Analog delay and tape echo simulator
From the manual: "The FX96 Echo FX is DOD's latest addition to its arsenal of great pedal effects. The FX96 is an Analog Delay pedal that offers tape delay simulation at your feet. No longer will you have to haul (and handle with care) the bulky Echo tape machines of the past to the gig. And if the "worn out" tape characteristics of the old Echo machines is the sound your [sic] looking for, the FX 96 gives a Tape Quality control for changing the tonal quality of the tape emulation."
