The Strymon Lex Rotary Speaker Effect Guitar Effects Pedal recreates the sublime tonal offerings generated by the coveted 'rotary speaker system'. Everything has been accounted for: a low-frequency bass rotor, a rotating treble horn, a tube-driven amplifier, adjustable microphone placement, and a complete representation of the sonic complexities produced by these mechanical elements. Simply put, you have an entire rotary speaker system in a compact stompbox!

The Lex nails a host of rotary speaker tone(sic), but it also delivers a lot of the response and feel of playing one in impressive fashion.

- Premier Guitar

The Lex's ability to perform such an illustrious feat, comes from Strymon's adoption of the exceptionally powerful SHARC DSP circuitry, which carries out vast calculations with ease to ensure smooth, seamless control over the entire system. Everything is beautifully contained with a strong and lightweight mahogany-coloured anodized aluminium chassis, guaranteeing its resilence and strength to take anything that comes its way.

Intuitive Control, Delightful Results

The front panel is home to two footswitches (Slow/Fast and Bypass), and four control knobs that each have secondary functions - which are accessible by holding down both footswitches simultaneously.

As the label suggests, the Fast Rotor Speed knob controls the speed of the rotors in FAST mode. It's secondary function, Slow Speed, controls the speed of the rotors in SLOW mode. Whether you want to create a subtle effect, or a revved up whirlwind, all you need to do is attenuate this knob in your mode of choice.

The Mic Distance control allows you to vary the distance of the stereo mic arrangement from the horn rotor and the single mic on the woofer rotor. Creating a choppy, revved up effect is easily achieved by setting the distance as short as possible, whilst a lilting, softly yielded response is produced at the furthest distance. The secondary function of this pot controls Cab Direction, allowing you to develop to tonal intensity of your mic placement with greater control.

The Preamp Drive knob enables you to ramp up the gain in the tube preamp to create a gritty, overdriven snarl. The secondary function controls the +/-6dB boost or cut when the pedal is engaged, allowing you to create as subtle or dramatic an effect as you wish.

The Horn Level knob controls the output level of the high frequency horn rotor. The secondary function allows you to attenuate the Acceleration of each horn from Fast to Slow or Slow to Fast. Depending on your preference, you can achieve a stacked to wavey effect, or go from a soft to shimmering sparkle.

Expression/Favourite Inputs

Along the rear panel you will find the high impedance mono input, which allows you to connect guitars, and stage pianos/keyboards. Connect a standard TRS expression pedal for continuous control over any selectable knob parameter. To select the knob controlled by the expression pedal, hold the SLOW/FAST footswitch during power up. The first knob turned is then then assigned to the expression pedal. The maximum position the knob is turned up to becomes the expression pedal “toe down” maximum value. Moving the pedal to the “heel down” position activates the rotor brake when the expression pedal is assigned to control speed.

If you'd prefer to use a Strymon Favourite pedal instead of an Expression pedal, simply hold both footswitches down when you power up the pedal and turn the Fast Rotor Speed knob fully clockwise (i.e. fully anti-clockwise for Expression Pedal assignment). This allows you to save and recall your favourite settings at any time using your Favourite Pedal.

Additional Controls

While holding down both footswitches at power up, the Mic Distance control can be adjusted to tailor the cabinet filter for use in front of a guitar amp or a full range speaker, e.g. studio monitors - which is better suited to direct recording into your DAW of choice.

Again, holding down both footswitches at power up, and adjusting the Preamp Drive control allows you to activate/de-activate Bi-Amp mode. This means that the left output is set to the horn signal, whilst the right output is the woofer signal. This allows you to send each signal to different channels, speakers, whatever you wish, to expand the potential of this little beauty even further.
