1. Input 1: ¼-inch input jack that is intended for electric guitars but will accept other instruments as well. This input
provides the highest gain. It is considered to be the “normal” input.
2. Input 2: This ¼-inch input jack provides 6 dB lower gain so it will allow for a cleaner sound. It can also be useful when
using pedals in front of the amp since it provides more headroom. If guitars are plugged into both inputs, they will mix
together and both will be 6 dB lower in gain.
3. Gain (Lead): Adjust this control clockwise to increase the amount of distortion. Use in its lower ranges to produce less
distorted tones. As you increase the amount of gain, the tonality will shift from a classic rock-type sound to a heavier,
modern tone.
4. Volume (Lead): This controls the overall volume level of the Lead channel only.
5. Channel: This switch selects between the Lead and Rhythm channels.
6. Volume (Rhythm): This controls the overall volume level of the Rhythm channel only.
7. Bass: This controls the bass frequencies for both channels. For a “tighter” bass response, set the Bass control in its
lower ranges.
8. Middle: This controls the middle frequencies for both channels. For a heavier, more distorted sound, set the Middle
control in its lower ranges. For a vintage-style, cleaner tone, set the Middle higher.
9. Treble: This controls the treble frequencies for both channels. Set this control in its higher ranges to brighten up dark-
sounding guitars or, alternately, in its lower ranges to reduce brightness.
10. Reverb/Delay: This switch selects between Delay or Reverb effects. Press switch in to choose Delay.
11. Effects Level: This control increases the effect signal level and mixes it with the instrument’s signal. Turn this control
clockwise to add the desired level of effects.
12. Chorus On: By pressing in, this switch activates a lush Chorus effect.
13. Aux In: This is a 3-conductor, 1/8-inch, stereo jack that allows playback from a Compact Disc, MP3 player or other
audio device. The overall volume level will be determined by the audio device, so start with lower volume levels and
increase as needed.
14. Headphones: This is a 3-conductor, 1/8-inch input jack intended for headphone use. The amplier’s internal speaker
is disconnected when this jack is used.
15. Power Switch: This dual-function component is both an On/Off power switch and a status indicator light. When
illuminated, it shows that your amplier is ready to be played. To turn amplier on, press switch upward. To turn amp off,
press switch downward.

External Speaker: This is a two-conductor, ¼-inch external speaker jack. (Note: This jack is wired in series with the
amp’s internal speaker. Therefore, the internal speaker still functions when an external speaker cabinet is added.)
Footswitch: This amplier provides foot-switchable channels and a “hidden” volume boost feature that works on either
channel to help make solos stand out in the mix. These features may be accessed in the following ways:
1) By connecting a single-function footswitch with a stereo cable to the Footswitch jack on the amplier’s back panel,
users may change channels on the amp while playing. The boost feature will not be active. If a single-function footswitch
is used with a mono cable, such as a guitar cable, users may still change channels on the amp while playing, but the
boost feature will always be active. Kustom offers the model KACFS-100 single-function footswitch which comes with a
stereo cable. It may be ordered from a Kustom dealer.
2) By connecting a dual-function footswitch, both channel-switching and the boost feature may be activated. The
Kustom KACFS201 dual-function footswitch will switch channels and activate the boost function. It may be ordered from
a Kustom dealer.
Note 1: On the KACFS201 footswitch, channel-switching is labeled “Channel” and boost is labeled “Effect.”
Note 2: When no footswitch is attached to the amplier, the “hidden boost” feature is not active.
Effects Loop Send: Use this 2-conductor, ¼-inch jack to connect to the input of an external effects processor or
equalizer. This jack can also be used as a Preamp Out.
Effects Loop Return: Use this 2-conductor, ¼-inch jack to connect to the output of an external effects processor or
equalizer. This jack can also be used as a Power Amp In. (Note: This jack separates the preamp from the power amp. If
using an external effect, the effect will be in series between the Effects Loop Send and Effects Loop Return. The amount
of “dry” signal will be controlled by the external effect.)
1. AC Power Cord Receptacle: AC power cord can be removed for easy
storage and replacement if damaged. Insert the AC cord (provided) rmly into
the AC receptacle. NOTE: Replace the AC power cord if protective jacket is
damaged or ground pin is damaged or removed.
2. Fuse: The fuse is located in a fuse tray just below the receptacle. Replace
only with the same type and size. For your convenience, a spare fuse is located
inside the fuse tray toward the front. To replace fuse, remove AC power cord.
Remove fuse tray by pulling the tab located above the fuse symbol away from
the receptacle.

KG100FX112 Suggested Settings
The following suggested settings will help you dial in a variety of popular tones. Keep in mind, these are starting points to
get you up and running with your KG amplier. Feel free to experiment to achieve your own signature sounds.
CLEAN GUITAR
These settings are for punchy clean tones that are commonly used in Pop, Country, Alternative and many other genres
of music. Use the Rhythm channel with the tone controls set to emphasize brighter sounds. The Bass control should be
adjusted to maintain the clarity of the overall tone. Add Reverb and Chorus as desired.
MEDIUM-GAIN GUITAR
These settings are appropriate for Rock, Blues or other music styles that require a moderate amount of distortion. Use
the Lead channel with the Gain set to its middle ranges. Likewise, keep the Mid control in its middle ranges but increase
the amount of Treble to maintain clarity.
HIGH-GAIN GUITAR
Try these setting ranges when you want to produce the heaviest tones. Notice that the Gain control is cranked up, the
amount of Bass is increased and Midrange is reduced for a heavy, modern vibe. Experiment by adding a bit of Delay to
high-gain solos.
