The Digital Delay DGD-2 is a 24-bit audio resolution
Delay, giving musicians more versatility in the studio
and better performance for live applications by using
the TAP TEMPO capacity.

AC adaptor jack: AC adaptor Jack: Accepts connection
of an external AC adaptor. By using an AC adaptor you can
play without being concerned about the battery life.
Input Jack: Connect your instrument cord or the output
of another effect pedal if you are linking pedals together.
Output Jacks A and B: These output jacks will
deliver the effected sound to your amplifiers or to an
input jack of another effect.
When using a single amplifier use output jack A. If you
wish to use two amplifiers, connect the first unit into
output A and the second unit into output B.
By using two amplifiers you will obtain a great surround
effect in your sound.
Pedal: Depress to turn on/off the pedal.
Depress and hold it for about 2 seconds to turn on/off in
the TAP TEMPO mode. For more instructions about how
to use the TAP TEMPO mode please refer to page 7.
Thumbscrew: By loosing this thumbscrew you will gain
access to the battery compartment. For instructions on
how to replace the battery please refer to page 4.
Effect Level Knob: Gives you control of the level of
output effect. Use this knob to blend how much delay
you want in your sound.
Get more delay by turning this knob to the right, and
less by turning it to the left.
Feedback Knob: Use this knob to control how much
feedback you wish to add in your delay sound.
By turning it totally to the left, you will get a single delay.
By turning it to the right, you will get countless delay.

Delay Time Knob: Gives you control of Delay Time in
milliseconds.
The minimum delay time of this unit is 10 milliseconds
and the maximum is 1250 milliseconds.
Mode Switch: Switches the operation mode (Hold
and Delay).
Hold: In this position the indicator led will light in orange.
Step and hold for recording up to 1250 milliseconds.
When released you may play together with the recorded
riff.
While in HOLD position the DGD-2 cannot be turned off
by using the foot pedal, as it is required to determinate
how long you are sampling.
The other controls will also be disabled when switched
to HOLD position.
Delay: In this position the indicator led will light in red
after depressing the pedal. This indicates that the DGD-2
is now working in delay mode and all knob controls are
enabled.
Selection & Check: This led indicates the pedal
status, having three distinct colors:
Orange: When DGD-2 is working in HOLD mode.
Red: When DGD-2 is working in DELAY mode and the
TAP TEMPO function is disabled.
Green: When DGD-2 is working in DELAY mode and
the TAP TEMPO function is enabled.

The RTTP function is a great ally for the musician as it
allows fast and accurate adjustments of DELAY TIME in
real time.
To enable the RTTP function in your DGD-2 the mode
switch must be switched to DELAY position. After that,
please refer to the instructions below.
Depress and hold the pedal switch for about 2 seconds.
If the indicator led of your DGD-2 is turned off, it will
turn on in green. If the DGD-2 is already turned on in
DELAY mode the indicator led will change its color to
green. This indicates that now you are using the DGD-2
under TAP TEMPO function.
The RTTP mode gives you the ability to change the
Delay Time by using your foot. Your hands will be free
to play without being concerned about the DELAY TIME
knob.
Now it is quite simple! While working in RTTP mode, to
increase or decrease the DELAY TIME, you just need to
depress the pedal three times in the same speed that
you would wish to set up the new Delay Time. The internal
DGD-2 circuitry can read the speed you stomped in real
time and will assume this speed as the new Delay Time
set.
If you wish to change it again, just depress three times
in the new speed you desire. You can change any time
you want while working in RTTP mode. To turn the effect
off simply depress and hold it for 2 seconds. This will
switch the DGD-2 to bypass mode.
