Bass wah, Model pba – Morley BASS WAH (PBA) User Manual
Page 2

Here is a general recommendation for hooking up a WAH
with other effects:
NOTE: This pedal is not intended for use through an effects
loop (send and return).
FEATURES
•
Electro-Optical: The amount of light from the
LED (Light Emitting Diode) that shines on the
LDR (Light Dependent Resistor) is controlled by a
shutter placed between the two devices. Our unique
electro-optical design ensures smooth overall
control of the WAH without unwanted noise typical
with potentiometer (pot) controlled pedals.
•
Electro-Optical Switching: Your pedal features
electro-optical switching circuitry that allows the
PBA to go into WAH mode without actuating a
switch
•
Silent Switching: To further enhance the noiseless
operation of our electro-optical design, we’ve added
FET silent switching. Standard switching methods
will “pop” and “click” when switching from WAH
to bypass. Your PBA offers a smooth and quiet
transition, making this pedal ideal for studio
recording as well as live performance.
