EH 16 second dly

[Grant Richter]

According to a rep at the EH booth at the
NAMM show the 16 second is next up for reissue
if they can find replacements for some of the
obsolete chips.

One of the best digital delays ever because
it works exactly like a tape delay - change
the clocking rate and change the pitch -
essential for prog and spacerock.
The feedback gain also exceeds 1 so
you can do those slow build sounds
with a pitch sweep at the end.

A completely inadequate power supply though.
And when you get out to 16 seconds your bandwidth
is about 2.5 Khz.
