I first heard one on Santana's Lotus and then in some of Miles Davis' 70's stuff. From the first time I heard it I wanted that sound. It has three tape heads on it and a fader to change the delay rate. You can use it as a delay pedal or flip a switch and it will play a 4 « tape loop that you can jam over and layer parts onto. Get that going for twenty-four minutes or so and you've got a regular psychodelic freakshow. Steve Kimock told me that they were originally used in K-marts for the "Blue Light Special," if you wanted to have it play every 4 « minutes, turn the fader down; more often than that and turn it up. A few years later Charlie Hitchcock, guitar player for the band Particle, told me to plug into the Echoplex first and then to take the output into the amp I'm playing, using it as asort of pre-amp, to get a real nice tone. Boy was he right! When New Primitives opened for the Neville Brothers, I used the "small" set up as I call it: Les Paul into the Echoplex into the Sano. After the show, Art Neville pulled me aside and asked, "Where you find one of them at? I've been lookin' for one of them for years!" I told him he could use it onstage but he said, "I'd have to remember how to use it." We talked and I got him to sign it for me. The Echoplex is so much fun and one of my favorite sounds and pieces of gear.
