Kustom QUAD JR User manual

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.

longue au bruit intense. Les autorites competentes en
reglementation de bruit ont defini les expositions tolerees
aux niveaux de bruits:
Selon les autorites, toute exposition dans les limites

d’expositions superieures aux limites precitees il est
recommande, afin de se premunir contre les expositions
aux pressions acoustiques eIevees potentielIement
dangeureuses, aux personnes exposees aux
equipements capables de delivrer de telles puissances,

1.) Line Output - this is a 3 cond. XLR output jack for plugging into Lo-Z microphone inputs as found on PA or
recording mixers. It is intended in place of external mics or used as a built in direct box.
2.) CD/Tape Input - this 1/4" 3 conductor jack will allow you to plug in a CD player, tape or any other source to practice
along with. It sums the left and right signals into a mono signal. To control the volume of the source, adjust the output
volume of the device.
3.) Guitar Input Jack -this is a 1/4" 2 conductor input jack for plugging in your instrument. It is intended for guitars but

the signal is unaltered Turning it counterclockwise, the low will be rolled off -12db.
14.) Middle - this control is the midrange control for the instrument channel, and is passive and set to shelve frequencies
at 1KHz. Turning it fully clockwise, the signal is unaltered. Turning it counterclockwise, the low will be rolled off -
12db.
15.) Preamp Switch - when engaged, this switch will boost the treble sound of the Rhythm channel. It boosts 3 KHz by
+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.
21.) Program Select - this switch will select any of eight different effects. 2- Reverbs, 2- Echos, Chorus, Chorus/Reverb,
Flange/Reverb and Tremolo.
22.) Jewel Light - this jewel light lets you know that the amplifier is on.
23.) Power Switch - this switch turns on and off theAC power to the amp.
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).
Footswitch Jack - this is a 3 conductor 1/4" jack. This is for hooking up a footswitch to switch channels and to turn
on/off the effects section.
B.A.L.L.S. (Ballistic Audio Loudness Level Saturation)- adjust this clockwise to increase the amount of distortion
you Add lower ranges of the control, you get a less distorted sound, a "bluesy"tone .As you increase the gain, you
add Tremendous amounts of distortion to the signal for a harder edged "crunch"tone.

Suggested Settings
(These settings are general starting points. They
are designed to get you close to the sound you
are looking for. If the control is not shown, then it
doesn't apply to this particular sound. )
Clean Rhythm Guitar - these settings are the basic clean sounds and for general rhythm
guitar, country lead guitar, and funky/chunky rhythm sounds.
The bottom end depends on what type of guitar you are using. Add Reverb and Chorus
as desired.
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.
