AMP MODULE
The
AMP
modules provide wet and dry signal blending as well as tonal
control of the ACV-1 wet signal.
MIX:
The MIX knob provides a
cross-faded wet/dry mix between the
delayed wet and clean tone. A 1:1
mix, providing the deepest comb
notches, is at about 11:00 and not
12:00. It may be easier to find this
with shorter delay times. When
turned fully CW the ACV-1 will produce vibrato effects similar to a
rotating speaker.
Note: If you are applying a sustained steady pitch to the ACV-1 and have the
MIX
knob
set near 12:00, you may find that the direct and delayed signals alternately will reinforce
or cancel each other as the
DELAY TIME
is varied. This is a normal result of mixing a
steady pitch with a delayed replica of itself. This phase cancelation is the chorus/delay
equivalent of “standing waves” in a reverberant room.
TONE:
The TONE knob is a continuation of
Hawker
’s highly acclaimed
ADG-1 tone control that has been re-voiced slightly higher for the ACV-1.
It is a modified, non-symmetrical, “tilt type” filter with a soft curve and
center flat position. It provides both high pass and low pass control with a
knee around 740Hz. It is placed after the bucket and INSIDE the feedback
loop and will bring out or dampen the delayed mix allowing it to become
more present or fit under your playing. Extreme settings of this will
accentuate the feedback amount and cause self-oscillation.
