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 amp’s 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 servicing.
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 vinyl
coverings with a damp cloth.
Congratulations on your purchase of the
V3M
all tube amplifier. Carvin has
been building tube guitar amplifiers since 1949. They have been used by top
professionals like Frank Zappa, Steve Vai, Craig Chaquico, Allan Holdsworth,
and other great musicians. You will discover that these amplifiers represent
a significant sound improvement over conventional amplifiers. Spend time
with your new
TECHNICAL DESIGN OF THE V3M
The V3M design criteria was to build a high peformance 3-channel tube guitar amplifier
in a compact, yet powerful package. The V3M has the ability to produce ultra-high gain
and bass heavy sounds with the flexibility to cover all playing styles. The V3M utilizes
new ideas built upon proven tube amplifier technology with an extensive set of features.
FLEXIBLE GAIN STRUCTURES
Each channel of the V3M offers three different gain modes that change the way the
amp reacts to your playing. Different preamp frequencies are enhanced, giving each
setting a different character. Unlike other 3-channel amps, the V3M allows you to
set-up both overdrive channels alike, then change settings to achieve mild or drastic
differences between the two channels.
TONE CONTROLS and EQX
The passive BASS, MID, TREBLE tone controls offer a wide range of tone settings. The
greater range of these controls comes from the use of high impedance 1 meg sealed
controls. The EQX switch on each channel takes it one step further, offering a second
range of tones to control by shifting the frequencies affected by the tone controls.
The PRESENCE control is designed to adjust the “edge” on your sound. It’s range
allows for super-smooth warm sounds at lower settings or turn it up to cut through.
BUILT IN REVERB
The
V3M
system turns off only the send to let the reverb to decay without being cut off.
GIVE YOURSELF A BOOST!
A switchable volume boost is available by footswitch. Set the amount of boost with
the BOOST LEVEL control. When turned on, it will boost your amp’s output up to 6dB
for solos or any time you need to stand out in the mix.
EL84 POWER TUBES
Your amp is equipped with EL84 power tubes because of their unique and responsive
tone. The characteristics of these power tubes respond to the wide dynamic range of
guitar playing. These tubes react to the touch. 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 mis-loading a guitar pickup, which can cause
high frequency loss. The V3M guards against this loss with its ultra 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. Unlike other amplifiers,
we purposely avoided adding capacitance in the preamp to control high frequency oscillations. Instead, we controlled oscillations through careful component layout and lead
placement allowing its shimmering highs to be reproduced.

V3M/V3MC FRONT & REAR PANEL CONTROLS
GETTING STARTED QUICKLY
FIRST, set the 120v/240v AC SWITCH
for the AC voltage in your area.
If you are like most players, you probably want to plug in your new amp
and get started. You can read the rest
of the manual later to learn the finer
points of operating your amp. In order
to get started, you will need your V3M
amp, a 120V or 240V AC grounded
power outlet, your instrument, a standard guitar cable, a speaker cable and
speaker cabinet.
Set the 120/240 SWITCH for the AC
voltage in your area.
Plug in your speaker and set the
“SPEAKER OHMS” switch to match
your speaker. If you have the FS44L
or FS44 footswitch, plug it into the rear
5-pin “FS44(L)” footswitch jack. Or, if
you only have the FS22 footswitch, plug
it into the rear 1/4 inch “FS22” footswitch jack. Turn all volume controls to
“0”. With the amp turned off, you may
now plug it into the proper AC voltage.
Now, plug in your guitar and turn the
POWER switch ON. Wait 60 seconds
for the tubes to warm up, then set the
STANDBY switch to RUN. The amp will
be ready to play. Gradually raise the
channel volume and master volume
control and re-adjust the tone controls
to your liking.
FRONT PANEL
1. POWER SWITCH
The POWER switch is to be utilized as the master ON/OFF switch. As the
amp is turned ON, one of the 3 channel LEDs will illuminate as your ON
indicator. The Boost LED or the V3M internal cage LEDs may also light.
2. STANDBY/RUN SWITCH
After turning the POWER switch ON, wait 60 seconds or more for the
tubes to warm up - then set the STANDBY switch to RUN.
When turning the amp OFF, set the switch to STANDBY first, then
shut off the POWER switch. Use the STANDBY switch if you are
taking a break. This turns the high voltage off, increasing the life of
your power tubes while keeping the power and preamp tube filaments
ON for immediate use.
MASTER SECTION
3. MASTER VOLUME
The MASTER controls the output of all 3 channels and effects.
Once your individual channel levels are set up and balanced, use
the MASTER to change your overall volume.
4. BOOST LED
The GREEN LED will light when the BOOST function is ON. Without
the FS44L-V3M footswitch the BOOST is left ON, acting as an effect
loop return level. This function can only be turned off/on through the
FS44L-V3M footswitch. (see 27. & 28.) Use the rear panel BOOST
LEVEL to add up to 6 dB of volume boost
5. REVERB LEVEL
The REVERB control affects the amount of reverb for all channels.The
reverb may be remotely turned off from the FS44L-V3M footswitch.
CHANNEL SELECTION
The LEDs next to each channel’s DRIVE control indicate which
channel is functioning. To use a footswitch, set both Channel Select
Switches to the UP position.
6. CHANNEL 3 SELECT SWITCH
The CH3/SELECT switch engages/disengages Channel 3. Switch to
up position (CH3) to play CH3, set to down (SELECT) to disengage
CH3 and to use CH1/CH2. Switch to the up position when using
a footswitch.
7. CHANNEL 1/2 SWITCH
The CH1/CH2 sets which channel will be active when CH3 is set
to SELECT. Leave in the up position when connecting a footswitch.

23 24 25 26 27 28 29 30 31 32 33
8. GUITAR INPUT
A standard 1/4” input jack feeds all channels through the SELECT
switches. Use a professional quality guitar cord no longer than 25
feet. Typical cable capacitance should be under 50pf—the longer
the cord, the greater the capacitance (you can measure this with a
capacitance meter). A long cable with high capacitance will reduce
the overall treble response from your pickups.
CHANNEL 3 (CLEAN)
9. VOLUME
Switch to Channel 3 for “clean” playing. Adjust the DRIVE and
VOLUME controls together to set the level for this channel.
10. DRIVE MODE 3-POSITION SWITCH (CH3)
The switch labeled BRIGHT/SOAK is a 3-position switch that
changes the gain structure of the channel. There are three choices
of drive styles:
- “BRIGHT” - adds a high end snap to the preamp, this is ideal for
funk, country or blues.
-“CLASSIC” - (center) A classic, open clean sound with lots of headroom. Turning up the DRIVE adds harmonics and mild compression.
This is ideal for clean jazz, blues and general rhythm.
-“SOAK” - boosts all preamp frequencies. As the DRIVE is turned
up, a vintage snarl is available when played hard. This is ideal for
aggressive blues and rock rhythm.
11. DRIVE CONTROL
For the cleanest sounds with the most headroom, set the DRIVE
control below “5”. As the DRIVE is turned up, tube dynamics and
harmonics are introduced to your sound. Different sounds can be
achieved by setting the DRIVE MODE switch.
12. LED CHANNEL 3 INDICATOR
The Yellow LED will illuminate when CHANNEL 3 is selected.
13. BASS, MID, TREBLE
You can start at 5 on the dial for each of the tone controls. However,
these settings do not represent a normalized (flat) sound. You need
to set them where they sound best! If your sound is too bright, you
may want to reduce the PRESENCE control.
14. EQX SWITCH
Toggle between standard EQ and Expanded EQ. This switch opens a
wider frequency range for the TREBLE, MID and BASS. This provides
an expanded EQ range to work with.

15. PRESENCE
For added clarity, the CH 3 PRESENCE controls only the highest
guitar harmonics in the 5-10k Hz range.
TREBLE control makes this feature even more useful
Careful adjustment with the
CHANNELS 1 & 2 (OVERDRIVE)
The V3M features extensive tone and drive shaping for each channel.
Unlike most 3-channel amplifiers, the V3M allows you to set both
overdrive channels to start with the same sound, then change the
controls to get mild or drastic differences between the two channels.
16. VOLUME
Set the volume of the channel to be used. The level of signal coming
out of the EFFECT SEND will also change. To change the volume of
all channels without upsetting the balance between the 3 channels,
use the MASTER volume control.
17. DRIVE MODE 3-POSITION SWITCH (CH1&2)
The switch labeled INTENSE/THICK is a 3-position switch that
changes the gain structure of the channel. This provides three
choices of distortion styles:
- “INTENSE”- the most gain and sustain, with excellent picking
articulation. The low-end is deep and percussive. Mids and highs
smoothly blend and still cut through. Turning up the Drive adds
more sustain and saturation.
- “CLASSIC”(center)- rich overdrive with a dynamic response.
Turning up the DRIVE knob adds sustain and harmonics.
- “THICK”- designed with a massive low-end, textured mids and
blistering highs. Turning up the DRIVE knob adds sustain to the
highs and fuller low-end harmonics.
18. DRIVE CONTROL
For mild tube saturation, set the DRIVE control below “4”. For
more harmonics and dynamic playing, set the control between 4 & 6.
For full blown overdrive, set the control between 6 and 10 (your
guitar volume should be turned all the way up).
Because the V3M has been “Hot Rodded” with so much gain in
the DRIVE control, you may encounter feedback. If feedback is a
problem, reduce the DRIVE or move the guitar to the side or away
from the speaker(s).
19. LED CHANNEL INDICATORS
The blue LED will illuminate when channel 1 is selected.
The red LED will illuminate when channel 2 is selected.
22 16 17 18 19206 7 8
20. TREBLE, MID, BASS CONTROLS
To start off with, set the BASS, MID & TREBLE controls at their
center (5) position. These controls are to be set according to the
type of sound you want. Try adjusting the PRESENCE control also
when adjusting the treble.
21. EQX
Toggle between standard EQ and Expanded EQ. This switch opens
a wider frequency range for the TREBLE and BASS, providing an
expanded EQ range to work with.
22. PRESENCE
Each channel features a PRESENCE control for added clarity. It’s
frequency range is from the mid to high range of the tonal spectrum.
Careful adjustment with the TREBLE control will make this feature
very useful.
REAR PANEL
23. SPEAKER OUTPUT JACKS
Two 1/4” SPEAKER JACKS are featured to allow use of several speaker
systems at the same time. Calculate the total speaker impedance based
on parallel wiring as the speaker jacks are wired in parallel.
24. SPEAKER IMPEDANCE SWITCH
The IMPEDANCE SWITCH offers the selection of 4 ohm, 8 ohm or
16 ohm to match your speaker system. The correct setting for two 16
ohm speakers or cabinets would be 8 ohms. The correct setting for
two 8 ohm speakers or cabinets would be 4 ohms. Select the proper
impedance. Download Carvin’s Free Impedance Calculator App for
iPhone available in the Apple App Store.
25. LINE OUT
The LINE OUT 1/4” jack is for connecting to power amps or mixers.
This output is “Cabinet Voiced” to prevent excessive bass or treble
going to your mixer. This greatly aids in sound quality because you do
not have to make extreme adjustments to your mixer EQ. The output
level is approx. -23dB less than the speaker output and designed to
drive any professional mixer or power amp.
26. EFFECT LOOP
Effect Loop is a series loop. This means it sends all signals through
your processor. To use the Effect Loop, plug the INPUT of your effects
into the SEND jack and the OUTPUT of your effects into the RETURN
jack. Use shielded cables, not speaker cables. Make sure to adjust your
processor levels so that it’s input is not being overdriven. Adjust the
processor MIX setting to your liking. If your processor has a “Direct
signal ON/OFF” setting, it is usually better to turn it ON.
27. BOOST LEVEL CONTROL
Use the rear panel BOOST LEVEL to add up to 6 dB of volume boost
for solos. This function can be only turned off/on with the FS44L-V3M
footswitch. Without the FS44L-V3M footswitch the BOOST is left ON;
in this case the BOOST LEVEL affects the volume of the amp, acting
as an effect loop return level. The front panel GREEN LED will light
when the BOOST function is ON.
28. FS44L-V3M FOOTSWITCH JACK
To use this footswitch, set the front panel Channel Select switches
to the UP position (see #6&7).
• The CH3 footswitch LED will show CH3 is ON and CH1&2 are off.
• The CH1-2 footswitch LED ON will show CH2 active when CH3 is
turned off.
• The CH1-2 footswitch LED OFF will show CH1 active when CH3
is turned off.
DO NOT use MIDI devices in this jack. Other footswitches will not work.
29. FS22 FOOTSWITCH JACK
To use this footswitch, set the front panel Channel Select switches
to the UP position (see #6&7). The switches on the FS22 footswitch
will control the CH3 and CH1-2 switching. Most foot pedals with 2
switches and a stereo plug will work.
30. POWER MODE SWITCH (OUTPUT)
For maximum output power and dynamics, set the power selector
switch is set to 50W. For early tube saturation at lower level playing,
move this switch to the 22W or 7W settings. The volume reductions
will be 3dB and 6dB.
31. LED CAGE LIGHTING (V3M ONLY)
These switches control the LED accent lighting inside the V3M head.
The LEDs can be set for RED, BLUE or OFF
function on the V3MC combo as there are no LEDs.
32. V3M CAGE
As with any power tubes in an all-steel chassis, the V3M cage will
become hot. The cage will cool down when the amp is placed on
STANDBY when not used.

32. AC POWER & FUSE
Make sure the cord is securely inserted into the back of the unit. Plug
the cord into a grounded “3” prong” power source. No attempt should
ever be made to defeat or use the amp without the ground connected.
The fuse is located inside the AC power cord receptacle. If the fuse
blows, unplug the amp and check the AC power connection, your
speaker connection and all tubes. Replace the fuse with the same type.
If replacing the fuse does not restore the amp to working order, check
the power amp tubes. See Help Section below. If no problem is found
and the fuse blows again, your amp may need service.
33. AC VOLTAGE SWITCH (120V/240V)
It is very important to verify the proper setting before plugging the
amp in. This switch sets the amp to use either 120VAC or 240VAC
ranges from the wall socket. An improper setting may cause a blown
fuse or other damage. The V3M will not require re-biasing if used at
50 or 60Hz, or if the AC voltage switch is changed for travelling to
different areas of the world.
HELP SECTION
A) FEEDBACK FROM THE LEAD CHANNEL
The V3M may feedback when the VOLUME, DRIVE, TREBLE and
PRESENCE are turned all the way up. Like other high-gain tube amps,
this is normal. To help control feedback and noise, reduce the DRIVE
control, or move the guitar to the side or away from the speakers.
Sometimes replacing V1 or V2 (12AX7A) can help reduce feedback.
B) TUBE REPLACEMENT GUIDE
It is not uncommon for tubes to malfunction during shipping or after
a long period of time. If your amp is not working properly, please refer
to the following replacement guide.
1) The 12AX7A preamp tubes are the shorter tubes and are located
in the following order on your chassis:
V1, V2, V3, V4. Replace the tubes if your amp does not work or
sounds muddy or dull. V1 is located closest to the guitar input
and is the input tube affecting all channels. V2 is the main drive
tube for channels 1&2. Replacing V3 will correct problems with
channel 3 and the effect return. Replace V4 if no output is heard
when putting a signal through the effect return.
2) If there is no output after replacing the preamp tubes, or if the
fuse blows, try replacing the EL84 output tubes. The amp should
be rebaised by a qualified technician after replacing the output
tubes. Set to 80mA across the standby switch (with switch off).
3) If the AC fuse should blow and turn the amp off, try replacing the
power tubes. One of these tubes might be faulty.
