Electro Harmonix ELECTRIC MISTRESS Deluxe Flanger Filter Matrix Green Serie 1979 - 220 Volts

From 1979, this beauty of a pedal is a true classic, and in a rare green finish. Use it to recreate the ethereal textures heard on Axis Bold as Love, or blaze your own sonic trail with this amazing pedal. The first mode (flange) can go from subtle swirling textures to over-the-top solar flare sweeps. The second mode (filter matrix) allows you to freeze the modulation of the flange at any point

The Electric Mistress' array of critically notched and tuned filters gracefully sweep the sound spectrum, creating shimmering, ethereal passages that are truly out of this world. Exclusive "Filter Matrix" mode disengages the automatic sweep, allowing manual positioning of the filter bank to achieve chime-like metallic tones and other unique effects.
