INTRODUCTION
Congratulations, and thank you for your purchase of the DOD Tec4X Multi-Effects Processor. The Tec4X
is newly re-designed for great tone, effects, and flexibility. With the Tec4X you get 15 separate effects,
including DOD’s world famous GRUNGE™ distortion. You also get lush chorusing, rich delays, reverbs,
and special FX not found anywhere else. DOD’s Pixellator™ and Enveloped FX allow you to break new
sonic ground. We also provide a 3-band EQ for total tone control of each preset. With 30 new factory
presets, and space for 30 more of your own concoctions, the Tec4X gives you the tools to find your own
sound. With a feature menu that reads like this, one would expect to pay a great deal more for a multieffects processor of this caliber, but not at DOD. We always provide more for less.
FUNCTIONS
1. Program and Bank Selector Foot switches: These foot switches provide access to the TEC4’s banks/programs.
2. Power Adapter Input: This is where the PS200R power supply is connected. Use only the DOD PS200R, other
adapters may damage the TEC4, and void the warranty.
3. Volume/Wah/Sensitivity Control Input: Connect optional DOD VCC1 to have real time control over volume
levels, wah ranges, and auto wah sensitivity.
4. Effect Selector Buttons: These buttons allow you to select the effects you wish to use or bypass.
5. LED Display: The LED display in program mode shows which bank and program is currently selected. In Edit
mode it shows the number and/or status of the selected effect. In Tuner mode it displays the note currently being
played.
6. Store and User LEDs: The Store LED indicates that a change has been made to a preset. The User LED indicates
whether you are in user, or factory banks.
7. Store Button: Use this button to store your custom programs in the user memory location of choice.
8. Up/Down Buttons: These buttons scroll up/down selected effects (edit mode), or up/down through
banks/presets (performance mode).
9. Output Knob: Controls the overall output level sent to your amplifier input.
10. Clip LED: The clip LED lights when clipping occurs in the digital section of the TEC4, To eliminate clipping,
reduce the setting of the Tec4’s Master Level. Allow the LED to light occasionally with peak signals.
11. Output Jack: Connect cable from this jack to your amplifier input, also doubles as headphone output.
12. Input Jack: Plug in your instrument here.

SELECTING PROGRAMS
Use either the foot switches (1), or the Up/Down buttons (8). The first three foot switches select programs
and the last foot switch selects banks. To select a specific bank, step on the bank foot switch repeatedly until
the desired bank number appears in LED display (5). Then step on foot switch 1-3 to activate program in
that bank. Only User programs can be selected with the bank foot switch. To select the Factory programs
you must use the Up/Down buttons (8). From the factory, Factory programs are duplicated in all the User
locations.
EDITINGPROGRAMS
Editing programs on the TEC4 has been designed to be efficient and simple. To bypass a currently active
effect, press the Effect Selector button (4) twice. The LED display will read “--”, indicating the effect is
bypassed. You can also turn a bypassed effect on using the same operation. To change an effect or its setting,
press the Effect Selector button (4). This selects the effect to edit. The currently selected effect number will
appear in the LED Display (5). Use the Up/Down buttons (8) to move up or down through the effects and
effect settings. The Store LED will light indicating that you have made changes to the current program. When
the desired effect or setting has been found, you can save your changes by pressing the Store Button (7).
When the Store Button (7) has been pressed, the LED display will begin to flash (6). This is the TEC4 asking
where you would like to save the program. Use the Up/Down Buttons (8) to select desired program number
and press the Store Button (7) one more time to save. The TEC4X provides 30 User program locations for
you to fill with programs of your own. You can also copy a program to a new location by pressing the Store
Button (7) once and using the Up/Down Buttons (8) to select a new User program location and then
pressing the Store Button (7) again.
BYPASSING
To bypass the current program, press the foot switch (1) of the program you are currently using . “bp” will
appear in the LED display (5). To exit program bypass, press any foot switch.
TUNER ACTIVATION
To activate tuner, press and hold the foot switch (1) of the program you are currently using for approximately
2 seconds. “tu” will appear in the LED display (5). To tune, pluck a string repeatedly (a harmonic at the
12th fret is sometimes works best). The LED Display will show the note being tuned while the the second
vertical row of Effect LEDs will show the tuning status of the note. The note is in tune when the green LED
is lit. LEDs lit above the green LED indicate the note is sharp. LEDs lit below the green LED indicate the note
is flat.
FACTORY RESET
Caution, this procedure will restore all User programs in the TEC4X to factory condition.
All User programs will be erased. To factory reset the TEC4X, press and hold both the Compressor
and Reverb buttons while powering up the TEC4. The display will read “rS”. The TEC4 has now restored
all programs to factory condition.

FX DESCRIPTION
COMPRESSION: Levels the peaks in the signal, helping to improve sustain.
DISTORTION: Amplifies the internal signal to an extreme degree, causing the circuitry to clip.
EQUALIZATION: Adjusts the emphasis/de-emphasis of frequencies in the signal
NOISE GATE: Turns off background noise when no signal is present.
CHORUS: Short modulating delay. This produces a "shimmering" type effect.
FLANGE: Short modulating delay, w/signal regeneration. Produces a "jet sounding" type effect
PHASER: Splits the signal, changes the phase of one signal and recombines with the original
TREMOLO: Automatically adjusts the volume of the signal up and down, w/variable speed.
RING MODULATOR: Takes the signals sum and difference and mixes it in with the original.
PIXELLATOR: Degrades the signal by undersampling and then mixing in the original signal.
PITCH SHIFTER: Creates a harmony with the original signal, and then mixes the two together.
DETUNE: Creates a duplicate of the original signal then delays and detunes it slightly.
WAH: Creates a filter that is swept manually through the signal.
AUTO WAH: Sweeps a filter through the signal according to the strength of the attack.
ENVELOPED FLANGE/PHASE: Sweep of the filter/speed is controlled by picking dynamic.
DELAY: Creates a duplicate of the original signal, and repeats it a moment later.
REVERB: Simulates the characteristics of being in a large room or environment.
