Here is a vintage 1960s Park Auto-Wah electric guitar effects pedal. The Park Auto-Wah, like many British pedals of the time, was made by Colorsound/SolaSound for Park. It features (3) controls: Speed, which sets the pace of the LFO; Depth which controls the sweep of that filter, and Tone. Like the fantastic Ibanez auto-filter that followed more than a decade later, this Park Auto-Wah is one of the coolest and rarest vintage effects ever made. Produced in extremely small quantities, only several have ever been offered online in the last 10 years. Whether you’re a collector or player, this pedal definitely has its place.
