The Echo Fix EF-P3 Chorus is an analog BBD-based chorus by an Australian company known for high-end multi-head tape echo machines.

It’s a rather standard chorus/vibrato built with the best possible components and featuring controls with extended range and increased internal voltage for extra dynamic range.

It features a footswitch that removes the clean signal from the path, in essence switching from Chorus (direct On) to Vibrato (direct Off, i.e. full wet).

The Waveshape knob is the only one that needs a little explanation: it shapes the LFO wave from Sine to Triangle. The Resonance control increases the intensity of the effect.

An extra touch is represented by the rather unique multi-LED lights that light up in patterns according to the settings.
