Echoplex uses magnetic tape and a moving-head design to create echo and delay effects of various
lengths. While they aren’t pedals, the tube-based EP-1 and EP-2 models were among the first delay
units on the market, and many effect connoisseurs still consider them the standard that every other
delay is measured against. The Echoplex remained available in the 1970s in the form of the solid-state
EP-3 and EP-4 models.
Speaking of the 70s, it was the era when effects really started to gain widespread popularity with
musicians in general and guitarists in particular and Maestro was in the thick of it, offering several
classic units, including some models that were designed by the legendary Tom Oberheim. Tom was
responsible for both the first Ring Modulator pedal (the Maestro RM-1), and the Maestro PS-1, the first
Phase Shifter pedal. Oberheim’s involvement with Maestro ended in 1973 when Gibson’s then-owner
Norlin acquired Moog, and Moog took over the design and manufacture of Maestro effects pedals,
which they continued to do until Norlin discontinued production of Maestro pedals in 1979.
Now Gibson is bringing Maestro back and is committed to the same spirit of excellence, innovation,
and quality that the brand represented in its first incarnation. The pedal in your hands is proof of
Gibson’s dedication to excellence in effect pedal innovation. Please continue reading the rest of
this manual to learn about its features and operation, as well as important safety, maintenance, and
warranty information.
There’s a whole universe of sonic possibilities out there. We invite you to participate in a new era of
exploration and discovery with Maestro.
