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. At 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.) Grind/Crunch Switch - this switch selects either the CRUNCH or GRIND preamps. Each preamp  
offers a different tonal variation.  
5.) Volume - this is a volume control for the Lead Channel ONLY.  
6.) Channel Select Switch - this switch selects between the Lead or Rhythm Channel.  
7.) Rhythm Channel On LED - when this LED light is on, it indicates that the Rhythm Channel is  
active.  
8.) Gain - adjust this clockwise to increase the amount of gain of the Rhythm Channel. The gain is  
applied before the tone controls.  
9.) Fat/Lean - Selecting Fat allows the 12AX7 tube input stage to be over-driven, giving a fatter sound.  
10.) Volume - this is a volume control for the Rhythm Channel only.  
11.) Bass - this control is the bass control for both channels. 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.  
12.) Middle - this control is the midrange control for both channels. It 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.  
13.) Treble - this is the high frequency tone control for both channels. 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.  
14.) Effects Level - this control adds the digital effects section and mixes it into the main signal. Sixteen  
different effects are available.  
15.) 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.  
16.) Program Select - this switch will select any of sixteen different effects. Page 6 describes each effect  
in detail.  
17.) Effects Active - this switch engages the digital effects section. The Footswitch over-rides this switch  
when it's plugged into the amp.  
18.) Jewel Light - this jewel light lets you know that the amplifier is on.  
19.) Power Switch - this switch turns on and off the AC power to the amp.

HV30 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.) Headphone Jack - this is a 3-conductor stereo jack. The amplifier’s internal speaker is  
disconnected when this jack is used.  
4.) CD/Tape Input - this is a 3-conductor 1/4” jack that allows playback from a Compact Disc or  
Tape player. The volume is controlled by the device plugged into this jack.  
5.) Main FT Switch - this 1/4" stereo jack connects a foot-switch to the amplifier. The tip selects the  
rhythm or lead channel. The ring selects the effects active/off. This foot-switch is not included  
with the amplifier. Kustom model KAC-FS201 is recommended to enjoy all the features.
