Pedal Map

Inspire pedal map


We recommend that Inspire be placed after your preamp or drive pedals but before any delay-based effects (echo, reverb). If you are using the overdrive channel of your amplifier, the best result will be achieved by placing this effect in the effects loop.

The POWER JACK accepts a standard (5.5 mm OD x 2.1 mm ID) center-negative pedal power adapter (not included). The power adapter must be between 9 V and 12 V and capable of supplying at least 100 mA.

Inspire monitors the voltage from your power adapter and will notify you if:

  • The voltage is too low, the LED blinks twice per second. Bypass will be enabled to prevent any unwanted behavior due to insufficient voltage.
  • The voltage is too high, the LED blinks five times per second. The voltage will be internally limited to protect the pedal.

The FOOT SWITCH bypasses the effect. The LED lights when the effect is active. Bypassing the effect does not turn off power to the pedal.

Inspire implements relay bypassing (i.e., “true bypass”). This is the most appropriate type of bypass for this effect in most cases.

 The input and output connections are independent. You may—for example—use a mono input with stereo outputs or stereo inputs with a stereo TRS output.

The INPUT JACKS (right side) accept inputs directly from your instrument, amplifier effects loop output, or other effect pedals via standard 1/4” (6.35 mm) phone connectors.

  • Input 1 only accepts a mono input.
  • Both Inputs 1 & 2 accept a stereo input.
  • Input 2 only accepts a stereo TRS input.

Important: Inputs 1 and 2 should not be used with two discrete signals, such as two different instruments.

The OUTPUT JACKS (left side) supply output to another effect pedal, an amplifier, or effects loop return via standard 1/4” (6.35 mm) phone connectors.

  • Output 1 only supplies a summed mono output.
  • Both Outputs 1 & 2 supply a stereo output. Using both outputs creates a stereo signal from a mono input.
  • Output 2 only supplies a stereo TRS output.



The classic tri-chorus effect.

Inspire tri suggested settings


Two tri-chorus effects are paralleled for an ultra-dense effect.

Inspire hex suggested settings


Two tri-chorus effects in series create a rich, lush effect.

Inspire tri2 tone suggested settings


A tri-chorus and a tri-vibrato in series makes for a complex sound.

Inspire tri2 vibe suggested settings


Low-frequency tri-chorus and high-frequency tri-vibrato—more subtle than Tri2 Vibe, this effect works well with overdrive.

Inspire hi/lo vibe suggested settings


Low-frequency detune and high-frequency tri-chorus is even more subtle and sounds great with heavy overdrive.

Inspire hi/lo detune suggested settings


Tri-chorus plus detune—for the ultimate in lush 80’s chorus tones.

Inspire detune suggested settings


Tri-chorus plus stereo echo is a classic combo.
