When Strymon decided to create a studio-class pedal that faithfully recreates the classic, unmistakable sound of the most sought-after rotating speaker system, they prepared to study every nuance and finest detail. The Strymon sound design labs were filled with those signature, swirling, three-dimensional sounds as they painstakingly analyzed and recreated the physics and mechanics behind these systems.
- Handcrafted rotary algorithms faithfully deliver the signature, three-dimensional rotating speaker experience
- Extensive control over rotating speaker mechanics and configuration
- Four rotary adjustment and tone shaping knobs: Fast Rotor Speed, Preamp Drive, Mic Distance, Horn Level
- Four 'hidden' knobs for extensive tone tweaking: Slow Rotor Speed, Cab Direction, Acceleration Time, ±6dB Boost/Cut
- Instantly alternate between a fast and slow rotor speed with the Slow/Fast stomp switch
- Selectable cab filter allows for an optimal experience in front of guitar amplifiers and full range systems
- Selectable Bi-Amp mode splits bass rotor and treble horn signals to separate outputs
- Expression pedal input with selectable control over any knob parameter
- Connect an optional footswitch to save a favorite preset or use as an external speed switch
- Premium analog front end and output section
- Ultra low noise, high performance 24-bit 96kHz A/D and D/A converters
- True bypass via electromechanical relay switching
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 among 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, including 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 or costly motor maintenance.
Slow/Fast switch
Alternate between a slow and fast rotor speed. Ramp up and slow down with the press of a switch.
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
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
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.
