Effects

The Whammy DT is a powerful pitch shifting pedal offering both Drop and Raised re-tuning and classic Whammy pitch bending effects simultaneously. The left side controls Whammy, Harmony, and Detune effects, with the Expression Pedal controlling the pitch bend. The right side controls Drop Tuning (Shift Down) and Raised Tuning (Shift Up) options.

Whammy Effects

These effects bend your incoming signal up or down based on the selected setting. The Expression Pedal controls the bend from the original input pitch (toe up) to the selected effect pitch (toe down). These can be used with the Drop Tune effect.

• 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.

Diagram Description: A circular graphic shows various Whammy effect presets labeled with intervals like '2 OCT UP', '1 OCT UP', '5TH UP', '4TH UP', '2ND DN', '4TH DN', '5TH DN', '1 OCT DN', '2 OCT DN', and 'DIVE BOMB'.

Harmony Effects

These effects add a harmony to your incoming signal, mixing the harmony note with the input signal as if two guitars were playing. The harmony note bends between two intervals specified by the selected effect setting, while the input signal remains unchanged. This can be used with the Drop Tune effect.

• 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.

Diagram Description: A circular graphic shows various Harmony effect presets labeled with interval combinations like 'OCT DN/OCT UP', '5TH DN/4TH DN', '4TH DN/3RD DN', '5TH UP/7TH UP', '5TH UP/6TH UP', '4TH UP/5TH UP', '3RD UP/4TH UP', 'MIN 3RD UP/3RD UP', and '2ND UP/3RD UP'.

Detune Effects

These effects create a copy of your input signal, shift its pitch, and mix it back with the original signal. The Expression Pedal controls the amount of detuned signal. With the pedal in the toe-up position, only the dry signal is heard. As the pedal is rocked forward, the detuned signal is mixed in. This effect can be used with the Drop Tune effect.

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

Diagram Description: A circular graphic shows Detune effect presets labeled 'SHALLOW' and 'DEEP'.

Drop Tune Effects

These effects allow you to transpose (shift) your instrument up or down by a range of one octave for instant drop tuning or raised tuning simulation. The Octave + Dry effects create a 12-string guitar simulation. These effects can be used in combination with Whammy, Harmony, or Detune effects.

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.

Diagram Description: A graphic shows two rows of numbered buttons labeled 'SHIFT UP' (1-7, OCT, OCT DRY) and 'SHIFT DOWN' (1-7, OCT, OCT DRY).

Drop Tune Footswitches

Two footswitches are located below the Drop Tune effect section:

• DROP TUNE Footswitch: Turns the Drop Tune effect on and off, indicated by the LED above it.
• MOMENTARY Footswitch: Momentarily enables or bypasses the effect when pressed. This is designed for hammer-on and pull-off style effects with chords shifting from a transposed tuning to normal tuning.

Diagram Description: A view of the pedal's right side showing the 'DROP TUNE' and 'MOMENTARY' footswitches.

MIDI Functions

The Whammy DT features a MIDI input for receiving MIDI data. MIDI messages can select Whammy or Drop Tune effects and set their active or bypassed state. MIDI CC messages can control the Expression Pedal position.

MIDI Channel

The Whammy DT can receive MIDI messages on any channel. To change the MIDI channel:

1. Disconnect the power from the Whammy pedal.
2. Press and hold the WHAMMY Effect Footswitch while reconnecting power. A WHAMMY Effect LED will flash, indicating the current MIDI channel.
3. Rotate the WHAMMY Effect Knob to select the desired MIDI channel, using the reference chart.
4. Press the WHAMMY Effect Footswitch again to exit the MIDI setup menu.

Diagram Description: A chart shows MIDI channels (Chnl 1-16) corresponding to various Whammy and Harmony effect settings.

MIDI Program Changes

The Whammy DT uses MIDI Program Change commands for effect selection, allowing effects to be selected in either an active or bypassed state.

Whammy Effects MIDI Program Change Mapping:

This list outlines program change commands for Whammy effects and their status.

Drop Tune Effects MIDI Program Change Mapping:

This list outlines program change commands for Drop Tune effects and their state.

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.

Bypass Modes

There are two selectable Bypass Modes available in the Whammy DT:

• True Bypass
• DSP Bypass

True Bypass Mode

From the factory, the Whammy DT is set to True Bypass Mode. In this mode, the circuitry is completely bypassed when both Whammy and Drop Tune effects are off. To switch back to True Bypass Mode from DSP Bypass Mode:

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.

DSP Bypass Mode

The benefit of DSP bypass is that the Drop Tune Momentary footswitch can smoothly transition between momentary on and off states, as the true bypass relay is removed from the circuit. To enable DSP Bypass Mode:

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. The DROP TUNE Effect LED will light green when it is enabled while DSP bypass is active. DSP bypass remains active each time the Whammy DT is powered until True Bypass is enabled again.

Calibrating the Expression Pedal

If the expression pedal does not respond properly or the note does not bend/return to the correct pitch, it may need re-calibration. Follow these steps:

1. Disconnect the power from the Whammy pedal.
2. Press and hold the WHAMMY Effect Footswitch while reconnecting power. This enables MIDI and Calibration Setup. One of the WHAMMY Effect LEDs will flash, indicating the currently selected MIDI channel.
3. Rock the Expression Pedal fully forward (toe down) and then press the DROP TUNE Footswitch. The DROP TUNE Effect Status LED will first light red, then change to green, indicating Expression Pedal calibration is enabled. If the LED stays red, ensure the Expression Pedal is fully forward and press the DROP TUNE Footswitch until the LED turns 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 calibration.
5. When finished, press the WHAMMY Effect Footswitch again to exit the MIDI and Calibration setup and return to normal operation.

This completes the expression pedal calibration procedure.

FS3X Functions

The optional FS3X Footswitch provides hands-free control over selecting Whammy and Drop Tune effects.

1. Mode Switch: Selects which side (Whammy or Drop Tune) the FS3X Down/Up footswitches control. Pressing it once causes the currently selected effect on that side to flash 3 times, indicating the Down/Up footswitches will change the effect for that side.
2. Down Switch: Selects the next effect counter-clockwise in the Whammy or Drop Tune effect list.
3. Up Switch: Selects the next effect clockwise in the Whammy or Drop Tune effect list.

NOTE: The FS3X selects effects on either side regardless of whether the effect is on or off. Use only a 1/4" TRS cable for proper operation.

Diagram Description: A diagram shows the FS3X Footswitch with three buttons labeled 'MODE', 'DOWN', and 'UP'.
