USER’S GUIDE

Congratulations on your purchase of the Dirty Deed

TM

Distortion Pedal!

The Dirty Deed Distortion Pedal is a high-gain, straight ahead rock distortion pedal that provides
classic, full sounding distortion to a clean amp (Fender), or a bold, rich overdrive to an already
dirty rig (Marshall). The pair of cross-connected MOSFETs provides a rich, warm distortion and
natural tonal character with amp-like touch sensitivity. With the gain control turned down it
works like a subtle overdrive, but with the benefit of the active cut/boost EQ controls. Revel in
the thick, searing distortion and sweet overtones that this pedal dishes out.

HOW IT WORKS

1. Level - Sets the overall level of your signal. CAUTION: The Dirty Deed Distortion is capable of

serious output!

2. Treble - Active +/-12dB of boost or cut in the high frequencies. From 12 o’clock, turn
clockwise to boost the highs, counter-clockwise to cut the treble, enhancing the mids.

3. Bass - Active control provides +/- 12dB of boost or cut. Turn clockwise for thunderous low
end, counter-clockwise to clean up any mud and bring out the all-important mids.

4. Drive - Regulates the amount of distortion the Dirty
Deed is putting out. Low settings give you a tight,
slightly overdriven tone. Turning it up increases the
distortion dramatically, for huge power chords and
endless, singing sustain.

5. True Bypass Footswitch - Removes the circuit from
your guitar’s signal via a hardwired connection from
the input jack to the output jack.

6. Input Jack - Plug in your guitar or other pedal
cable here.

7. Output Jack - Run a cable to the input of your amp
or to the next effect in your chain.

8. Power Jack - We designed this pedal to be
convenient. You can use any 9V to 18V regulated DC
adapter (negative polarity center terminal).

9. Easy Access Battery door (located on back panel) -
When it is not in use, save your battery life by removing
your guitar cable from the Input jack.

LET’S GET STARTED!

1. Put a fresh 9v battery in, or plug in any 9v to 18v regulated DC power supply.

2. Run cables* from your guitar to the input jack, and from the output jack to your amp’s
input. Set in the desired place on your pedal board. (We prefer it early in the chain.)

3. Start with the Treble, Bass and Drive at 12 o’clock and Level at lowest setting. Set your amp
level appropriately.

4. Engage the Dirty Deed Distortion by pressing the footswitch – the LED will come on when
it’s active.

5. Bring the Level up to the desired volume, then start experimenting with the controls.

*Be sure to use good quality, unbalanced, shielded guitar cables to keep the noise to a
minimum. Cheap cables, in addition to making you the target of abuse from your bandmates,
can introduce handling noise (microphonics) and affect the signal to noise ratio of any pedal.

SAMPLE SETTINGS

As you’ve probably figured out, the Dirty Deed Distortion can produce a huge range of tones
from big, chunky power chords to searing, singing lead sounds. The settings below and on the
next page are great starting points.

Fat Rhythm/Lead Tone

This is a great all-around sound for power chords, arpeggiated
rhythm lines and leads alike. Big, fat, and saturated.

Power Crunch

This tone scoops out more of the mids while bumping the
lows and highs for a mean, aggressive sound that’s razor sharp.

Open Rhythm Crunch

An incredibly responsive, dynamic, chord sound. Ease up on
your picking attack and it’s clean, bash it and it will roar like a
lion. Rolling off the bass a touch will help keep rhythm chords
clean and chiming. Depends upon your specific amp, settings
and preferences of course, so experimentation is encouraged!

Big, Saturated Solo Sustain

This lead tone will sing and cry all day long. The saturation
will make it easy to play legato lines but the clarity will let fast
picked passages jump right out too. Just about any note you
land on will sustain until you tell it to stop. This is a gorgeous
solo tone.
