For an 8-track based unit, the EM-808D has it all: multiple inputs, tone controls, back-lit VU meter, plus the ability to output a 100% wet signal. You can’t really ask for anything more from this kind of technology… Its limitations are the same as every other 8-track delay: one head only, short delay time and low fidelity at slow tape speeds. Regardless, 8-track delays have a charm of their own: low wow & flutter, plus a very peculiar way of distorting signal that makes them extremely useful for certain applications. The EM-808D does a great job at all of this. This unit, along with the Kastam SS-102 (they are basically the same units), are my two favorite 8-track delays.
