast and slow rotor speed. Ramp up and slow down with the press of a switch

Press and hold the Fast/Slow switch to put the brakes on. The Lex rotary will wind down and stop. When at rest, the horn and drum “brake angle” is optimally positioned for consistent results. Release the Fast/Slow switch and the rotary will begin to spin.

Lex provides you with a selectable Bi-Amp mode to send bass rotor signal out to the Left output, and the treble horn to the Right output. Stack two cabinets and add another dimension to your sound.

What's Happening Inside?

Lex rotary delivers a faithful reproduction of the entire rotating speaker system. It’s all here—the low-frequency bass rotor, the rotating treble horn, the tube-driven amplifier, finely tuned microphone placement, and all the complex sonic interactions between these elements.
