HELP SECTION
1) AMP WILL NOT TURN ON
Check the power to the amp. Check for tripped circuit breakers, unplugged extension cords
or power-strip switches that may be turned off. Check the fuse. If a dark brownish color or
no wire can be seen within the glass tube, then replace. The amp may be perfectly fine but
occasionally a fuse may blow because of high AC voltage surges. After the fuse has been
replaced with the proper Slow Blow value and if the fuse fails again, the amp will require ser-
vicing.
2) NO OUTPUT with POWER light ON
Tubes damaged in shipping will be the primary reason for your amp to not function properly.
Please give us a call to help guide you through this simple repair.
3) KEEP YOUR AMP LOOKING NEW
Use a damp cloth to wipe the controls on the front & rear chassis panels. Wipe the black vinyl
covering with a damp cloth.

CARVIN ENGINEERING DATA
X-100B head
Congratulations on your purchase of your X-100B series IV tube
amplifier. Carvin has been building tube guitar amplifiers since 1949.
Spend time with your new amp and get to know its many sounds.
You'll discover why many creative guitarists have choosen the X-100B
to achieve their sound.
HISTORY OF THE X-100B
The X-100B holds a place dear in the hearts of guitar amp affectionados. The
X100B series tube amps were a mainstay on many arena stages and MTV videos
throughout the 1980's. Artists such as Frank Zappa, Craig Chaquico with Jefferson
Starship, Warrant, Warren Cuccurullo with Missing Persons, and Steve Vai all
played X100B amps. Frank Zappa raved about the Clean channel on this amp.
Steve Vai recorded a song called "Blue Powder" (available on his first solo release
Flexable) featuring the X100B. As a tribute to the original X100B amps, the new
Series IV is badged with the vintage Carvin logo.
DESIGN OVERVIEW
The circuitry of the X-100B allows several layers of control over the dynam-
ics and tone of the amp from the input jack to the speaker output.
PREAMP
Great sounds start with a great preamp. The glassy clean sounds of the
Rhythm channel sparkle even more in the Bright setting. The Lead channel
Drive control is combined with a Hi Gain switch for highly selective control
over the 12AX7 tube overdrive.
TONE CONTROLS
The BASS, MID, TREBLE, and PRESENCE use active circuits to create a
wide range of cut or boost from each control.
5-BAND MASTER EQ
The X-100B features a five band graphic EQ that is assignable to the Lead
or Rhythm channel. An extreme amount of control is available here, allow-
ing you to define your sound in a way not available on most amps.
SWITCHABLE EFFECT LOOP
The X-100B features a switching effect loop for true bypass of effects.
CUSTOM REVERB
The X-100B reverb is custom designed for a full, natural sound. The "long tail"
switching system turns off only the send to let the reverb to decay without being
cut off.
POWER AMP CONTROL
The RMS POWER switch not only reduces maximum output, but also lets you
drive the power amp into saturation at lower volumes while using all four tubes.
GIVE YOURSELF A BOOST OR KEEP IT QUIET
The Master volume control can be configured as a variable volume Boost,
available by footswitch. When engaged, it will boost your amp's output by
up to 9dB for solos or any time you need to stand out in the mix. The footswitch
will MUTE the amp in Master mode, allowing you to switch guitars quietly.

RECEIVING INSPECTION—read before getting started
INSPECT YOUR AMP FOR DAMAGE which may have occurred during shipping.
If damage is found, please notify the shipping company and CARVIN immediately.
SAVE THE CARTON & ALL PACKING MATERIALS. In the event you have to re-
ship your unit, always use the original carton and packing material. This will provide
the best possible protection during shipment. CARVIN and the shipping company are
not liable for any damage caused by improper packing.
SAVE YOUR INVOICE. It will be required for warranty service if needed in the future.
SHIPMENT SHORTAGE. If you find items missing, they may have been shipped
separately. Please allow several days for the rest of your order to arrive before inquir-
ing.
RECORD THE SERIAL NUMBER on the enclosed warranty card or below on
this manual for your records. Keep your portion of the card and return the portion
with your name and comments to us.
EL34 POWER TUBES
Your amp is equipped with EL34 power tubes because of their powerful output
and responsive tone. The characteristics of these power tubes respond to
the wide dynamic range of guitar playing. If you play soft the tubes remain
clean and if you increase your attack they respond accordingly.
HIGH IMPEDANCE GUITAR INPUT
Carvin has long known about the effects of miss-loading a guitar pickup, which
can cause high frequency loss. The X-100B guards against this loss with its
high input impedance. We also considered the capacitance of the average
shielded guitar cable which can reduce the high frequency response of your
guitar pickups. Careful component layout and lead placement control oscilla-
tions and noise without extra capacitance in the circuit, allowing shimmering
highs to be reproduced faithfully.
