Echoplex

This article is about a guitar sound effect. For the music venue in Los Angeles, see Echoplex (venue). For the concept in computer telecommunications, see echo (computing).

Echoplex EP-2

The Echoplex is a tape delay effect, first made in 1959. Designed by Mike Battle,^[1] the Echoplex set a standard for the effect in the 1960s and was used by some of the most notable guitar players of the era; original Echoplexes are highly sought after.

The original tube Echoplex

The predecessor of the Echoplex was a tape echo designed by Ray Butts in the 1950s, who built it into guitar amplifiers, including those of Chet Atkins and Carl Perkins. Tape echos work by recording sound on a magnetic tape which is then played back; the tape speed or distance between heads determine the delay, while a feedback variable (where the delayed sound is delayed again) allows for a repetitive effect.^[2]

In the 1950s, Maestro was a leader in vacuum tube technology. It had close ties with Gibson, and often manufactured amplifiers for Gibson. The first Echoplex, which utilized vacuum tubes, was designed by electronics technician Mike Battle and guitarist Don Dixon and marketed in 1961. Their big innovation was the moving head, which allowed the operator to change the delay time. In 1962, their patent was bought by a company called Market Electronics in Cleveland, Ohio. Market Electronics built the units and kept designers Battle and Dixon as consultants; they marketed the units through distributor Maestro, hence the name, Maestro Echoplex. The first tube Echoplex had no number designation but was retro-designated the EP-1 after the unit received its first upgrade. The upgraded unit was designated the EP-2.^[1] These two units set the standard for the delay effect, with their "warm, round, thick echo."^[3] The Echoplex effect is "still a classic today, and highly desirable for a range of playing styles...warm, rich, and full-bodied."^[4] The delay could be turned off and the unit used as a filter, thanks to the sound of the vacuum tubes; this is how Andy Summers uses it, for instance.^[5] A later model was called the EP-2.^[1]

While Echoplexes were used mainly by guitar players (and the occasional bass player, such as Chuck Rainey, or trumpeter, such as Don Ellis), many recording studios also used the Echoplex.^[6]

The Solid-state Echoplex

EP-3

Market Electronics held off on using transistors while other companies made the transition. Nevertheless, in the late '60s they set Battle and Dixon to the task of creating the first transistor version of their product. Once the two were satisfied, beginning in the 1970s, the solid-state Echoplex was offered by Maestro^[3] and designated the EP-3, but Mike Battle, unhappy with the sound of the EP-3, sold his interest in the company.^[1] This unit offered echo, sound-on-sound, and a number of little convenience tweaks. Having been produced from 1970 to 1991, this unit enjoyed the longest production run of all the Echoplex models. Right about the time of the public introduction of the EP-3, Maestro was taken over by Norlin industries, then the parent company to Gibson Guitars.

EP-4

In the mid-1970s Market created an upgrade to the EP-3, designated the EP-4, adding features such as an LED input meter and tone controls and dropping the sound-on-sound feature. The EP-4 has an added output buffer to help improve impedance interfacing with other equipment. A compressor board based on the CA3080 Transconductance Amplifier was added to the record circuit of both the EP-3 and EP-4 models for a short while after the EP-4 model was introduced and then the compressor board was dropped from both the EP-3 and EP-4 models. The EP-3 model was also offered for sale alongside the EP-4 model after the EP-4 was introduced. ^[7]

Battle's final consulting with Market yielded the EM-1 Groupmaster, which offered a four-channel input mixer section and a mono output section. In the mid-'70s Maestro also created the ES-1 Sireko (pronounced "Sir-Echo"), a simplified, echo-only unit with a bin-loop cartridge system.^{[citation needed]}

End of the brand

Gibson Echoplex Digital Pro

At the end of the '70s, Norlin folded and their Maestro brand and Market Electronics was forced to find another distributor for their products. They found that distributor in Harris Teller, a Chicago musical wholesaler. Units built for Harris Teller carried an Echoplex badge that omitted the Maestro name. In 1984, Harris Teller bought out the Echoplex name and all the back stock of Echoplex parts from Market Electronics. Harris Teller used the back stock to assemble reissues of the EP-3, EP-4, and tube EP-2 (which they designated the EP-6t). In 1991, the thirty-year run of electro-mechanical Echoplex production finally came to an end. Towards the middle of that decade the Echoplex brand was purchased by Gibson and applied to its line of digital looping units,^[8][9] one of which was sold under the Oberheim brand as the Echoplex Digital Pro.^[10]
