Description

Edit description

The stereo version of the P-1220. This DIY delay line or phaser/flanger from the June 1976 issue of Popular Electronics might have faded into obscurity if not for it being the basis of the Erickson Audio Research PFL-1 Pro Flanger, best known for its use on Heart's "Barracuda".
