Fuzz™, a most unique fuzz pedal that incorporates a six-position “Tweak”

switch to voice your fuzz tone the way you want it. You can start using your
Tweak Fuzz right away and you’ll immediately notice that the soft clipping
and natural compression make it extremely player-friendly. However, you
might want to first read through these instructions to gain valuable infor­mation, which will enhance your enjoyment of this unique product.

For Tone That Sets You Apart

Controls

Tweak – This rotary switch engages one of six pre-set EQ resonances that

give an overall “flavor” to the Tweak Fuzz, rolling off the bottom end and
influencing the behavior of the Gain control. Some describe the extreme
settings of the Tweak control like the difference between the brightness of
a bridge pickup and the warmth of a neck pickup – with four in-between
settings. Each of the six frequencies was specifically chosen and voiced to
enhance rich, even harmonics and bring out the most flattering qualities of
your guitar or bass – yes, the Tweak Fuzz also sounds amazing with a bass.

Gain – This knob controls the amount of fuzz, also called square wave clip­ping distortion. It can go from mildly distorted to all-out fuzz fury. The mild
settings are great for chords and funky rhythm strums. The all-out settings
work best with single note riffs and two-note power chords.

Volume – This knob sets the overall volume to the optimum level. Whether
you want to set it to match the bypassed signal or whether you want a big
boost when you engage your Tweak Fuzz: it’s your decision.

Footswitch – Use this to turn the Tweak Fuzz on or off. When the Tweak
Fuzz is on, the LED indicator is lit. When it’s off, the unit is true-bypassed,
effectively removing the circuit from your guitar’s signal chain. This allows
your guitar’s signal to pass through the Tweak Fuzz without affecting your
tone or gain.

Battery

To make your Tweak Fuzz work, you’ll need to insure that a fresh battery
is installed. If not, you’ll need to install one, or connect a regulated 9V DC
power supply – see below for details.

To replace the battery, simply:

a Make sure your Tweak Fuzz is not connected to a DC Power Supply
(see below).
b Remove the four screws on the underside of the box and disassemble
the chassis.

c Remove the old battery from the clip, if applicable.
d Install a fresh 9 volt alkaline battery, taking care to properly orient the “+”

and “-“ terminals (see Figure 1 for proper battery orientation).
e Reassemble the chassis and replace the screws.

When storing the Tweak Fuzz, or when it is not in use, make sure no cable
or plug is inserted into the “Input” jack, as this will shorten battery life. As
an alternative to a battery, you can use a regulated DC power supply (“wall
wart”) ranging from 9 – 12 volts, for example a Boss
#PS200R. These are available at electronics supply stores and most music
stores.
