Seller's description

Late '70s envelope controlled filter featuring range control and bass/guitar toggle knob. Made in the USA. Adds quacky, auto-wah style movement to guitar or bass, reacting to your playing dynamics rather than an LFO. Simple Range and Bass Toggle controls let you dial in everything from tight rhythmic funk snaps to looser vowel-like sweeps. A long-running part of the EHX lineup, it’s been a go-to for players chasing classic 70s filter textures, like Jerry Garcia, Bootsy Collins and Mike Gordon. 9v pedal power but requires mini-jack adapter (not included) Video: https://youtu.be/2OL0ehCypdA Product Specs Item Number: 40217 Make: Electro Harmonix Model: Doctor Q Envelope Follower Condition: Very Good Finish: Chrome Categories: effects-and-pedals ⇒ wahs-and-filters ⇒ pedal Year: 1970s Made In: United States MPN: 40217
