The J. Rockett Audio Designs Alien Echo is a delay pedal built to recreate the sound of vintage analog bucket brigade tape delays, with randomized modulation that mimics a worn-out tape machine1. It is a compact delay pedal with four knobs and two footswitches, one of which switches the modulation on and off mid-song23.
What it sounds like
J. Rockett describes the Alien Echo as an offering to achieve vintage analog sounds and worn-out tape delay sounds, with modulation that is random and unpredictable, similar to a tape delay3. RockBoard's PedalPedia entry puts it the same way: the pedal aims to replicate vintage analog bucket brigade tape delay tones, with randomized modulation like that of a worn-out tape delay1.
The modulation is not a fixed setting you dial in and leave. Delicious Audio notes that it is foot switchable for on-the-fly effect changes3, and guitar.com's review confirms the two-switch layout: Warble on/off, and effect on/off2.
The controls
The Alien Echo keeps things simple: four knobs and two footswitches2.
| Control | What it does |
|---|---|
| Delay time | Sets the length of the repeats2 |
| Warble | Twists and detunes the repeats in the manner of worn-out tape2 |
| Mix | Blends the delayed signal with your dry signal2 |
| Repeats | Sets how many times the delay repeats2 |
| Tone | Shapes the character of the repeats2 |
The tone control only affects the delay signal, and depending on where it is set, it dictates vintage analog or worn-out tape delay sounds3. Mixing up the Time, Warble and Repeats knobs, Pedal of the Day's reviewer found, produces "an eternity of different aural pleasures"5.
Power and connections
The Alien Echo runs on a 9 volt negative tip adaptor with a 5.5mm x 2.1mm jack, and it can also run from a 9 volt battery5. It uses true bypass switching5.
Size and build
The pedal measures 4.75" x 3"5, in what Pedal of the Day's reviewer called a "narrow but surprisingly thick brushed chrome enclosure" that "looks gorgeous"5.
What reviewers said
Premier Guitar's reviewer summed up the Alien Echo's strengths as "Warm musicality. compact and versatile. easily controllable."4. Guitar.com's review of the pedal highlighted the warble control as the source of its tape-worn character2.

Questions
Does the J. Rockett Alien Echo run on a battery?
Yes. Along with a 9 volt negative tip adaptor with a 5.5mm x 2.1mm jack, the Alien Echo can run from a 9 volt battery, according to Pedal of the Day's review. That makes it easy to try on a board or take to a gig without a dedicated power supply.
Is the Alien Echo true bypass?
Yes. Pedal of the Day's review lists the Alien Echo as having true bypass switching, so when the effect is off, your guitar's signal passes through the pedal without going through the delay circuit.
What does the Warble knob do on the Alien Echo?
The Warble control shapes the pedal's randomized modulation. Guitar.com's reviewer described it as twisting and detuning the repeats in the manner of worn-out tape, which is central to the pedal's aged tape echo character. Modulation can also be switched on and off with a footswitch.
How big is the J. Rockett Alien Echo?
Pedal of the Day's review gives the dimensions as 4.75 inches by 3 inches, in a narrow but thick brushed chrome enclosure. That compact footprint suits crowded pedalboards.
Can the Alien Echo's modulation be switched off with a footswitch?
Yes. Delicious Audio notes that modulation is foot switchable for on-the-fly effect changes, and guitar.com's review lists two footswitches: one for Warble on/off and one for effect on/off.
