J. Rockett APE Review

J. Rockett APE Review

Liven up your lame digital delay with the ultimate EP-3-style booster.


Enables creative application of EP-3 preamp color. Echoplex-style 22V power creates headroom and oxygenates space between repeats.

Generates ugly with some digital emulation of analog overdrive.


J. Rockett APE


Ease of Use:



Recorded with Fender Telecaster, blackface Fender Vibrolux, and Boss DD-5 recorded via Shure SM57 and Apogee Duet.

A.P.E. recorded in "loop" mode with record level and repeats manipulated in real time.

On one hand, J.Rockett's APE (Analog Preamp Experiment) is a pedal with a simple mission: make antiseptic digital delay sound enormous and organic with Echoplex EP-3-style preamp color. But with series and send/return configuration options, enhanced EQ and saturation shaping control, and the ability to add variable gain and distortion to repeated notes, the APE is much more (and much more fun) than a simple one-knob boost in front of your delay.

Some extra character in the preamp tone is enabled by the authentically Echoplex 22-volt power. It gives the preamp more color and headroom, which gives the APE's dual-function knobs extra range and sensitivity.

Some extra character in the preamp tone is enabled by the authentically Echoplex 22-volt power.

In series operation, the repeats knob becomes a treble control, while the mix and “rec" knobs become output and gain controls, respectively. In send/return or “loop" mode, the repeats and mix knobs replace your delay's feedback and mix controls, while the gain control adds gain and saturation to the delayed notes.

While APE is an unorthodox approach to adding EP-3 shadings, it does a superlative job of generating authentically Echoplex-like preamp distortion and responsiveness. It also enables many more creative, almost painterly, approaches to coloring not just your delay tones, but also the spaces in between. APE is truly unusual, but awesome.

The accomplished guitarist and teacher’s new record, like her lifestyle, is taut and exciting—no more, and certainly no less, than is needed.

Molly Miller, a self-described “high-energy person,” is fully charged by the crack of dawn. When Ischeduled our interview, she opted for the very first slot available—8:30 a.m.—just before her 10 a.m. tennis match!

Donner andThird Man Hardware’s $99, three-in-one analog distortion, phaser, and delay honors Jack White’s budget gear roots.

Compact. Light. Fun. Dirt cheap. Many cool sounds that make this pedal a viable option for traveling pros.

Phaser level control not much use below 1 o’clock. Repeats are bright for an analog delay. Greater range of low-gain sounds would be nice.


Donner X Third Man Triple Threat


A huge part of the early White Stripes mystique, sound, ethos, and identity was tied to guitars and amps that, at the time, you could luck into for cheap at a garage sale. These days, it’s harder to score a Crestwood Astral II, or Silvertone Twin Twelve with a part-time job in the ice cream shop. Back in the late ’90s, though, they were a source of raw, nasty sounds for less than a new, more generic guitar or amp.
