Alexander Pedals Equilibrium DLX - Tremolo / Harmonic Vibrato


Alexander Pedals

The Equilibrium DLX is our updated vintage modulation pedal - evoking the buttery, sputtery, wobbly sounds of yesteryear,  While the Equilibrium DLX sounds completely vintage, it crams all the "mod cons" into a pedalboard-friendly package.

  • Rate (Level) — Adjusts the rate of modulation from a slow pulse to a rapid flutter.  Turning this knob cancels the Tap Tempo setting.  Holding down the Bypass / Level footswitch lets you adjust the overall output level of the effect.  The Level setting is stored in the memory of the pedal for future use.
  • Depth Â— Controls the amount of modulation from barely perceptible to seasick.
  • Shape Â— Selects one of four waveforms to control the modulation effect:  Sine, Ramp Up, Ramp Down, or Square.
  • Mix Â— Blends between the dry and the modulated signals. 
  • *Hint: For traditional style tremolo, set the Mix knob fully clockwise.
  • Tap Tempo / Division - tap twice to set the modulation rate.  The LED above the Tap switch flashes to indicate the current rate and division.  Hold to toggle between normal-speed (green) and double-speed (red) settings.
  • Remote Tap Tempo Jack - connect a normally-open momentary footswitch to this jack to set the modulation time remotely. Hold down the remote footswitch to change tap divisions.

Mode Toggle:

  • Tremolo Â— Traditional tremolo based on the bias circuits from the earliest tube amps. Use the Shape control to morph from a very soft and smooth tremolo to a much harder burp-burp modulation. 
  • Harmonic Â— Based on the vibrato circuits from the early ‘60s piggyback amplifiers. Blend in the dry signal for a queasy, seasick effect.
  • Vibrato Â— True '50s style frequency vibrato, just like Buddy Holly. Try it with a fast speed and 100% wet mix for the widest vibrato effect.  Mixing in some dry signal makes the vibrato sound more like a phaser or photocell vibe unit.
