DOD Rubberneck Analog Delay Pedal

Introduction

Thank you for choosing the DOD Rubberneck Analog Delay pedal. The Rubberneck is an extended-feature delay pedal that uses BBDs for classic analog delay up to 1.5 seconds. The Rubberneck functions as a standard delay pedal but also includes several performance features not found in other analog delay pedals. These include 'Rubbernecking,' a function that allows delay repeats to be stretched or compressed in time; repeats oscillation, a function that provides a secondary delay feedback setting to create momentary oscillation effects; and a Loop Send/Return jack for adding effects to the delay signal's feedback path. The FOOTSWITCH input jack allows for connecting a DigiTech FS3X footswitch for hands-free control of Rubbernecking, modulation on/off, and Tap Tempo/Regen. The Rubberneck Analog Delay pedal is everything you need to achieve that truly classic analog delay sound, with modern feature enhancements to transport your delay effects into the future.

Features

• Up to 1.5 seconds of delay time
• Unique Rubberneck time-stretching function
• Controls for Time, Repeats, Level, Modulation Speed, Modulation Depth, Gain, Tone, Rubberneck Speed, and Regen Adjust
• Tap Ratio toggle switch to select delay feel
• Tails Switch
• Effect On/Off footswitch (also activates Rubbernecking function)
• Tempo/Regen footswitch for tap tempo and momentary delay feedback changes
• 1/4" mono input and output jacks
• Footswitch input jack for additional hands-free control
• Loop Send/Return jack for adding effects to the delay feedback path
• True Bypass
• 9 VDC operation (optional power supply required)

Quick Start

1. Engage the effect with the EFFECT ON footswitch (the LED to the right of the footswitch illuminates solid green when the effect is active).
2. Use the TIME, REPEATS, and LEVEL knobs to set the delay interval, number of repeats, and delay output level. Use the TAP RATIO switch to set the delay 'feel'.
3. Use the RATE and DEPTH modulation knobs to subtly vary the delay time. This provides a slight chorus effect on the delay repeats.
4. Use the GAIN knob to control the amount of distortion added to the delay signal. Use the TONE knob to alter the tone of the delay signal.
5. Set the TAILS switch to the desired position:
   • On+NoDry – The dry signal is cut when the effect is engaged. Note that the signal will pass through a buffered signal path when the effect is bypassed, rather than being true bypass. Delay repeats will still sound after the effect is bypassed.
   • On – Delay repeats will continue to sound after the effect is bypassed. Note that the signal will pass through a buffered signal path when the effect is bypassed, rather than being true bypass.
   • Off – Delay repeats are cut immediately when the effect is bypassed. Use this setting if you want true bypass.
   Use these additional features to take your delay effects to the next level:
   • Tap Tempo: Tap the TEMPO/REGEN footswitch to set the delay time hands-free. Each tap interval will change the delay (indicated by the LED to the left of the footswitch) to match the tapped intervals. Used in conjunction with the TAP RATIO switch, you can achieve triplet or double-time delays depending on the tap interval.
   • Rubbernecking: Press and hold the EFFECT ON footswitch to engage 'Rubbernecking,' a function where the delay time is stretched or compressed over time. This can create 'dive bomb' or 'chipmunk' type delay hits during a performance. Use the RUBBERNECK RATE control to set the attack/release of the delay stretch.
   • Repeats Oscillation: Press and hold the TEMPO/REGEN footswitch to momentarily engage the REGEN ADJUST control. This is essentially a secondary feedback control that replaces the REPEATS knob setting with the REGEN ADJUST potentiometer setting whenever the TEMPO/REGEN footswitch is pressed and held. By setting different REPEATS and REGEN ADJUST parameters, you can transition from single repeats to runaway oscillations and back by holding and releasing the TEMPO/REGEN footswitch.
   • Loop Send/Return: The Loop Send/Return jack allows you to insert other effects (e.g., distortion, ring modulator, phaser, flanger) into the delay signal's feedback path. This allows you to create wild delay effects that can dynamically change their sound with each repeat.

User Interface

Top Panel

• 1. EFFECT ON / RUBBERNECK Footswitch: Engages or disengages the delay effect. When this footswitch is pressed and held, the 'Rubberneck' delay time-stretching function is active until the footswitch is released.
• 2. RUBBERNECK RATE Potentiometer and LED: The Rubbernecking function creates a stretched, 'elastic' sounding audio effect when the EFFECT ON footswitch is held down. This is accomplished by shortening or lengthening the delay time at a variable rate. The setting of the RUBBERNECK RATE potentiometer will increase or decrease the time it takes to reach the full range of the stretched sound. The first half (left) of the control sets the delay time stretch (divebomb) and the second half (right) of the control sets the delay time compression rate. The RUBBERNECK RATE potentiometer is a transparent backlit potentiometer with a bi-color LED below it that serves a dual function: LED Off: The delay effect is bypassed. LED On: The LED illuminates solid green when the effect is engaged. The LED blinks between green and yellow to indicate the modulation speed set by the RATE knob. The faster the modulation speed, the faster it blinks between green and yellow. If the DEPTH knob is set to minimum, the LED remains solid green to indicate no modulation is active. When the Rubbernecking function is active, the LED illuminates solid red.
• 3. TAP RATIO Switch: Selects the ratio between tapped tempos and the delay time produced. There are three settings:
  • Quarter Note: The tap interval selects the delay time in a 1:1 ratio.
  • Dotted Eighth Note: Provides a triplet feel when quarter notes are played.
  • Eighth Note: The delay time is halved based on the tap interval.
• 4. TIME Knob: Controls the delay time. It is variable from 30 ms to 1.0 second. With the Tap Tempo function, the delay time can be extended up to 1.5 seconds.
• 5. RATE / DEPTH Knobs: These concentric knobs are used to control the modulation speed (Rate) and depth of the delay signal. Using modulation creates a chorus effect on the repeats. Turning these knobs clockwise increases speed and intensity, and turning the knobs counter-clockwise decreases speed and intensity. Turning the DEPTH knob to the minimum position will disable the modulation effect.
• 6. REPEATS Knob: Controls the number of delay repeats heard. When used in conjunction with the GAIN and TONE controls, the repeats can run away into oscillation at higher settings, for truly wild effects.
• 7. GAIN / TONE Knobs: The GAIN knob is used to increase the gain of the signal sent into the delay, making the repeats more or less distorted. The TONE knob is used to make the delay signal brighter or darker.
• 8. LEVEL Knob: Controls the level of the delay signal sent to the output.
• 9. TAILS Switch: Determines whether delay repeats will continue to be heard after the effect is bypassed, or if the dry signal will be heard. Three settings are available:
  • On+No Dry – The dry signal path will be cut when the effect is engaged. Note that the signal will pass through a buffered signal path when the effect is bypassed, rather than being true bypass. Delay repeats will still be heard after the effect is bypassed.
  • On – Delay repeats will continue to be heard when the effect is bypassed. Note that the signal will pass through a buffered signal path when the effect is bypassed, rather than being true bypass.
  • Off – Delay repeats are cut immediately when the effect is bypassed. Use this setting if you want true bypass.
• 10. REGEN ADJUST Potentiometer and LED: This miniature potentiometer functions as a secondary REPEATS setting and becomes active when the TEMPO / REGEN footswitch is pressed and held. Setting this potentiometer to a high setting with a high TONE and GAIN setting will cause the delay effect to run into uncontrollable oscillation for as long as the TEMPO / REGEN footswitch is held down. The REGEN ADJUST potentiometer is a transparent backlit potentiometer with a white LED below it. The LED under the potentiometer will blink at the delay time set by the TIME knob or by tapping tempo using the TEMPO / REGEN footswitch. The LED will blink even when the effect is bypassed, allowing you to tap in a tempo before engaging the delay. The LED will illuminate solid when the TEMPO / REGEN footswitch is pressed and held to activate the secondary REPEATS state.
• 11. TEMPO / REGEN Footswitch: Tap this footswitch to tap in the delay time. The time is set based on the interval between taps in conjunction with the position of the TAP RATIO switch. Tap tempo can be performed with the effect engaged or bypassed. Press and hold this footswitch to engage the REGEN function, switching the REGEN ADJUST potentiometer into the audio path and the REPEATS potentiometer out of the audio path to create a momentary secondary delay regeneration setting using the REGEN ADJUST potentiometer. Release the TEMPO / REGEN footswitch to return to normal operation, with the REPEATS potentiometer back in the audio path.

• 1. Input Jack: Connect your guitar or the output of another pedal to this jack.
• 2. Send/Return Jack: This TRS jack provides a send/return loop path for inserting effects into the delay circuit's feedback path. The tip is the send and the ring is the return. The Loop Send/Return jack operates at instrument level, so it is designed to be used with most effect pedals.
• 3. Output Jack: Connect this output to the input of your guitar amplifier or the next effect in line.
• 4. Footswitch Jack: Connect an optional DigiTech FS3X footswitch to this jack to remotely control functions such as Rubbernecking, Modulation on/off, and Tap Tempo/Regen. See 'Using an External Footswitch' on page 9 for more information.
• 5. Power Jack: Connect a 9VDC PS0913DC adapter or equivalent to this jack. The Rubberneck does not operate on batteries and requires a power adapter to function.

Connections and Setup

Connection Diagrams

A typical connection involves plugging your guitar into the INPUT jack. The OUTPUT jack connects to your amplifier's input. For using the effects loop, connect the SEND/RETURN jack's TIP (Send) to the input of an external effect and the RING (Return) from the output of that external effect. An optional DigiTech FS3X footswitch can be connected to the FOOTSWHITCH jack for remote control of functions like Rubbernecking, Modulation, and Tap Tempo/Regen. The unit requires a 9VDC power supply connected to the POWER jack.

NOTE: If your amp's effects loop has a mix control, set the mix to 100% wet.

Powering Up

1. Turn down your amplifier's master volume.
2. Make all connections to the Rubberneck as shown in the 'Connection Diagrams'.
3. Connect the appropriate power supply (sold separately) to the POWER input jack and plug the other end into an available AC outlet.
4. Strum your guitar and gradually increase your amplifier's master volume until the desired level is reached.

Using an External Footswitch

The FOOTSWICH input jack accommodates an optional DigiTech FS3X footswitch for remote control of Rubbernecking, Modulation on/off, and Tap Tempo/Regen functions. Other third-party momentary footswitches may also be used, but may not offer full functionality.

NOTE: For full functionality, connect the DigiTech FS3X footswitch using a TRS cable. A TS cable can be used to control Tap Tempo and Regen when using a third-party momentary footswitch (latching footswitches will not work). When using a third-party momentary footswitch with a TS cable, it must first be connected to the Rubberneck before powering on to allow the Rubberneck to detect it and function properly.
