Like most tape echo units of this vintage, there is a some tape noise; however the ratio of signal to noise is makes it somewhat negligible.


   The 1970's Maestro Echoplex EP-4 Model Echo Effect , made in Willoughby, Ohio, Black Tolex finish.  The Maestro Echoplex is the delay unit that set the standard for these effects, and to many still has never been bettered. The Echoplex emerged from Ohio in the early 1960s, coming on the heels of the 1950s Echosonic amplifier (which had the tape unit built in) and the California-made Ecco-Fonic which was portable but proved glitchy in operation. When it was first built, the original tube-driven Echoplex was not only far more reliable in operation than earlier attempts, but great-sounding as well. Designed primarily by Mike Battle, the Echoplex was originally built and distributed by a small company called Market Electronics in Ohio. CMI-Gibson's Maestro division later took over the marketing and distribution, although the units were still built in Ohio. Fairly compact and housed in a sturdy box, the Echoplex was the first truly gig-worthy tape echo and became a very popular item, as crucial to many '60s and '70s performers as their guitar and amp.

  The Echoplex subsequently went through several iterations, from the classic Tube EP-2 to becoming a solid-state design in the early '70s called the EP-3. By the mid-1970s, Market created an upgrade designated the EP-4. This was the final variant and included several design changes, some better than others.
