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.

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.
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.

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.
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.

*1 When SYNC is on, the TIME parameter operates as notes to the tap tempo.
*2 Specifies the combination of heads that will be used.
*3 When PITCH is 0 to 12, this adjusts the high attenuation. When PITCH is -12 to -0.1, this adjusts the low attenuation.
*4 Selects the rhythm pattern.
Rhythm pattern

*5 This sets the tone quality of the delay and models a clean digital when TONE is 10.0, high attenuation when TONE is 5.0 and an analog delay when TONE is 0.0.
