Kustom 15H, V15 User Manual

V15 & 15H
GUITAR AMPLIFIERS
OWNER’S MANUAL
Congratulations on the purchase of your Kustom Defender Amplier.
Your Defender Model draws on decades of amp design and manufacturing experience at Kustom. This model was built from the ground
up to offer world-class tone, useful features and reliable performance. Inside this manual, you’ll nd valuable information about the amp’s controls and specications. Being familiar with its features will help you effectively dial in different tones. We wish you many years of enjoyment with your Kustom amplier.

1. INPUT JACK: This is a ¼”, 2-conductor input for plugging in your instrument. It is intended for guitar but will accept other instruments as well.
2. VOLUME: This control determines the overall volume level of the amplier. Due to the simplicity of the Defender V15’s
all-tube circuitry, a wide range of tones can be obtained with the use of this control alone.
For example, when set in its lower ranges, the sound is clean and snappy. As the Volume control is turned up, light overdrive is generated by the amp’s all-tube circuitry. This overdrive occurs naturally and is not created by any internal distortion circuit. As the Volume control is turned higher (clockwise), you’ll hear increased natural drive and compression that is great for crunchy rhythms and sustaining guitar solos. In essence, the Defender V15 generates classic overdriven tube amp tone but at lower, more manageable volume levels. (Although you may be surprised by the amount of volume that the Defender V15 & 15H can generate, so watch your ears!)
3. BASS RESPONSE: This control varies the low frequency response and changes how the amp sounds and feels. When turned all the way to the left, the bass notes will have a looser, less focused sound reminiscent of vintage American tube amps. As you turn the knob clockwise, the bass notes gain a tighter, thicker attack with a distinctly British avor.
4. TONE: The Tone control adjusts the balance of low, middle and high frequencies. When set at 12 o’clock, thicker control provides an even balance of all frequencies. When turned to the left, bass notes are emphasized providing a thicker tone. Turning the knob clockwise adds high frequencies to the tone. Higher settings will provide more bite and help you cut through the mix.

5. OUTPUT POWER SELECT: This control changes the output power of the amplier. Set to 15 Watts for maximum volume and more headroom before the sound “breaks up” as a result of overdriving the tubes. Set to 4 Watts to achieve this distorted sound at lower volumes.
6. POWER: 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 your amplier on, press switch upward. To turn amp off, press switch downward.
Note: After the power switch is turned on, the tubes must warm up for approximately one minute before you will hear sound from your
amplier.

1. AC POWER CORD RECEPTACLE: Insert the AC cord (provided) rmly into the AC connector. NOTE: Replace the AC power cord if protective jacket is damaged or ground pin is damaged or removed. The fuse is located in a housing just below the receptacle. Replace only with same type and size. To remove the fuse, remove AC power cord and pull out on the tab above the fuse symbol located on the
fuse carriage. Place the new fuse in the carriage clip and re-insert.
NOTE: To prevent an electrical hazard, DO NOT replace fuse without using the fuse carriage. Replace the fuse carriage if lost or damaged before re-inserting the AC power cord.
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.
3: SPEAKER OUTPUTS: These 1/4” jacks are provided to connect the internal and/or external speakers to the V15. THE AMPLIFIER SHOULD NEVER BE OPERATED WITHOUT A SPEAKER PLUGGED INTO A SPEAKER JACK.
4. DIRECT OUT: The XLR Direct Out jack is designed to connect the amplier to a recording or live mixer. The output is speaker-
emulated, and mimics the sound of the Celestion loudspeaker. This output is very useful for direct recording, and especially helpful for live applications since it eliminates a live microphone on stage and the resulting feedback potential.
5. GROUND LIFT: The Ground Lift switch disconnects pin 1 of the XLR Direct Out jack to eliminate a “ground loop” hum. A ground loop
can exist when the amp and the mixer it is plugged into are connected to grounded outlets that are in physically different locations and/ or on different circuits, and should only be used if there is an audible hum. Pressing the ground lift does not disconnect the ground connection from the chassis.
