Basic overview and features of the JET Eternity Delay
Overview

Overview
Introducing theEternity Delay-our most sophisticated design to date.
The Eternity Delay is engineered with six studio-grade algorithms, six onboard presets (127 with
MIDI), full MIDI control over every knob, switch, algorithm, preset, and bpm with MIDI clock.
Additionally, it features a live mode, preset mode, and kill-dry mode. It also boasts the world's
most advanced tap tempo and stereo analog dry thru.
We've included Junior (JET's) favorite algorithm into the Eternity Delayand named it, JET's
Signature Rhythm Delay (JRD). The JRD is aslapback &analogdual delay algorithm. This algorithm
is not commonly found in other delay pedals, but Junior has used it extensively to create massive
sounding rhythm and lead sounds.
The Eternity Delay features anupgrade to the standardtap tempo. The Eternity tap tempo
averages the BPM based on the number of taps received. This results in extreme accuracy when
MIDI clock isn't available. The tap tempo rate LED automatically syncs itself to the BPM and flashes
on the downbeat of each ¼ note, solving the problem of flashing LEDs that appear to be out of
tempo.

Overview
The Eternity has 6 studio grade algorithms to choose from. Below details the sounds for each
algorithm.
Designed to emulate tape machine delay’s. With sonic characteristics of warm tube saturated
repeats, each repeat gets progressively darker and the speed of the tape reels can fluctuate,
causing artifacts such as wow and flutter. A brand new tape machine will have minor artifacts
affecting the delay repeats. However as it ages, these characteristics tend to be more distinct and
the delay repeats will represent more of these artifacts. Cntrl1 will emulate the tape age, fully
counter-clockwise is like a brand new tape machine. As its rotated clockwise, each repeat gets
darker and the wow & flutter becomes more noticeable.
Bright & clean delay repeats. The Cntrl 1 knob adds some character/grit to your repeats for a less
pristine delay sound. The character/grit is input sensitive, play harder and this will be more
noticeable or play softer for less character/grit.
Designed to emulate the old bucket brigade analog delay’s. Analog delay’s will have signal
degradation on each repeat causing each successive repeat to roll off some high frequency’s. The
Cntrl 1 knob, when set fully counter-clockwise, is a simple and straightforward Analog delay. When
rotated clockwise, the Cntrl 1 knobs adds modulation to the repeats of the delay. The rate and
depth of the modulation is fixed, think of the Cntrl 1 knob as a volume knob for the modulation.
Algorithms
Tape Delay
Digital Delay
Analog Delay

This delay runs two different delay’s with different subdivisions in full stereo and in ping pong (L &
R). Delay 1 is an analog delay which is set by the Subdivision switch and Delay 2 is a fixed dotted
eight digital delay. The Mix knob controls the level of delay 1 and the Cntrl 1 knob controls the
level of delay 2. The subdivision switch affects Delay 1 and is as follows:
1/4 Note Setting
Delay 1 will be set to a 1/4 note with Delay 2 set to a dotted 1/8 note
Dotted 1/8 Note Setting
Delay 1 will be set to the Golden Ratio with Delay 2 set to a dotted 1/8 note
1/8 Note Setting
Delay 1 will be set to an 1/8 note with Delay 2 set to a dotted 1/8 note
This delay is actually three delay’s in one and the subdivision switch selects between the three
different delay’s. The Echo delay is called up when the Subdivision switch is set to the 1/4 note
position. Based on the tap tempo range (approx. 60 - 160 BPM) the Echo delay will range from 333
milliseconds to 125 milliseconds. When the subdivision switch is set to dotted 1/8, this calls call up
the Slap delay. The tap tempo range will go from 125 milliseconds to 47 milliseconds. When the
subdivision switch is set to the 1/8 note position, this calls call up the Doubler delay. The tap
tempo range will go from 63 milliseconds to 23 milliseconds. The Cntrl 1 knob widens the stereo
spread of the ESD delay, at fully counter-clockwise the stereo spread will be off and gets wider as
its rotated clockwise.
Dual Delay
Echo | Slap | Doubler (ESD) Delay
JET Signature Rhythm (JRD) Delay

This delay is not commonly found on other delay pedals however it is a sound that I (Junior “JET”)
have used extensively for creating massive sounding rhythm & lead sounds. This delay is very
similar to the Dual Delay however it is important to not have the delay’s ping pong back and forth.
Delay 1 is an analog delay and the Subdivision switch, Mix, and Repeats knobs all control delay 1.
Delay 2 is a fixed 100 millisecond Slapback delay and Cntrl 1 adjusts the overall volume of delay 2.

Delay

Operating your Eternity Delay
To enter the Global Settings, hold down the Bypass switch when power is first applied to the pedal.
The Mix and Repeats LEDs will be glowing and cycling through various colors. Release the Bypass
switch when the Mix and Repeats knobs turns either solid White or Red (if Kill Dry mode is enabled
the LEDs will be Red). To save your settings and exit the Global Settings, hold down the Bypass
Switch for 3 seconds. The Mix and Repeats LEDs will continue glowing and cycling through the
various colors until your settings have been saved.
Below are the following features that can be adjusted within the Global Settings:
Setting the MIDI Channel
Rotate the Cntrl1 knob, the Bypass LED will flash the number of times that corresponds
to the MIDI Channel. If setting to MIDI Channel 4, the LED will flash 4 times with a 2
second pause and then repeat.
Enable/Disable Kill Dry Mode
Short press the Tap switch, the Mix and Repeats knobs will change colors. If the LED
colors are Red, then Kill Dry Mode is enabled. If the LED colors are White, then Kill Dry
Mode is disabled.
Load a Specific Preset Upon Start-Up
Rotate the Mix knob, the Mix LED will cycle through the Preset colors. Rotate until your
desired Preset is illuminated.
Load a Specific Algorithm Upon Start-Up
Rotate the Repeats knob, the Repeats LED will cycle through the Algorithm colors.
Rotate until your desired Algorithm is illuminated.
Limit the Number of Presets to Scroll Though
Rotate the Filter knob, the Tap LED will flash the number of times that corresponds to
the maximum number of Presets available to scroll through. If setting to 3 Presets, the
LED will flash 3 times with a 2 second pause and then repeat.

Operating your Eternity Delay
Power the Eternity with a 9v DC negative tip power supply, one that is capable of handling up to
300mA of current. Upon powering the Eternity the Mix and Repeats knobs will glow indicating
startup mode. Once the Tap LED begins to flash the Eternity is ready to use. Tap the Bypass switch
to engage the pedal (Live Mode), the color of the Repeats knob indicates the active algorithm and
the color of the Mix LED indicates the cue’d up Preset.
Hold the Bypass switch for 1 second and release to change algorithms.
Light Blue | Tape Delay
Green | Digital Delay
Yellow | Analog Delay
Red | Dual Delay
Pink | ESD Delay (Echo, Slap, Doubler)
White | JRD (JET Signature Rhythm Delay)
To engage Preset Mode, double tap the Bypass switch. This will quickly jump between the delay
used in Live Mode to the delay stored in the cue’d up preset. To disengage Preset Mode and jump
back to Live Mode, double tap the Bypass switch again.
To change presets, tap both the Tap switch and Bypass switch to cycle through the stored presets:
Light Blue | Preset #1
Green | Preset #2
Yellow | Preset #3
Red | Preset #4
Pink | Preset #5
White | Preset #6
While in Preset Mode you can rotate the knobs to see the saved location of each knob in the stored
Using the Pedal

preset. When each knob is rotated, its corresponding LED will flash, and will return back to a solid
color once the knob is rotated over the stored location.
The Mix knob controls the overall loudness of the repeats. Rotating fully counter-clockwise will set
the repeats volume to minimum and fully clockwise to maximum. The Mix knob does not
affect/remove any of your dry signal. In order to get 100% wet delay, you need to engage Kill Dry
Mode.
The Repeats knob controls the number of repeats that will be regenerated from the Eternity.
Rotating fully counter-clockwise sets the repeats to minimum (one repeat) and fully clockwise sets
the repeats to maximum. At maximum settings, the repeats will not self-oscillate.
The Filter knob controls the overall brightness of the repeats. Rotating fully counter-clockwise
allows all frequencies to pass, when rotating clockwise the upper frequencies will be removed.
Rotating clockwise sets the cutoff frequency lower and lower for darker repeats. The Filter knob
does not affect/remove any frequencies from your dry signal.
The Cntrl1 knob varies per algorithm, please reference the Algorithm section for details pertaining
to the Cntrl1 knob for each Algorithm.

The Bypass Switch functions as the main navigation for the pedal, below outlines the functions
attached to this switch.
Short Press
Performing a short press will engage/disengage the pedal. When engaged, the Bypass
LED will illuminate and the delay signal will be heard. This is called “Live Mode”, the
sound of the delay will be heard based on the current settings of each knob, toggle
switch, and the active Algorithm that is illuminated by the Repeats LED.
Double Tap
Performing a double tap will engage/disengage “Preset Mode”. When Preset Mode is
engaged, the Tap LED will illuminate and the delay signal will be the sound that is
saved in the current preset location. The current preset can be identified by the color
of the Mix LED. When Preset Mode is engaged, the saved Algorithm can be identified
by the color of the Repeats LED.
Two Button Press (Tap & Bypass Switches)
Performing a two button press will cycle through the stored presets. Each time a two
button press is performed the color of the Mix LED will change, identify which preset is
active or cue’d up. If the pedal is in Preset Mode, it will cycle through each preset and
the new preset sound will be heard immediately. If the pedal is in Live Mode, you can
cue up which preset will be heard when Preset Mode is engaged.
Long Press
Performing a long press (hold for 1 second and release) will cycle through the active
algorithm. Algorithms can be changed at any time in both Live Mode and Preset Mode
The Tap Switch is dedicated to tap tempo. To set a tempo you must press the tap switch at least 3
times, anything less and the tempo will not update. The tap tempo may take longer to update than
other delay pedals however we feel accuracy is more important than speed. Our tap system is the
most accurate tap tempo on the market and this is achieved by averaging the tempo based on the
number of taps it receives. In other words, the more taps you enter into the Eternity the more

accurate the tempo will be.
Setting the Toggle Switch to the top position will create repeats with a 1/4 note subdivision based
on the tempo that has been tapped in by the Tap Switch.
Setting the Toggle Switch to the middle position will create repeats with a dotted 1/8 note
subdivision based on the tempo that has been tapped in by the Tap Switch.
Setting the Toggle Switch to the bottom position will create repeats with an 1/8 note subdivision
based on the tempo that has been tapped in by the Tap Switch.

Saving a preset is simple and quick. Cue up the current preset location you’d like to save a preset
to (identified by the color of the Mix LED). Change the active algorithm (if desired) and dial in the
settings on the toggle switch and knobs. Once you have a sound that you like, simply hold down
the Bypass Switch for 3 seconds. The Bypass LED will flash rapidly indicating the preset has been
saved.
***To save a preset the pedal must not be bypassed, you can save a preset in either Live Mode or
Preset Mode.

Library of MIDI commands and how to program your Eternity.
MIDI Features and Controls

MIDI Features and Controls
Midi communication to the Eternity conforms to the specification for TRS to Midi adapters issued
by the Midi Association. So what does this mean for me? In order to communicate via Midi you will
need either a 5 pin to 1/4" TRS adapter cable that is wired to the TRS specification, or if you wish
to make your own patch cables, a link to the wiring diagram and the midi specification can be
found here. You can also use a midi box/ hub that converts 5 pin Midi to multiple TRS outputs, like
the Traffic Control from JET or similar boxes from Strymon or Morningstar. You could also use a
compatible Midi controller with TRS midi output's like the Futurist by Matthews Effects or various
controllers by Morningstar.
How to Connect

MIDI Features and Controls
From the factory the Eternity is set to receive Midi messages on Midi channel 1, however this can
be changed upon powering up the pedal. After applying power to the Eternity, hold down the
Bypass switch while the pedal is in startup mode (Mix & Repeats knobs are scrolling thru the color
spectrum). Once the LEDs turn a solid color, release the Bypass switch to enter the Global
settings. Rotate the Cntrl1 knob and the Bypass LED will begin to blink between 1 and 16 times
(depending on which channel is set by the knob). Rotate the Cntrl1 knob counter-clockwise to
decrease the MIDI channel or clockwise to increase the MIDI channel. Once you've reached the
desired channel (i.e. channel 6 means the LED will flash 6 times), hold the Bypass switch to exit
the global settings and to save the Midi channel to permanent memory.
Changing the MIDI Channel

MIDI Features and Controls
You have two options for creating presets. The first option is to use a "smart" midi controller (like
the JET MCX) that can send multiple simultaneous midi messages. Just send individual CC
messages to turn the Bypass switch on, select the algorithm, and set the values for each
knob/toggle switch.
The second option is to use our revolutionary CC Snapshot feature. While in Live Mode, select your
desired algorithm and then set all of the knobs & switches to their desired positions. From there
just send midi CC #28 with any Value from 7 thru 127. The pedal will then take a snapshot of its
algorithm and knob/switch positions, after that the knobs will flash green letting you know the
preset has been saved into permanent memory. To recall this preset, just send a PC message with
the same number used for the Value when sending CC #28.
Example: send CC #28 Value 10 to save a preset in the 10th slot. Send PC #10 to recall the new
preset.
The Eternity can save 127 onboard presets (the first 6 are saved using the pedal and 7 - 127 are
saved with CC Snapshot).
Saving Presets via MIDI
