SUHR ALEXAMULTI-WAVE DUAL CHANNEL ANALOG CHORUS/VIBRATO

Alexa is a Multi-Wave Dual Channel Analog Chorus/Vibrato that offers a fresh approach in delivering a wealth of warm modulation and spatial effects for your guitar, bass or keyboard.

SIX WAVE-FORMS
TO EXPLORE

Experience chorus in a whole new way. Alexa’s six onboard wave-forms offer a comprehensive palate of vintage and modern chorus sounds.

TWO CHANNELS ARE BETTER THAN ONE

With Alexa’s two independent channels, you can easily preset two distinct chorus/vibrato sounds. For example, Channel A can be a traditional warm and smooth chorus, while Channel B is set to a fast vintage rotary.

Switching between two different sounds has never been easier.

TWEAKERS WELCOME

Alexa features a comprehensive palette of controls that are musical and easy to use. Each channel is equipped with dedicated wave-form, speed, delay, and depth controls to give you complete control over fine-tuning your sound.

100% PURE ANALOG SIGNAL PATH

A combination of vintage technology and modern engineering is the foundation which Alexa was built upon. The heart of Alexa’s signal path employs a 3207 BBD (bucket brigade device) to deliver all of the warm analog tones that vintage choruses are revered for. Innovative engineering ensures the purest analog tone, with ultra-quiet performance.

EXPRESS YOURSELF

You can vary the speed control in real-time by simply connecting an external expression pedal or tap tempo footswitch.

WAVEFORMS

Alexa contains six musical waveforms to choose from when dialing in a chorus/vibrato setting.

Triangle: Smooth, lush chorus.

Sine: Throbbing, even pitch bends.

Rotary: Swirling rotary speaker emulation.

Photocell: Asymmetrical shape and sound.

Ramp Down: Rhythmic downward modulation.

Ramp Up: Rhythmic upward modulation.

SPEED CONTROL

Adjusts the speed at which the modulation occurs. Turning the knob clockwise sets the speed to up to 10Hz. Turning the knob counter clockwise sets the speed down to 1/2Hz.

DELAY CONTROL

Adjusts the delay point that chorus modulates around. This ranges from 10ms to 40ms.

 Tip: Increasing the Delay typically gives a “wider” sound. If the chorus’s pitch wobbles too dramatically, counteract by decreasing the Depth control to keep a smoother chorus sound.

DEPTH CONTROL

The depth knob reduces (counter clockwise) or boosts (clockwise) the amount of modulation.

CHORUS/VIBRATO SWITCH

This switch is only active on channel A. This allows you to turn Channel A into a vibrato effect (pitch bending).

A/B SWITCH

Alexa has two channels (green and red) with independent settings that are selected by the switch labeled A/B. The channels can be set for the same sound on each channel with slight modifications, or they can be radically different.

The left side is Channel 1 and is indicated by a
GREEN LED.

The right side is Channel 2 and is indicated a
RED LED.
