Operation
The ADG-1 is laid out in homage to modular synthesizers with three main
modules. They are the
DELAY
Module, the
LFO
(Low Frequency
Oscillator) and the
LEVEL
Module. Let us look closer at these modules.
DELAY MODULE
TIME:
The TIME knob adjusts the delay
time from 35mS to 700mS. If you change
the delay time while playing you will also
notice a pitch change as the signal currently
captured in the BBDs is spit out faster or
slower compressing or expanding the delay
time. This is how analog delays make that
great pitch-up or dive-bomb sound. Try
playing with a short delay with lots of
feedback then quickly turning the knob
clock-wise for massive dive bombs.
BUCKET SWITCH:
selects whether the sound you are hearing travels
through 1 or 2 BBDs (4096 or 8192 stages) and so halves or doubles the
delay time (17-350mS vs 35mS – 700mS). While there clearly is some
overlap in the settings, as you can often get the same delay time from either
setting, the tone is slightly different in each, so you may prefer one position
over the other. In general, use the down position for long reverberant
delays. Use the up position for more sparkly shimmering delays, or when
doing chorus or flange-like sounds.
FEEDBACK:
The FEEDBACK knob affects how much post TONE
delayed signal is fed back into the buckets. This affects the number of
repeats and fade-out time. Past around 3:00 it puts the ADG-1 into self-
oscillation for some wild swishing sounds that change as you move the
TIME knob. Try it out, get lost. Come back after and read the next section.
Be sure to read the control voltage section for information on this module
with expression pedals or control voltages.
