Echoplex Digital Pro

RackmountDigital

Back in 1994, this digital take on the legendary tape Echoplex brought looping into the modern era, letting performers capture and manipulate audio with RAM-based precision instead of fragile tape.

It records at 16-bit 44.1kHz quality into expandable RAM—starting at 50 seconds and upgradable to 200 seconds using standard SIMM chips—for seamless real-time looping, overdubbing, and playback. The front panel packs four level knobs for input, output, mix, and feedback, plus a 6-character display, row indicator lights, and eight multifunction buttons with status LEDs for instant access to modes like Reverse, Half Speed, Multiplay, and Undo. Stereo ins and outs handle mic to line levels, with full MIDI sync, tempo control, and footswitch compatibility via an EFC-7 pedal for hands-free operation. Back panel keeps connections simple: audio jacks, MIDI in/out/thru, and power.

Loopers still swear by its rock-solid reliability and glitch-free performance, especially with Loop IV upgrades adding 16 loops, granular SUS commands, and expanded sync options—though some note the lack of built-in effects like pitch shift keeps it pure for layering. A true performer's secret weapon from Oberheim's Gibson days.
