11. –15 dB PAD JUMPER: Moving the
jumper reduces the input signal by 15
dB and compensates for higher output
instruments. This attenuation is suited
for use with basses that have active
electronics or high-output pickups.
There are only two possibilities for the
jumper setting:
• Pins 1-2 (Normal – default)
• Pins 2-3 (15 dB Pad)
Ok, ok...there could be no jumper, but
that just sets the pedal to its normal/
default, Pins 1-2 setting (with about
1/2 dB loss).
Referencing the diagram to the left,
slide the jumper out then back in on
the pins that you want to use for your
instrument. Fingers should work just
ne, but it’s ok to use needle-nose
pliers to remove the jumper, if
necessary.
NOTE: When replacing the bottom of
the pedal, line up the rectangular foam
piece over the battery. Turn the screws
clockwise to ax to the bottom to the
pedal.
NOTE: If you are experiencing
excessive distortion (distortion begins
at approximately 1.5V RMS) then you
might want to utilize the -15 dB Pad
by moving the jumper to Pins 2-3.
