Faithful circuit to the original from the 1960's. The most important element of any wah wah pedal is its voice. The Thomas Organ Company and Jen Electronica used a special component called a Halo Inductor to give the original Clyde McCoy pedals their highly-coveted smooth vocal quality. Because of the way those original Halo inductors were built, however, they often added undesirable microphonic noise. Our engineers created the Dunlop HI01 Halo Inductor to solve this problem, updating the original design with a stabilized cup core to preserve the unique Clyde McCoy sound while minimizing unpleasant microphonics. Catch that vibe! • MFSKU CM95 • UPC 710137041608
