V-Switch
The RP300A’s Expression Pedal includes DigiTech’s exclusive V-Switch. The V-Switch allows the
Expression Pedal assignment to be switched on the fly. Applying extra pressure to the toe of
the Expression Pedal will engage the V-Switch and the function of the Expression Pedal will
switch between the assigned parameter and Wah. The sensitivity or amount of pressure
required to engage the V-Switch can be adjusted to suit your personal taste (or weight of your
foot). See page 21 for the V-Switch Sensitivity adjustment procedure.
LFO
The RP300A includes two assignable low frequency oscillators (LFO TR and LFO SQ) which
can be assigned to any of the same parameters available for assignment to the Expression
Pedal. A low frequency oscillator will automatically vary the value of the assigned parameter at
a steady rate. A minimum and maximum value each LFO will reach may be also be assigned.
For instance; if the Amp Gain was assigned to LFO TR, and the minimum value was set at 1 and
the maximum value was set at 99, the RP300A would automatically sweep the amount of
distortion from a clean sound to a distorted sound. Individual LFO speeds are also available
for assignment. In the previous example, the LFO speed would determine the length of time it
took the LFO to sweep from the clean to the distorted sound. LFO TR oscillates using a
triangle waveform and LFO SQ uses a square waveform. The procedure for assigning the LFOs
in the RP300A is as follows:
1. Press the Select button until the Expression row has been selected (indicated by the LED
lighting on the Expression row).
2. Rotate the Number 1 Knob to select whether you want to assign LFO TR (LFO TR) or
LFO SQ (LFO SQ).
3. Rotate the Number 2 Knob until the desired Parameter appears in the Display. Your
choices include:
A GAIN (Amp Gain) - The LFO controls the Amp Gain or amount of distortion for the
selected Amp Type.
AMPLVL (Amp Level) - The LFO controls the Volume of the selected Amp Type.
