The AUTO Series fuses classic pedal design with groundbreaking parameter automation. It’s more than just an evolution in audio processing—it's a complete reimagining of what a pedal can be.

With every AUTO Series pedal, your performance becomes an integral part of the sound effect!

Your touch, playing dynamics, and note choices shape the tones and textures, responding to your performance and evolving in real time. Hence, the sound design is intricately woven into your musical expression, guiding you on a journey of continuous discovery and wonder.

Changes in effects are often achieved using presets, expression pedals, and MIDI control. While each method has its own advantages, they can only take you so far. However, the AUTO Series provides a different approach to orchestrating effects, emphasizing playing your instrument.

Each pedal has two automation sources that you control with your performance. The DYNAMICS follows the volume nuances of your playing. It captures the character of your picking style as well as your instrument's loudness and decay. The PITCH tracker, on the other hand, detects note choices, bends, and vibratos. You wield the power to route these automations to any of the four effect knobs, setting the parameters in motion.

Customize the adjustments with the DYNAMICS and PITCH knobs and dedicated mode switches. Adjust the DYNAMICS decay time, introduce glide to PITCH tracking, and tailor the response curves to match your playing style and the desired effect.

Each of the primary effect knobs is paired with a corresponding smaller adjustment knob, also known as an attenuverter. This allows you to precisely dial in the variation amount and direction for each effect knob independently. Imagine the dynamic possibilities – a loud strum on a guitar can turn one knob clockwise significantly, while only slightly nudging another knob in the opposite direction. Explore the subtleties, from gentle parameter shifts to sweeping, full-parameter transformations.


You can play a note to set it as the center pitch by holding both footswitches. For instance, choosing A3 as the center pitch means that the PITCH modulation will activate only when surpassing A3. DYNAMICS features an adjustable volume threshold – automation occurs only with notes louder than the set threshold. You can personalize your effects experience with ease and precision.

FEATURES OF AUTO CHORUS

  • 3 algorithms: CHORUS, ENSEMBLE and FLANGE
  • 4 streamlined controls: LEVEL, DEPTH, RATE, FEEDBACK
  • 3 shapes: SAWTOOTH, SINE, RAMP

EXAMPLES OF AUTO CHORUS

Delayed vibrato

Add slowly increasing vibratos on sustained notes and chords. Set the pedal to CHORUS mode and listen to the WET sound only for a VIBRATO effect. Route the DYNAMICS to the DEPTH knob and set it in the maximum desired vibrato depth position. Increase the DEPTH MODULATION AMOUNT in the counter-clockwise direction to reduce VIBRATO DEPTH on the initial part of each note.

Resonant chorus

Inject a metallic CHORUS resonance into your sound by cranking the FEEDBACK. While this can initially sound appealing, it's an effect you might not want to have constantly on. Route the DYNAMICS to the FEEDBACK knob, set it to the minimum value, and add a little bit of MODULATION DEPTH in the positive range - just a tiny bit to color the attacks.

Accelerating jet engine

FLANGER is known for the effect reminiscent of jet engine sounds. Route the PITCH to both DEPTH and RATE to animate the FLANGER effect as you move up the neck by making it faster and more intense.
