Congratulations! You are now the proud owner of a Kustom QUAD JR. half-stack guitar amplifier. With this model,
you will be able to easily produce a wide spectrum of killer sounds, from studio-quality clean tones to crunchy rhythm
riffs and all-out screaming solo sounds. Two channels, dual 3-band EQ controls, and eight 24-bit digital effects
provide on-the-fly flexibility that works in any playing environment.
Unlike most 100-watt, solid-state amp stacks, your QUAD JR. does not need a second speaker cabinet to deliver its
full power potential. Instead, it delivers all 100 watts straight into its Celestion™ loaded, 412 speaker cabinet. With its
special hot-rodded circuitry, you'll notice that the QUAD JR. excels at heavy, modern rock. Prepare to be blown away!
Kustom wishes you many years of enjoyment with your QUAD JR. amplifier.

IMPORTANT SAFETY INSTRUCTIONS
Danger
Exposure to extremely high noise levels may cause a
permanent hearing loss. Individuals vary considerably to
noise induced hearing loss but nearly everyone will lose
some hearing if exposed to sufficiently intense noise for a
sufficient time.
1. Read all safety and operating instructions before using this
product.
2. All safety and operating instructions should be kept for
future reference.
3. Read and understand all warnings listed on the operating
instructions.
The U.S. Government's Occupational Safety and Health
Administration (OSHA) has specified the following
permissible noise level exposures:
4 . Follow all operating instructions to operate this product.
5. This product should not be used near water, i.e. Bathtub,
sink,swimming pool, wet basement, etc.
6. Only use dry cloth to clean this product.

8. Do not install this product near any heat sources ;such
as,radiators, heat registers, stove or other apparatus
(including heat producing amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or
grounding-type plug. A polarized plug has two blades with
one wider than the 0ther.A grounding-type plug has two
blades and a third grounding prong. The wide blade or the
third prong are provided for your safety If the provided plug
does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.
According to OSHA, any exposure in the above permissible
limits could result in some hearing loss. Ear plugs or
protectors in the ear canal or over the ears must be worn
when operating this amplification system in order to prevent
a permanent hearing loss. If exposure in excess of the limits
as put forth above, to insure against potentially harmful
exposure to high sound pressure levels, it is recommended
that all persons exposed to equipment capable of inducing
high sound pressure levels, such as this amplification
system, be protected by hearing protectors while this unit is
in operation.
10. Protect the power cord being walked on or pinched,
particularly at Plugs, convenience receptacles and the point
where they exit from the apparatus. Do not break the ground
pin of the power supply cord.
CAUTION
RISK OF ELECTRIC SHOCK

+6 db.
16.) Treble - this is the high frequency tone control. It is passive and set to shelve frequencies at 3KHz on the instrument
channel. Turning it fully clockwise, the signal is unaltered. Turning it counterclockwise, the highs will be rolled off -
12db.
17.) Rhythm Channel On LED - when this LED light is on, it indicates that the Rhythm Channel is on.
18.) Volume - this is a volume control for the Rhythm Channel ONLY.
19.) Effects On/Off - this switch engages the digital effects section.
20.) Effects Level - this control adds the digital effects section and mixes it into the main signal buss. Several different
effects are available.

Back Panel - (not pictured)
Speaker Out - this is a 2 conductor 1/4" speaker output jack. Rating is 4 ohms minimum.
Line Output - this is a 2 conductor 1/4" line output jack. This will allow an external amplifier or mixing board to be
supplied with the signal from this amp.
Effects Loop I/O - This is an effects Insert jack. Tip send (preamp out) and ring return (power amp in).

Blues Lead or Mellow Crunch - this setting is particularly useful in blues or softer rock songs and it
is good for leads as well as rhythm parts. It is good for power chords in back of leads. You need to
switch to the lead channel to make these settings work. Blues, depending on the guitar you use,
usually adds treble but with more midrange and a "fat" bottom end. This setting does not have as
much gain as full out crunch, adjust the gain control to the amount of distortion you desire. Blues
usually has a reverb trail on the notes. Chorus is sometimes used to create a vibrato style sound.
Adjust to taste.

Alternative/Harder Edged Rock - this setting will deliver more of a cutting tone. Whether used for
rhythm or lead sounds, it will "cut" through the drums and get you heard. If you need more "grunge",
increase the gain control for more distortion. This style of music requires a slightly thinner, harder
edged tone full of midrange. Less reverb is required as it tends to muddy up faster songs but Chorus
give the tone a fatter fuller sound. Adjust to taste.

Heavy Metal/Maximum Crunch - this setting is a good starting point for the "notched out middle"
sounds associated with metal and heavy alternative sounds. Adjust the Treble, Lows, Reverb and
Chorus to taste. Usually, for a rhythm tone, you want to have more lower end and less for leads.
Distortion is an integral part of this style of music and this amp delivers it quite well.
