Riddle

Electro-Harmonix designed the Riddle as a guitar-specific envelope filter. Q-balls technology adapted for six-string use.

Range and Q controls shape the filter sweep character. Sensitivity adjusts how the envelope responds to your playing dynamics. Works best with clean or mildly overdriven signals.

True bypass switching. Compact enclosure fits your board. For guitarists who want envelope filter funk.

Envelope filter voiced specifically for guitar frequencies.
