Effects
The Whammy DT is a powerful pitch shifting pedal that offers both Drop and Raised re-tuning
of your instrument and classic Whammy pitch bending effects simultaneously. The left side of the
pedal allows you to select from one of the traditional Whammy effects: Whammy, Harmony and
Detune; the Expression Pedal will then control the bend of the selected Whammy effect. The
right side of the pedal interface controls the Drop Tuning (Shift Down) and Raised Tuning (Shift
Up) options.
Whammy Effects
This group of effects will bend your incoming signal either up or down depending upon the effect
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 specified by the selected effect setting (toe
down). This effect can be used in combination with the Drop Tune effect. Whammy effects include:
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 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.
2 OCT DN – Bends your input note two octaves down.
DIVE BOMB – Bends your input note three octaves down.

Page 6
Harmony Effects
This group of effects add a harmony to your incoming signal. Both the harmony note and the input
signal are mixed together as if two guitars were playing simultaneously. As you rock the pedal back
and forth, the harmony note bends between two intervals specified by the selected effect setting,
but the input signal remains unchanged. This effect can be used in combination with the Drop Tune
effect. Harmony effects include:
OCT DN/OCT UP – Bends the harmony between one octave below (toe up) and
one octave above (toe down) the input note.
5TH DN/4TH DN – Bends the harmony between a fifth (toe up) and a fourth (toe
down) below the input note.
4TH DN/3RD DN – Bends the harmony between a fourth (toe up) and a minor
third (toe down) below the input note.
5TH UP/7TH UP – Bends the harmony between a fifth (toe up) and a dominant
seventh (toe down) above the input note.
5TH UP/6TH UP – Bends the harmony between a fifth (toe up) and a sixth (toe
down) above the input note.
4TH UP/5TH UP – Bends the harmony between a fourth (toe up) and a fifth (toe
down) above the input note.
3RD UP/4TH UP – Bends the harmony between a third (toe up) and a fourth (toe
down) above the input note.
MIN 3RD UP/3RD UP – Bends the harmony between a minor third (toe up) and a
major third (toe down) above the input note.
2ND UP/3RD UP – Bends the harmony between a second (toe up) and a third (toe
down) above the input note.

Page 7
Detune Effects
This group of effects creates a copy of your input signal, shifts the pitch of the copied signal and
mixes it back with the original signal. As the Expression Pedal is rocked back and forth, the amount
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, the detuned signal is mixed with the dry signal. This effect
can be used in combination with the Drop Tune effect. The Detune effects include:
SHALLOW – The copied signal is slightly detuned from the original pitch.
DEEP – The copied signal is substantially detuned from the original pitch.

Page 8
Drop Tune Effects
This group of effects allow you to transpose (shift) your instrument up or down – with a range
of one octave in each direction – for instant drop tuning or raised tuning simulation. The Octave
+ Dry effects create a 12 string guitar simulation. This effect can be used in combination with the
Whammy, Harmony or Detune effect. Drop Tune effects include:
SHIFT UP
OCT + DRY – Transposes guitar signal up 1 octave and adds dry signal.
OCT – Transposes guitar signal up 1 octave.
7 – Transposes guitar signal up 7 semitones.
6 – Transposes guitar signal up 6 semitones.
5 – Transposes guitar signal up 5 semitones.
4 – Transposes guitar signal up 4 semitones.
3 – Transposes guitar signal up 3 semitones.
2 – Transposes guitar signal up 2 semitones.
1 – Transposes guitar signal up 1 semitone.
SHIFT DOWN
1 – Transposes guitar signal down 1 semitone.
2 – Transposes guitar signal down 2 semitones.
3 – Transposes guitar signal down 3 semitones.
4 – Transposes guitar signal down 4 semitones.
5 – Transposes guitar signal down 5 semitones.
6 – Transposes guitar signal down 6 semitones.
7 – Transposes guitar signal down 7 semitones.
OCT – Transposes guitar signal down 1 octave.
OCT + DRY – Transposes guitar signal down 1 octave and adds dry signal.

Drop Tune Footswitches
There are two footswitches below the Drop Tune effect section. The DROP TUNE footswitch is
used to turn the Drop Tune effect on and off as indicated by the LED above this footswitch. The
MOMENTARY footswitch is used to momentarily enable or bypass the effect when pressed. This
is designed to create hammer-on and pull-off style effects with chords shifting from a transposed
tuning to normal tuning.

Page 10
MIDI Functions
The Whammy DT features a MIDI input for receiving incoming MIDI data. MIDI messages can
select a Whammy or Drop Tune effect and set whether these effects are in an active or bypassed
state. MIDI CC messages can then be used to control the Whammy Expression Pedal position.
MIDI Channel
The Whammy DT 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 Whammy pedal.
2. Press and hold the WHAMMY Effect Footswitch while reconnecting the power. One
of the WHAMMY Effect LEDs will begin to flash indicating the currently selected MIDI
channel.
3. Using the reference chart below, rotate the WHAMMY Effect Knob to select the desired
MIDI channel.
4. Press the WHAMMY Effect Footswitch again to exit the MIDI set up menu.

Page 11
MIDI Program Changes
The Whammy DT uses MIDI Program Change commands for effect selection. Effects can be
selected in either an active or bypassed state.
Whammy Effects MIDI Program Change Mapping
The following list outlines the program change commands recognized by the Whammy DT and the
corresponding Whammy effect setting and its status.

Page 12
Drop Tune Effects MIDI Program Change Mapping
The following list outlines the program change commands recognized by the Whammy DT and the
corresponding Drop Tune effect and state.

Page 13
MIDI Continuous Control
Using MIDI continuous control commands the 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.

Page 14
Bypass Modes
There are two selectable Bypass Modes available in the Whammy DT, they are:
•True Bypass
•DSP Bypass
True Bypass Mode
From the factory, the Whammy DT is set to True Bypass Mode. In this mode, the circuitry in the
Whammy DT is completely bypassed when both Whammy and Drop Tune effects are off. If you
have switched to DSP Bypass Mode and would like to switch back to True Bypass Mode, follow
these steps:
1. Start with the power supply disconnected from the Whammy DT.
2. Press and hold the MOMENTARY Footswitch and apply power.
3. When the DROP TUNE Effect LED flashes red two times, release the MOMENTARY
Footswitch.
True bypass will now be re-enabled.

Page 15
DSP Bypass Mode
The benefit of using DSP bypass is so the Drop Tune Momentary footswitch can smoothly transition
between momentary on and off states since the true bypass relay is removed from the circuit.
To enable DSP Bypass Mode, follow these steps:
1. Start with the power supply disconnected from the Whammy DT.
2. Press and hold the MOMENTARY Footswitch and apply power.
3. When the DROP TUNE Effect LED flashes green two times, release the MOMENTARY
Footswitch.
DSP bypass is now enabled on the Whammy DT. The DROP TUNE Effect LED will now light green
when it is enabled while DSP bypass is active. DSP bypass will remain active each time the Whammy
DT is powered until True Bypass is enabled again.

Page 16
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 Whammy pedal.
2. Press and hold the WHAMMY Effect Footswitch while reconnecting the power. This
enables MIDI and Calibration Setup. One of the WHAMMY Effect LEDs will begin to flash
indicating the currently selected MIDI channel.
3. Rock the Expression Pedal fully forward (toe down) and then press the DROP TUNE
Footswitch. When you press the footswitch, the DROP TUNE Effect Status LED will first
light Red and then change to Green indicating Expression Pedal calibration is now enabled.
If the DROP TUNE Effect Status LED stays Red, make sure the Expression Pedal is
rocked fully forward and press the DROP TUNE Footswitch until the LED lights Green.
4. Rock the Expression Pedal fully back (toe up) and fully forward (toe down) at least two
times. The SHIFT UP LEDs will light back and forth (from 1 to OCT + DRY) as the pedal
is rocked indicating the pedal is calibrating.
5. When finished, press the WHAMMY Effect Footswitch again to exit the MIDI and
Calibration set up and return to normal operation.
This completes the expression pedal calibration procedure.
