Chapter 1 - OVERVIEW
In this second rendition, we’ve completely overhauled the original design of the
pedal to come up with a unique concept that packs a whole lot of useful features
and sound possibilities, whilst retaining the compact footprint. New features in-
clude presets capability, 6 new variation modes, and stereo inputs / outputs. The
overall delay algorithms have also been redesigned and improved.
Clockwork Delay V2 offers standard delay mode plus six variation modes. The
variation modes includes Tape, Lo-Fi, Ambient, and Multi-Head (Multi-Tap)
delays.

you’re in primary set) or between H2, H3, and H4(when you’re in secondary set)

Chapter 2 - Operation
All features and operations of the pedal are accessible through the 2 footswitches.
Operation of the footswitches have been carefully designed to keep things as
simple and intuitive as possible.
Switching between Standard and Variation modes (T.L.A / H2.H3.H4)
1. Press both footswitches simultaneously.
Don’t worry about doing this while playing live, the state of variation can be stored
in presets. Position of the Variation selector switch determines which mode gets
activated (this information is also stored in presets).

Switching between primary and secondary Variation Set
Primary set : T.L.A‐Tape, Lo-Fi, Ambient
Secondary set : H2.H3.H4‐2-heads, 3-heads, 4-heads
(Multi-Head / Multi-Tap delay)
Only one set can be activated at a given time.
To go back and forth between the two variation sets do the following :
1. Press and hold both footswitches until the Variation LED changes
its color and flashes 3x.
Saving a preset
1. Press [Select-Tap / Variation] to select the desired preset location.
2. Press and hold [Preset / Bypass] until the Engage LED flashes.
Loading a preset
1. Press [Select-Tap / Variation] to select the desired preset location.
2. Press [Preset / Bypass] to load the selected preset.
Presets are selected by going through each location in the ‘Up’ direction (1, 2, 3,
…), while going trough these steps the sound does not get updated until selection
is confirmed by pressing [Preset / Bypass].
Bypassing or Engaging the pedal
1. Press [Preset / Bypass].
When the pedal is in bypassed state, the tempo indicator (orange LED) is off.

Each variation set has its own preset space : so you have 4 available presets
when using the primary variation set, and another 4 presets when using the secon-
dary variation set.
T . L . A H2. H3. H4
Preset 1 Preset 1
Preset 2 Preset 2
Preset 3 Preset 3
Preset 4 Preset 4
For example, you can have preset arrangement like this :
T . L . A H2. H3. H4
Standard (slow mod) H2(pattern I)
Standard (medium mod) Standard
Tape H3(pattern I)
Lo-Fi H4(pattern II)
Let’s say the current sound is Standard(slowmodulaton),to switch to the H4
(patternII) sound do the following :
1. Switch to Secondary variation set.
2. Select preset location 4.
3. Confirm the selection.

Chapter 3 - Tap Tempo Function
The delay time can be set in relation to the tempo of the music by tapping on the
[Select-Tap / Variation] footswitch. Recall that the same footswitch is also used to
select preset locations, so how can we engage tap-tempo function without inad-
vertently making preset selection?
Note that whichever preset location you’re currently on, it takes a maximum of 3
moves to get to any other preset locations. Let’s say you’re on preset location 1,
then it takes 3 footswitch taps to get into preset location 4. Tapping the footswitch
one more time will take you back to where you started (the current preset loca-
tion).
With this consideration in mind, we’ve programmed the pedal so that the tap-
tempo function is engaged if more than 3 footswitch taps is registered. In other
words, you must tap at least 4x to initiate the tap-tempo function. The new
delay time will be updated immediately after the 4th tap.

Subdivision (tap-ratio)
When using the tap-tempo function, you can use the TIME knob to select one of
the four subdivision options. The TIME knob is partitioned into 4 region, where
each region represents a subdivision.
* Note that the subdivision setting is only relevant when using the tap-tempo func-
tion.

Tips : Select “Quarter-note” if you want the echo interval to match the tap interval.
Select “8th-note” if you want the echo interval to be half the tap interval.

Chapter 4 - The Algorithms
Standard
This is a pristine digital delay with modulation. A touch of tone-shaping is applied
to keep the repeats from being ‘sterile cold’, while retaining clarity and definition.
Maximum delay time is 1000 ms (1 second).
PARAM knob is partitioned into 2 regions : the first half constitutes slow modula-
tion rate and the second half constitutes medium rate. The modulation Depth is
fully adjustable within each region (modulation depth increases as the knob is
turned clockwise). Thus you have modulation with adjustable depth and a choice if
two different rates.

The Algorithms
Lo-Fi
This variation mode has a special voicing that mimics that of an analog delay. The
warm and lush repeats work great to thicken your guitar sound without getting in
the way of the dry sound. Maximum delay time is 1000 ms (1 second).
PARAM knob is partitioned into 2 regions : the first half constitutes slow modula-
tion rate and the second half constitutes medium rate. The modulation Depth is
fully adjustable within each region (modulation depth increases as the knob is
turned clockwise). Thus you have modulation with adjustable depth and a choice if
two different rates.

The Algorithms
Tape
This mode is an emulation of the tape echo system that produces band-limited
echoes with a touch of saturation and delay time variation.
PARAM knob is partitioned into 2 regions : the first half constitutes normal stereo
and the second half constitutes ping-pong stereo. Feedback resonance is fully
adjustable within each region (resonance increases as the knob is turned clock-
wise).
* Stereo setup is required to hear the effect of ping-pong configuration.
