Effect list
Effect type: ANALOG
This models an ANALOG DELAY using a bucket-brigade
device (BBD), which is distinctive for its warm distorted
sound.
1. Standard: Analog Delay
This setting reproduces distorted and irregular pitches
that occur in the analog circuit.
2. Vintage: Saturated Delay
This setting controls the distortion that occurs in the
analog delay circuit.
3. Custom: Stereo Analog Delay
This sets the delay time on the left and right separately.
In any setting, the feedback volume on the right is
automatically adjusted and a balanced stereo effect can
easily be obtained.
Effect Type: TAPE
This effect models an analog tape echo. The echo is
produced from the playback head and the delay time
changes and sets the speed of the motor.
1. Standard: Echo Plus
This models an analog tape echo with a high reputation.
2. Vintage: Tube Echo
This models a tape echo with a vacuum tube preamplifier
effect. The preamplifier effect is also applied to dry
sound.
3. Custom: Multi Head
Models a three-head tape echo. The echo produced from
each head contains a feedback loop where a complex and
warm multi-tap echo effect can be obtained.
Effect Type: DIGITAL
This is the DelayLab’s original delay.
1. Standard: Stereo Digital Delay
This setting is a delay where the delay time can be set to
the left and right separately.
The amount of feedback and tone of R Delay will be
automatically adjusted so that the damping time of L and
R delay are in equal.
2. Vintage: Lo-Fi Delay
This setting models a popular digital delay from the 80s.
At the beginning of the digital delay age, large amounts
of memory were not available as they are now, and sound
quality improvements were achieved by falsely changing
the bit resolution according to the input level.
Therefore, the delay contains unique characteristics in the
formation of sound attenuation and the attack sound.
The lower the sampling frequency gets, the more aliasing
noise increases. The lower the bit resolution gets, the
more quantizing noise increases.
3. Custom: Pitch Shifting Delay
This setting is a delay that arranges the pitch shifter in a
feedback loop. If feedback is increased, the sound will be
shifted up or down with each repeat.
Also, if feedback is set to 0, the delay time to 1 ms and
pitch to -0.2 to +0.2, you can obtain a detune effect.

16
VOX DelayLab Owner’s manual
Effect Type: MULTI TAP
This setting is a delay that contains multiple outputs that
can obtain various effects.
1. Standard: Multitap Delay
For this setting, modulation is applied to each of the 3
taps. If the delay time is lowered to 150 ms, feedback is
set to 0 and the depth is increased. It can also be used as a
3-phase chorus.
2. Vintage: Rhythmic Delay
Delay that contains various rhythms and patterns.
)Page 83 “Rhythm pattern”
3. Custom: Multitap Filter Delay
This setting is a complicated delay effect that is achieved
by applying filters to the delay output of each of the 3
taps.
Effect Type: DYNAMIC
This is a delay that changes the quantity of an effect
according to the guitar input level.
1. Standard: Ducking Delay
When a guitar is played strongly, the delay sound volume
decreases automatically to highlight the phrase.
2. Vintage: Sweep Delay
With this setting, you can control the delay time with the
Envelope and create unique flanger effects if the time is
minimized and the feedback is increased. You can also
obtain unique modulation effects that cannot be obtained
by LFO, even if the time is set as normal.
3. Custom: Distorted Delay
This is a delay with a distortion circuit arranged in a
feedback loop. You can use it in unique methods such as
a unison performance by lowering the feedback setting or
as a noise generator by raising the feedback setting.
Effect Type: DUAL
You can use the delay of both the left and right
simultaneously.
1. Standard: Parallel Delay
This setting arranges the two delays in parallel.
2. Vintage: Series Delay
This setting arranges short delays at an earlier stage and
usual delays at later stage in a series. You can produce a
doubling effect with the delay at an earlier stage.
3. Custom: Dual Band Delay
This setting arranges the Lo Band Delay that is applied
with low frequency and the Hi Band Delay that is applied
with high frequency in parallel.
TIP: In Parallel Delay and Dual Band Delay, the
amount of feedback of DELAY2 (Hi Band) will be
automatically adjusted so that the damping time
of DELAY1(Lo Band) and DELAY2 (Hi Band) are
in equal. By setting 2 delay times separately, you
can obtain a rhythmical effect. In the BPM mode,
try setting one end of the Sync Note to 1/8 and the
other end of the Sync Note to 3/16.

17
Effect Type: MODULATION
You can add modulation effects to the delay sound.
1. Standard: Modulated Delay
With this setting, modulation is applied to the delay time.
You can use it as a chorus and flanger by setting a short
delay time.
2. Vintage: Filter Delay
This setting is a delay that has a filter.
3. Custom: Phaser Delay
This setting is a delay that has a phaser arranged in the
feedback loop. You can produce complex sound images
by increasing the feedback.
Effect Type: STEREO
This is an effect that expands mono guitar inputs to the left
and right. Use this effect with stereo outputs.
1. Standard: Cross Delay
This setting is a delay that performs cross feedback from
left to right and right to left.
2. Vintage: Panning Delay
This setting is a delay that performs panning of the
normal position of the delay sound from the left and
right.
3. Custom: Left Center Right Delay
This setting is a multi tap delay that outputs 3 taps to the
left, center and right.
Effect Type: AMBIENT
The sound is delayed, and then a reverb effect is additionally
applied, producing a deeply reverberant sound.
1. Standard: Space Delay
With this setting you can obtain unheard of sounds that
expand into space.
2. Vintage: Reverb Delay
This setting achieves the sound of a large space with
rebounding reflections of the original tone.
3. Custom: Early Reflections Delay
This is a delay that adds the initial reflected effect.
You can apply a reverberant sound without drastically
changing the tone quality.
TIP: Space Delay and Reverb Delay are effects combined
with 3 factors including reverb, delay and pitch
shifter. If TIME is shortened, PITCH is set to +12 and
FEEDBACK is increased, you can obtain reverberant
sounds similar to string sounds. If TIME is 10 ms or less,
PITCH is 0 and FEEDBACK is raised, natural reverb is
produced that is suitable for a broad range of music.
Effect Type: REVERSE
This is a reverse delay that plays the delay sound in the
reverse direction. To change the head position of the reverse
delay play, set FWD/RVS to (FWD 100%) and raise the
parameter of the FWD/RVS to the preferred timing.
1. Standard: Reverse Stereo Delay
This setting produces a more complicated effect by setting
the delay time separately on the left and right.

18
VOX DelayLab Owner’s manual
2. Vintage: Reverse Analog Delay
This setting applies modulation to the forward delay and
produces a feeling of floating. To obtain the modulation
effect, adjust the FWD/RVS balance and feedback.
3. Custom: Reverse Filter Delay
This setting is a reverse delay with a filter.
The center frequency of the filter moves synchronizing to
the delay time, which gives a unique sound.
Effect Type: LOOPER
With this effect you can apply a delay to a loop input.
1. Standard: Digital Delay
This setting is a delay that can set a delay time setting
separately for the left and right. You can easily produce
loops that have a stereo feeling.
2. Vintage: Analog Delay
With this setting you can combine the analog delay and
looper.
3. Custom: Space Delay
Depending on the parameter settings, you can produce
fantastic tracks when recording only a loop of various
string music and reverberant music. This looper decreases
the volume of the track already recorded and emphasizes
the new overdubbed sound each time overdubbing is
performed.
Restoring the factory settings
Here’s how to restore the DelayLab to its factory-set state.
This procedure will initialize the programs you’ve
saved, returning all of them to the factory-set programs.
1. Press and hold the CANCEL button and SYNC button
and connect a cable to the INPUT (L/MONO) jack.
