1.) Guitar Input Jack - this is a 1/4" 2-conductor input jack for plugging in your instrument. It is intended for guitars but
will accept other instruments as well.
2.) Lead Channel On LED - when this LED light is on, it indicates that the Lead Channel is active.
3.) Gain - adjust this clockwise to increase the amount of distortion. Lower ranges of the control, you get a less
distorted sound. As you increase the gain, you add tremendous amounts of distortion to the signal for a harder
edged "crunch" tone.
4.) Gain Boost Switch - this switch will add more gain to the Lead Channel.
5.) Volume - this is a volume control for the Lead Channel ONLY.
6.) Grind/Punch Switch - this switch selects either the PUNCH or GRIND preamps. Each preamp offers a different
tonal variation.
7.) Bass - this control is the bass control for the Lead Channel. It is passive and set to shelve frequencies at 100Hz.
Turning it fully clockwise, the signal is unaltered. Turning it counterclockwise, the low will be rolled off -12db.
8.) Middle - this control is the midrange control for the for the Lead 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.
9.) Treble - this is the high frequency tone control for the Lead Channel. 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.
10.) Channel Select Switch - this switch selects between the Lead or Rhythm Channel.
11.) Rhythm Channel On LED - when this LED light is on, it indicates that the Rhythm Channel is active.
12.) Gain - adjust this clockwise to increase the amount of gain of the Rhythm Channel. The gain is applied before the
tone controls.
13.) Fat/Lean - Selecting Fat allows the 12AX7 tube input stage to be over-driven, giving a fatter sound.
14.) Volume - this is a volume control for the Rhythm Channel only.
15.) Bass - this control is the bass control for the Rhythm Channel. It is passive and set to shelve frequencies at 100Hz.
Turning it fully clockwise, the signal is unaltered. Turning it counterclockwise, the low will be rolled off -12db.
16.) Overdrive - this increases the gain of the second stage of the 12AX7 preamp tube on the Rhythm Channel.
17.) Middle - this control is the midrange control for the Rhythm 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.
18.) Treble - this is the high frequency tone control for the Rhythm Channel. 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.
19.) Boost - this is a master volume for both the Lead and Rhythm Channels. It’s an overall volume control for the
amplifier.
20.) Effects Level - this control adds the digital effects section and mixes it into the main signal. Sixteen different
effects are available.
21.) Toggle Tap - This momentary switch performs different functions, depending on which effect is selected. Page 6
describes each effect in detail and how to enhance its usefulness with this switch.
22.) Program Select - this switch will select any of sixteen different effects. Page 6 describes each effect in detail.
23.) Effects Active - this switch engages the digital effects section. The footswitch over-rides this switch when it's
plugged into the amp.
24.) Jewel Light - this jewel light lets you know that the amplifier is on.
25.) Power Switch - this switch turns on and off the AC power to the amp.

HV™65 Effects
Effects Level this control adds the digital effects section and mixes it into the main signal. Sixteen
different effects are available.
Program Select this switch will select any of the sixteen different effects.
Effects Active this switch engages the digital effects section. The footswitch over-rides this switch
when it's plugged into the amp.
Toggle Tap this switch is a dual function depending on which effects program is selected. On “toggle”
effects, this button pages through alternate variations of the effect. For example, for the Spring Reverb,
it pages through 3 different degrees of brightness. On “tap” effects, this button selects the rate time at
which the effect cycles, by tapping the switch twice. For example, for the Delay setting, it selects the
amount of time between delay repeats (If the 2nd tap is beyond the maximum setting, the time will
default to the longest available choice).

Effects Module Memory Aside from all the versatility of the built-in effects, the effects module in your
Kustom amplifier has the ability to store your favorite sounds. All the most recent changes to the Toggle
Tap button are saved in each of the 16 effect locations. For example, If you tap in your favorite delay
time, then go to chorus, and then go back to delay, your own tapped delay time will still be saved.
These setting changes are also retained when powering down the amplifier.
To Restore Factory Settings If you ever want to restore the effects to the factory default settings, you
can do this by selecting Program 1 (Delay/Reverb), then holding the tap switch down and
simultaneously selecting Program 2 (Trem/Reverb).

Jacks located on chassis bottom in sequence shown above
1.) External Speaker - this is a 2-conductor 1/4" speaker output jack. Rating is 8 ohms minimum. The signal path to
the internal speakers is disconnected when using this jack. Make absolute sure that a 2-conductors speaker cord is
used and it is plugged in to the external speaker cabinet before plugging into this jack. Failure to do so could result
in electrical shock or damage to the amplifier. It is also highly recommended to turn off the AC mains power to the
amplifier before plugging or unplugging any speakers to this jack.
2.) Direct (SPKR Emulated) - this is a 3-conductor. 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. Great effort was
made in emulating the actual speaker sound.
3.) Effects Return - This switching 2-conductor 1/4" line level input jack is the return from an external signal
processor such as a digital delay or EQ. By using this jack, you break the signal path between the preamp output
and power amp input.
4.) Effects Send - this 2-conductor 1/4" line level output jack is the send to an external signal processor. It can also
be used as a preamp output and it does not break the signal path between the power amp and preamp. The front
panel volume and tone controls do affect the output of this jack. The output of the speaker is not emulated, so this
is not a good choice as a substitute for mic-ing the amp.
5.) CD/Tape Input - this is a 3-conductor 1/4" line level input jack. The right and left channels are summed together on
the ring and tip and sent to the preamps master mix section. The boost volume on the front panel is the only control
that has any affect on this input. It acts as a master volume.
6.) Ext Tap FT Switch - this 2-conductor 1/4" switching jack replaces the Toggle Tap switch on the top panel. This is a
nice feature to have, because it allows you to change the selected effect parameter in real time with your foot while
playing. Using the jack disables the top panel switch. The jack accepts a non-LED single button momentary foot-
switch. This foot-switch is not included with the amplifier. Kustom model KACFS-101M can be purchased
separately. Most keyboard sustain pedals are this type and can also be used. NOTE: most single button foot
switches used on analog instrument amplifiers are alternate contact (the "push on/push off" type). Using this type of
switch will give unsatisfactory results but will not damage the amplifier.
7.) Main FT Switch - this 1/4" stereo jack connects a foot-switch to the amplifier. It uses a special circuit to decode the
3 switches through a simple stereo cable. The tip selects the rhythm or lead channel. The ring is multifunction for
the overdrive on/off switch and the effects active/off switch. This foot-switch is not included with the amplifier.
Kustom model KACFS-301 must be used to enjoy all the features. In an emergency, a mono single-conductor
shielded instrument cable and single button foot-switch can be used to allow switching of the channels only. In this
setup, the LEDs will not be visible, but at least the foot-switch will select Rhythm or Lead channels. The top panel
overdrive on/off and effects active/off switches will still function.

extend downward to allow for tilt back operation. Twist while applying pressure to release these
feet. Once extended, twist further to lock in position. Reverse process for retracting.
2.) AC Power Cord Receptacle - AC power cord can be removed for easy storage and
replacement if damaged. Insert the AC cord (provided) firmly into the AC receptacle. NOTE:
Replace the AC power cord if protective jacket is damaged or ground pin is damaged or
removed.
3.) Fuse - The fuse is located in a fuse tray just below the receptacle. Replace only with 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.
