The EMMA Electronic TransMORGrifier is an envelope-controlled filter pedal whose filter sweep is triggered by picking dynamics rather than a manual knob. Its core control, Sensitivity, sets how strongly the input signal's amplitude drives the filter's movement, so softer or harder playing changes the cutoff frequency accordingly. A Decay or Release control determines how quickly the filter returns to its resting state after the note's attack, shaping whether the sweep feels tight and percussive or slow and vocal-like. The pedal also includes a manual filter-frequency adjustment to set the base cutoff point around which the envelope operates, and a resonance or Q control emphasizes the frequencies near the cutoff, producing a more pronounced, synth-like peak. A mode switch may alter the filter's response direction, allowing the sweep to move upward or downward in pitch, and a blend or mix control balances the dry guitar signal with the filtered effect, letting players retain their original tone while adding the dynamic filter coloration. The unit is housed in a compact, rugged enclosure suited for pedalboards, with standard input and output jacks for mono operation.
