This stomp box reasonably emulates the classic Binson Echorec rotary plate delay effects unit. Superficially resembling a tape delay, the original Binson Echorec produces its unique sound by pushing the sound through a preamp circuit and what can best be described as a rotary oilcan reverb tank, consisting of spinning plate inside a reverberation drum. The Binson Echorec can be configured anywhere from a subtle slap back or "spank" to a complex lingering echo trail, and it's peculiar sound became a mainstay of psychedelic and some progressive music. If you've ever heard "A Saucerful of Secrets", that's a Binson Echorec you're hearing. While not a perfect match, this particular stomp box circuit is remarkably close, even emulating the subtle hiss and ring of the spinning plate with the right adjustment, and it actually has a little more versatility than the original in that the virtual spinning plate has an adjustable angular velocity, while the original Binson did not. I highly recommend this particular effect, and it pairs well with other time effects such as a plate reverb or even a tape echo.
