Envelope filters of this type respond to pick attack, compressing and sweeping the filter cutoff in real time. The result is a wet, vocal, quack-heavy filter effect that sits well under rhythm playing and works equally on bass or guitar. This is an analog circuit with the immediate, organic response that defines the format.\u003c\/p\u003e\n\u003cp\u003eThe Electra 870 series was produced by Electro-Harmonix for St. Louis Music Supply Co. in the mid-1970s, effectively rebadging EHX designs under the Electra name for distribution through that retail channel. The Model 871 corresponds to the Doctor Q envelope follower circuit. These were sold in modest numbers and never achieved the wide distribution of the standard EHX line, which makes them genuinely scarce today. For collectors, they represent a specific and documented chapter in the OEM history of early Electro-Harmonix production. \u003ca href=\"https:\/\/www.maharsvintageguitars.com\/pages\/sell-vintage-guitars\"\u003e\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eBe sure to check out the other cool guitar related stuff on our site!\u003cbr\u003e\u003ca title=\"Vintage and used effects pedals at Mahar's Vintage Guitars\" href=\"https:\/\/www.maharsvintageguitars.com\/collections\/effect-pedals\"\u003eVintage \u0026amp; Used Effects Pedals\u003c\/a\u003e — \u003ca title=\"Vintage and used Fender guitars at Mahar's Vintage Guitars\" href=\"https:\/\/www.maharsvintageguitars.com\/collections\/vintage-fender-guitars\"\u003eFender Electric Guitars\u003c\/a\u003e — \u003ca title=\"Vintage and used Gibson guitars at Mahar's Vintage Guitars\" href=\"https:\/\/www.maharsvintageguitars.com\/collections\/gibson-guitars\"\u003eGibson Electric Guitars\u003c\/a\u003e — \u003ca title=\"Vintage and used guitar amplifiers at Mahar's Vintage Guitars\" href=\"https:\/\/www.maharsvintageguitars.com\/collections\/amps\"\u003eVintage \u0026amp; Used Amplifiers\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eShipping Policy\u003c\/b\u003e\u003cbr\u003eBy completing your purchase you are agreeing to this shipping policy.
