The Equilibrium takes us back to a time when cars had fins like rocket ships and guitar amps were simple circuits that sounded pure, awesome — and modulated.


Rate — Adjusts the rate of modulation from a slow pulse to a rapid flutter.

Depth — Controls the amount of modulation from barely perceptible to seasick.

Shape — Tweaks the waveform from a rounded sine wave to an abrupt square.

Mix — Blends between the dry and the modulated signals. 

*Hint: For traditional style tremolo, set the Mix knob fully clockwise.

Mode Toggle:

Tremolo — 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 — Based on the vibrato circuits from the early ‘60s piggyback amplifiers. Blend in the dry signal for a queasy, seasick effect.

Vibrato — True '50s style frequency vibrato, just like Buddy Holly. Try it with a fast speed and 100% wet mix for the widest vibrato effect.  

Bypass Switching:

The Equilibrium features true bypass switching using a latching relay and a soft-touch bypass footswitch.  The Equilibrium will power on in either bypass mode or effect mode (useful if you are using the pedal with a remote bypass switching system.)  Hold the footswitch at boot to toggle between bypass and effect startup modes.  The pedal remembers your settings when the power is removed.

Note: certain early Equilibrium pedals have a mechanical 3PDT bypass switch rather than the relay switching.  Relay equipped pedals blink the LED twice rapidly at power-on.

Power Supply:

The Equilibrium requires a 9V DC power supply with a 2.1mm pin, center negative.  The Equilibrium is not designed to be powered on supplies higher than 9V and does not use a battery.  The Equilibrium should work fine on a multi-pedal "daisy chain" connector, but if you encounter excessive noise or hum try a separate power supply.  The Equilibrium requires approx. 60mA.
