FACTOIDS & TRIVIA
Ampeg entered the outboard
reverb unit market in 1961 with the Echo Satellite and in 1963 with the
Echo Jet. Unlike reverb units from Fender, Premier, Danelectro, and
Alamo, the Echo Jet followed the approach of Gibson and Guild; namely,
build an outboard reverb unit that could also be used as a stand alone
amp. As its name implies, the Echo Jet is similar in size and sound to
Ampeg’s Jet amplifiers. However, the EJ-12 lacks the Jet’s tremolo. The
Echo Jet’s strong suit is its ability to stretch the sonic potential of
a non-reverb amp. The EJ-12 accomplishes this not only by adding lush
speaker driven-type reverb to the sonic mix, but by physically
separating the reverb speaker from the dry signal amp’s speaker. This
signal separation of up to 8 feet combined with the slight delay of
speaker driven reverb yields a quasi-stereo effect. The amp shown here
was made during the last year of production and utilizes the second
version of the Echo Jet circuit (EJ-12-A). A third version of the
circuit (EJ-12-D) was made for a very short period in late 1965.
