Strymon's description of the Strymon Lex rotary rotating speaker effects 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.

 

The complete rotary system.

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.

Extensive control.

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.




Features

Slow/Fast Switch

Change between Rotor Speeds

Alternate between a slow and fast rotor speed.

Ramp up and slow down with the press of a switch.


 

Rotary Brake

Press and Hold for Rotary Brake

Press and hold the Slow/Fast 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 Slow/Fast switch and the rotary will begin to spin.


 

Bi-Amping

Rotating Speaker Bi-Amping

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.

 

Expression Pedal

Expression Pedal

You get an expression pedal input with assignable control over any front-panel knob parameter. When set to Fast Rotor Speed, you can sweep and ramp all the way from the “braked” position up to a selectable speed.





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.
