1. Expression Pedal
This pedal is used to control the pitch bending amount of the selected Harmony,
Whammy, or Detune eect. Rocking it forward (toe down) increases the amount of pitch
bending while rocking it back (toe up) decreases the amount of pitch bending.
2. Harmony LEDs
One of these LEDs will light when a Harmony eect is selected. Harmony eects have dry
signal added to the eect signal.
3. Classic/Chords Switch
This switch toggles between the classic Whammy algorithm (Classic) and modern chordal
algorithm (Chords). The Classic setting is ideal for single note play while the Chords
setting is best suited for bending of full chords.
4. Selector Knob
This knob is used to select one of the Whammy, Harmony, or Detune eects.
5. Whammy LEDs
One of these LEDs will light when a Whammy eect is selected. Whammy eects do not
have dry signal added to the eect signal.
6. Detune LEDs
One of these LEDs will light when a Detune eect is selected. The Expression Pedal
controls the amount of Detune signal mixed with the dry signal.

7. Status LED
This LED lights to indicate the eect is on. When the eect is bypassed, this LED will be
o.
8. Eect On/O Footswitch
This switch turns the Whammy, Harmony, or Detune eect on and o.
9. Power Input
Connect the power supply to this jack. Do not use any power supply other than the
included power supply.
10. Output Jack
Connect this jack to another pedal input or the input of an amplier.
11. Instrument Input
Connect your instrument to this jack.
12. MIDI Input
Connect an external MIDI device to this jack for the purpose of controlling the Bass
Whammy remotely.

Making Connections
The Bass Whammy pedal is extremely easy to set up and use. Follow these steps to get up and
running.
1. Connect your instrument to the Bass Whammy’s
Input
Jack .
2. Connect from the Bass Whammy’s Output Jack to your favorite distortion pedal or to
your amplier.
3. If using an external MIDI device for control, connect from the MIDI out of the MIDI
device to the Bass Whammy’s
MIDI Input.
4. Connect the included power supply to an AC outlet and the other end to the Bass
Whammy’s Power Input.
5. Turn on your amp and adjust the volume to the desired level.
6. Use the Eect On/O Footswitch to enable the eect, rotate the Selector Knob to
select the desired eect, and rock the Expression pedal.

Eects
Whammy Eects
This group of eects will bend your incoming signal either up or down depending upon the eect
setting you have chosen. As the Expression Pedal is rocked back and forth, the signal will bend
from the original input pitch (toe up), to the pitch specied by the selected eect setting (toe
down).

2 OCT UP – Bends your input note two octaves up.
1 OCT UP – Bends your input note one octave up.
5TH UP – Bends the input note 7 semitones (5th interval) up.
4TH UP – Bends the input note 5 semitones (4th interval) up.
2ND UP – Bends the input note 2 semitones (2nd interval) up
2ND DN – Bends the input note 2 semitones (2nd interval) down.
4TH DN – Bends the input note 5 semitones (4th interval) down.
5TH DN – Bends the input note 7 semitones (5th interval) down.
1 OCT DN – Bends your input note one octave down.
DIVE BOMB – Bends your input note three octaves down.

Harmony Eects
This group of eects add a harmony to your incoming signal. Both the harmony note and the input
signal are mixed together as if two basses were playing simultaneously. As you rock the pedal back
and forth, the harmony note bends between two intervals specied by the selected eect setting,
but the input signal remains unchanged.
OCT UP/2 OCT UP– Bends the harmony between one octave above (toe up)
and 2 octaves above (toe down) the input note.
OCT UP/10TH UP – Bends the harmony between an octave above (toe up)
and a 10th above (toe down) below the input note.
OCT DN/OCT UP –Bends the harmony between an octave below (toe up)
and a octave above (toe down) the input note.
OCT DN/4TH DN –Bends the harmony between an octave below (toe up)
and a fourth below (toe down) the input note.
5TH UP/OCT UP –Bends the harmony between a fth above (toe up) and
an octave above (toe down) the input note.
5TH UP/6TH UP –Bends the harmony between a fth above (toe up) and
an sixth above (toe down) the input note.
5TH DN/5TH UP –Bends the harmony between a fth below (toe up) and a
fth above (toe down) the input note.
4TH DN/5TH UP –Bends the harmony between a fourth below (toe up)
and a 5th above (toe down) the input note.
4TH DN/3RD UP –Bends the harmony between a fourth below (toe up)
and a major third above (toe down) the input note.

Detune Eects
This group of eects create a copy of your input signal, shift the pitch of the copied signal, then
mix it back with the original signal. As the Expression Pedal is rocked back and forth, the level of
this detuned signal is changed. With the pedal in the toe up position, only the original dry signal
is heard. As the pedal is rocked forward, more of the detuned signal is mixed with the dry signal.

SHALLOW – The copied signal is slightly detuned from the original pitch.
DEEP – The copied signal is substantially detuned from the original pitch.

MIDI Functions
The Bass Whammy features a MIDI input for receiving incoming MIDI data. MIDI messages can
select a Whammy eect and set whether the eect is in an active or bypassed state. MIDI CC
messages can then be used to control the Bass Whammy Expression Pedal position.
MIDI Channel
The Bass Whammy can receive MIDI messages on any, or all MIDI channels. The following steps
outline the procedure for accessing or changing the MIDI channel.
1. Disconnect the power from the Bass Whammy pedal.
2. Press and hold the
Eect On/O Footswitch while reconnecting the power. One of the
Eect LEDs will begin to ash indicating the currently selected MIDI channel.
3. Using the reference chart below, rotate the Selector Knob to select the desired MIDI
channel.
4. Press the
Eect On/O Footswitch again to exit the MIDI set up menu.

MIDI Program Changes
The Bass Whammy uses MIDI Program Change commands for eect selection. Eects can be
selected in either an active or bypassed state. The following illustrations show the MIDI Program
Change mappings for Classic mode and Chords mode.

MIDI Continuous Control
Using MIDI continuous control commands, the Bass Whammy’s Expression Pedal position can be
remotely controlled. MIDI CC11 adjusts the Expression Pedal position. A value of 0 on MIDI CC11
corresponds to a toe up position and a value of 127 corresponds to a toe down position.

Calibrating the Expression Pedal
In the unlikely event that the Expression Pedal does not respond properly or that the note does
not bend or return to the correct pitch, it may need to be re-calibrated. The following steps outline
the procedure for Expression Pedal re-calibration:
1. Disconnect the power from the Bass Whammy pedal.
2. Press and hold the
Eect On/O Footswitch while reconnecting the power. This
enables MIDI and Calibration Setup. Wait for one of the Whammy, Detune, or
Harmony LEDs to begin ashing (indicating the currently selected MIDI channel) then
release the footswitch.
3. Rock the
Expression Pedal fully forward (toe down) and fully back (toe up) at least two
times. The 4 Harmony LEDs will light back and forth (from OCT DN/4TH DN to OCT
UP/2 OCT UP) as the pedal is rocked indicating the pedal is calibrating.
4. When nished, press the
Eect On/O Footswitch again to exit the MIDI and
Calibration set up and return to normal operation.
