The online manual for the Digitech 2101 guitar multieffects processor is well
worth reading, for its explanations of the many parameters controllable in the
2101 guitar multiprocessor.
2101 Effects (expired?)
I assume the 2120 manual describes all the effects. To get the 2120 manual
from the Digitech site, see my page DigiTech 2120 (2101,
2112) preamp/fx-processor with speaker simulator, $1150.
Delay Parameters are as follows:
Effect On / Off: Turns the Module on or off.
When the Module is turned off, its
Parameters are not displayed, and signal will
not continue to pass through the module. To
see the Parameters, you must turn the
Delay Time (Tap #): Controls the delay time
of the tap indicated in the display. If no tap
number is shown, this Parameter controls the
overall delay time of the Module. DELAY
TIMEs are editable in two different ranges to
give the most flexibility and accuracy in the
least amount of scrolling time. If you turn the
Data wheel when the cursor is in the hundred
milliseconds position (one place to the right of
the decimal), you will increase or decrease
the delay time in increments of 100
milliseconds. Pressing the Parameter's
Function key moves the cursor to the third
position to the right of the decimal point, or
milliseconds position. Each click of the Data
wheel from this position increases the delay
time in single millisecond steps. Using this
method of ranging allows you to scroll rapidly
to large-value delay times without having to
wait for the unit to scroll to it in single
millisecond steps. Variable from 0.000 sec.
to 5.000 sec.
Feedback (Tap #): Controls the amount of
feedback, or number of repeats, in the delay
line. In multi-tap delays, this Parameter
controls the feedback amount of the last tap
in the series. Variable from 0 (Off) to 100%.
(see fig. 3-9)
LFO Speed: Controls the speed of the
modulation sweep. Variable from .06 Hz to
16.00 Hz. This Parameter appears only in
LFO Depth: Sets the sweep depth (intensity)
of the delay modulation. Variable from 0.00
to 40.00 milliseconds. This Parameter
appears only in Modulated Delays.
LFO Waveform Type: Controls the LFO
(low-frequency oscillator) waveform pattern
of the delay modulation effect. SINE
produces a smooth sine wave-type
modulation with even transitions in and out of
turnaround points. TRIANGLE is a linear
modulation effect, and ramps the pitch of the
wave up and down with no slowing at
turnaround points. LOGARITHMIC and
EXPONENTIAL waveforms are more
dramatic in their effect on the signal,
producing a type of bouncy oscillation. This
Parameter appears only in Modulated
Level: Controls the level of the delay
Module. Variable from 1 to 100.
Repeat Hold: This is the infinite repeat
Parameter. When turned on, the delay taps
will repeat indefinitely until the Repeat Hold
Parameter is disengaged. (see fig. 3-10)
