BEFORE SWITCHING ON
After unpacking your amplifier check that it is factory fitted with a three pin 'grounded' (or earthed) plug. Before plugging into the power
supply ensure you are connecting to a grounded earth outlet.
If you should wish to change the factory fitted plug yourself, ensure that the wiring convention applicable to the country where the amplifier is to be
used is strictly conformed to. As an example in the United Kingdom the cable colour code for connections are as follows.
EARTH OR GROUND - GREEN/YELLOW
NEUTRAL - BLUE
LIVE - BROWN
NOTE
This manual has been written for easy access of information. The front and rear panels are graphically illustrated, with each control and
feature numbered. For a description of the function of each control feature, simply check the number with the explanations adjacent to each
panel.
Your Laney amplifier has undergone a thorough two stage, pre-delivery inspection, involving actual play testing.
When you first receive your Laney guitar amplifier, follow these simple procedures:
(i) Ensure that the amplifier is the correct voltage for the country it is to be used in.
ii) Connect your instrument with a high quality shielded instrument cable. You have probably spent considerable money on your amplifier and
guitar - don’t use poor quality cable it won’t do your gear justice.
Please retain your original carton and packaging so in the unlikely event that some time in the future your amplifier should require servicing
you will be able to return it to your dealer securely packed.
Care of your Laney amplifier will prolong it's life.....and yours!

Dear Player,
Thank you very much for purchasing your new Laney product and becoming part
of the worldwide Laney family. Each and every Laney unit is designed and built
with the utmost attention to care and detail, so I trust yours will give you many
years of enjoyment.
Laney products have a heritage which stretches back to 1967 when I first began
building valve amplifiers in my parent’s garage. Since then we have moved on from
strength to strength developing an extensive range of guitar, bass, public address
and keyboard amplification products along with a list of Laney endorsees that
includes some of the world’s most famous and respected musicians. At the same
time we believe we have not lost sight of the reason Laney was founded in the
first place - a dedication to building great sounding amplification for working
musicians.
Warm Regards,
Lyndon Laney CEO
INTRODUCTION
The Dark Art: In an age where guitar players have developed an unhealthy fascination with pre-amp distortion, the fabled sound of a tube
power amp being pushed hard has almost passed into history. Until now that is!
The VH100R features twin footswitchable channels; each with its own footswitchable gain; independent 3 band EQ; independent reverb level
and dedicated FX loop, giving you an unprecedented level of flexibility. You can now go from a super clean shimmer; to a warm clean
crunch; to a stack style distortion; to a full on lead tone, as simply as stepping on a switch - which is included with the amp (FS4). The hand
wired 100W output stage is built to deliver: The harder you drive it, the better it sounds. The VH100R is designed to be used with the
GS412IA and GS412IS cabinets - to enhance the amplifiers huge tonal range and produce stunning tone at any volume.
total flexibility - flexibility of tone and flexibility of use.
Your VH100R should give you years of trouble-free amplification, however please take time to read this manual and familiarise yourself with
the controls as it will allow you to get the best from your amplifier. We hope you enjoy using your VH100R as much as we enjoyed
designing and making it. Best wishes from all at Laney

FRONT PANEL CONTROLS
HI INPUT:
‘Hi’ stands for high gain. This input is designed for the connection of low output level guitars making it well suited
for guitars with single coiled or low gain humbucker type pickups. Use of high gain pickups in this input may drive the preamp
too hard causing a "mushy" sound. Only use good quality guitar cable.
LO INPUT: ‘
high output level guitars. It is useful in obtaining output that is "tight" not "mushy" from high gain humbucker type pickups
Lo’ stands for low gain. This input is attenuated down approximately 50% from the Hi input and is designed for
.
Also use this input for the cleanest full range sound with extended low end response. Only use good quality guitar cable.
GAIN: Sets the level of tube preamplifier gain or how dirty your sound is for the drive channel - Channel B. This channel is
designed to produce full stack style distortion. This control should be used in conjunction with the Volume (4) Setting a low
gain level and medium Volume will give a nice crisp bluesy lead tone, again with the ability to drive the output stage at higher
Volume settings. Setting a medium level on the Gain control and a medium setting on the Volume will give you a punchy hard
rock lead tone, with the ability to again drive the output tubes at higher Volume settings, while setting a high level on the Gain
control and a low setting on the Volume will give you a full on metal lead tone, with the ability to again drive the output tubes at
higher Volume settings Having set the Gain and Volume controls to your desired sound try backing off your guitar volume and
tone controls for lots of other cool sounds. Good tube amplifiers have the unique ability to produce a wide range of sounds by
using only your guitar controls, playing weight and style.

amp gain but pushes the power amp section and makes it work harder giving you a very desirable level of power amp
distortion which is a very pleasing “retro” style sound.
DRIVE SWITCH: Switch in to enable the extra tube drive stage for Channel B, the led will illuminate when active. This gives
you even more gain to play around with using the drive control (6) This channel is designed mainly for full on lead distortion.
This must be switched on for the drive channel to be switchable with the enclosed FS4 footswitch.
DRIVE: This sets the amount of drive sound provided by the extra tube drive stage for Channel B. This varies from subtle
crunch to hi-gain lead break sounds.
BASS, MIDDLE, TREBLE: These are a traditional set of passive tone controls. Passive controls have the advantage of
always sounding musical at any of their settings mainly due to their unique interactive nature. This gives players a more natural
set of tools to create their ideal sound. (Try them all set at midway (5) as a good starting point) (Top row of controls affects
channel B, bottom row of controls affects Channel A)
REVERB: Controls how loud the built in reverb sounds. The reverb in the VH100R is a legendary Sound Enhancements aka
‘Accutronics Reverb’. The only choice for that authentic reverb sound. There are separate controls for Channel A (bottom)
and Channel B (Top)
EFFECTS: Controls the amount of effect returned from an external effects unit via the effects loop/s located on the rear
panel. There are separate controls for channel A (bottom) and channel B (top)
CHANNEL SWITCH: Use this switch to select the active channel, the led will illuminate for the active channel (Top or
bottom row of controls) Channel A (Bottom) produces clean tone and mild overdrive that is reminiscent of a sixties American
tube combo. Channel B (Top) produces more substantial overdrive and distortion that is associated with British tube stacks.
Both channels feature an extra gain stage for more drive which is also footswitchable.
PRESENCE: An output stage tone control. This adjusts the high frequency response - it adjusts your sound from being dull
to giving it edge / sounding sparkly.
RESONANCE: Adjusts level of Power Tube damping. This allows the player to adjust how tight the bass response is - this
will be dependent on what speaker cabinet used. The Resonance allows you to adjust the bass damping to your particular
taste.

VOLUME: Adjusts the overall volume of the clean channel (Channel A) This channel is designed to produce ultra clean tones.
Try cranking the volume control up a little to push the output tubes harder for that real retro sound you can only get with a
quality tube amplifier. Now use your guitar volume control to adjust the amount of distortion. (Wind it up a little for mild
distortion, back it off a little for clean)
BRIGHT: Adds brightness and life to your tones when on the clean channel. Adds edge and picking emphasis when on the
clean drive channel (22-24) This switch has more effect at low clean volume (20)and drive (23) settings. Use in conjunction
with the clean treble control (12) for optimum performance.
DRIVE SWITCH: Switch in to enable the drive stage for the clean channel. When active the led will illuminate. Note: This
switch must be set to ‘on’ to enable remote switching via the FS4 footswitch.
DRIVE: Sets the level of tube preamplifier gain or how dirty your sound is for channel A drive. This channel is designed to
produce clean crunch sounds. This control should be used in conjunction with the Volume (23) Setting low levels of gain with
high levels of volume will give a clean preamplifier sound with tube output stage overdrive. Setting a medium gain level and
medium Volume will give a nice crisp bluesy lead tone, again with the ability to drive the output stage at higher Volume settings.
Setting a high level on the Gain control and a low setting on the Volume will give you a punchy hard rock lead tone, with the
ability to again drive the output tubes at higher Volume settings. Having set the Gain and Volume controls to your desired
sound try backing off your guitar volume and tone controls for lots of other cool sounds. Good tube amplifiers have the

want a very open, warm and semi overdriven sound try reducing the amount of gain (23) and increasing the volume. This
reduces pre amp gain but pushes the power amp section and makes it work harder giving you a very desirable level of power
amp distortion which is a very pleasing “retro” style sound.
STANDBY: Disconnects the HT supply from the Tubes whilst the heaters still keep them warm. This allows you to switch
out of standby and play without waiting for your amplifier to warm up. This is useful after you have sound checked and you are
waiting to go on stage - leave the amp in standby so its ready to go when performance time comes. Always switch off for
short breaks when you don’t want to wait for the tubes to warm up again.
POWER: Main power switch for the unit. The VH100R features delay turn on circuitry to increase tube life, the HT supply to
the tubes gets switched on only after they have warmed up and are ready to go - approx 30 seconds.

POWER INLET SOCKET: Connect to your power source. Make sure the specified voltage is correct for your country!
POWER FUSE: This is the main safety fuse for the unit. The fuse protects the AC power to the amplifier. USE ONLY THE
CORRECT SIZE AND RATING OF FUSE AS SPECIFIED ON THE PANEL. If a fuse blows or fails and a replacement of the
same size and rating is installed and it in turn blows, the amplifier has suffered a malfunction internally and needs immediate
service from a qualified technician. DO NOT TRY USING A FUSE OF HIGHER RATING. Using a fuse that is too large in
current rating may cause serious, irreparable damage to the amplifier and presents a serious fire hazard. The mains fuse
ratings are detailed in the specs section at the rear of this manual
HT FUSE: This fuse protects the DC power to the tubes within the amplifier. USE ONLY THE CORRECT SIZE AND
RATING FUSE AS SPECIFIED ON THE PANEL. If a fuse blows or fails and a replacement of the same size and rating is
installed and it in turn blows, the amplifier has suffered a malfunction, at this point check the output tubes and replace faulty
ones if required. Should tubes not be the problem the amplifier should be checked out by a qualified technician. Do not try
using a fuse of greater value. Using a fuse that is too large in current rating may cause serious, irreparable damage to the
amplifier. Fuses are designed to protect, do not take chances.
LOUDSPEAKERS: Loudspeaker outlets are provided on a series of five jack sockets. The impedance of the
¼” (6.3mm)
loudspeaker/s should be checked and connected to the appropriate socket/s. Using the incorrect sockets will reduce the life
of your output tubes and won’t sound as good and in extreme cases could damage your amplifier.
IMPORTANT: Operation of your VH100R amplifier without a loudspeaker connected could result in expensive failure of
your output transformer. DO NOT OPERATE WITHOUT A LOUDSPEAKER CONNECTED. There are dedicated
optimised outputs for the following loudspeaker combinations: 1*16 ohm, 1*8 ohm, 2*16 ohm, 1*4 ohm, 2*8 ohm.

LINE IN: The Line in socket provides the user with an input to the power amplifier stage. When a Jack is connected to the
Line In socket the preamp signal does not pass to the power amp.
LINE OUT: The line out socket gives the user an output for driving other amplifiers, mixing desks etc. . Can also be useful in
multi-amp setups where a single preamp can drive several VH power stages. This can be done by simply daisy chaining Line outs
to Line ins. The line out is an (unbalanced) line level output.
BIAS: This allows you to bias the amplifier to suit your chosen output tubes. The switch has two positions 5881/6L6 and EL34.
We recommend the use of matched sets of output tubes for best performance. Ensure the switch is in the correct position
otherwise you risk damaging your amplifier.
FOOTSWITCH: This is a 5 pin 180° DIN socket for connection of the dedicated FS4 footswitch enclosed with the amplifier.
The FS4 allows remote switching of Channel A/B, Drive on Channel A, Drive on channel B and Global Reverb
FX RETURN LEVEL: This control serves two purposes:
1) In Side chain mode it controls the mix level of the global FX Return signal (via 14) mixed with the dry signal.
2) In Insert mode it behaves as an overall level control for the global FX Return (via 14)
EFFECTS LOOP RETURN: Connect the output from your external effects to this socket. A notable feature on the
VH100R is that you won’t lose sustain when the FX loops are in use. This is because the power stages are still driven by a tube
FX loop buffer.
EFFECTS LOOP SWITCH: This allows the global effects loop to operate in three distinct modes:
1) Side Chain: The return signal is mixed with the dry signal, the level of FX return is controlled by the FX return
level control. This allows you to set the right mix between the dry signal and the effects signal. Use Side chain
mode for FX units such as delays, flangers etc where a direct signal path is maintained internally to avoid loss of
dynamics through the external FX processor. When using this mode the external FX processor should be switched
to ‘effect only mode’
2) Insert: The return signal is buffered and sent directly to the output tubes, no mixing with the dry signal happens.
The wet/dry mix is adjusted within the external FX processor. The FX return level control then acts as overall level
control allowing you to make up for any insertion loss that may occur in the FX processor. Use this mode when
the whole of the amplifier signal needs routing through any external processors such as graphic EQs etc.
Warning: In insert mode with the FX return level control at minimum the amplifier will have no output, good
normal level for this control is ‘5’ which is approx unity gain.
3) Bypass: The global FX loop circuitry is switched out of circuit altogether.

EFFECTS LOOP SEND: Connect the input of your external effect to this socket. A ‘side chain’ effects loop allows you to
connect external effects such as tremolo’s, chorus and delays to your amplifier. Signal leaves the amplifier via the `Send’ (46)
socket and comes back from the effects via the `Return` (44) socket via the FX return level control (43). Some Effects are
better suited to being between the guitar and amplifer input - these are foot pedal types / distortion / wah wah pedals etc.
Rack mount effects will work better in the FX loop on the amplifer rear. Stomp boxes are normally designed for small signals
such as a guitar output whereas rack mount FX are designed for the higher signal level obtained from an FX send.
CHANNEL B SEND: This line level output provides a signal from the pre-amplifier for routing to external effects processors.
It operates in sidechain mode and any external processors should be set to ‘Effect only Mode’ if at all possible.
CHANNEL B RETURN: Connect the output of the Channel B FX processor here if you only want the effect to be assigned
to channel B. Control the amount of effect with the Channel B effect level control on the front panel. (15)
CHANNEL A+B RETURN: This socket is provided for use when a single external FX processor is going to be used on
both channels, but at different mix levels.
CHANNEL A RETURN: Connect the output of the Channel A FX processor here if you only want the effect to be assigned
to channel B. Control the amount of effect with the Channel B effect level control on the front panel. (16)
CHANNEL A SEND: This line level output provides a signal from the pre-amplifier for routing to external effects
processors. It operates in sidechain mode and any external processors should be set to ‘Effect only Mode’ if at all possible.

TUBE AMPLIFIER SURVIVAL TIPS
Tube amplifiers generally sound much warmer/sweeter than solid state transistor amplifiers but they also need a little more respect due to
the fragile glass tubes themselves. The VH100R uses top quality tubes, six ECC83 preamp tubes, and a matched set of four EL34B-STR output
tubes which should give you years of trouble free service, however like all tube amps; it is important to treat it with a certain amount of
respect.
" Take care when moving the amplifier. Tubes are fragile glass components, they can easily be damaged if thrown in and out of transit vans
etc.
" Make sure the impedance of your cabinets matches the setting on your amplifier. Improper impedance matching will result in reduced
output power output and compromised sound at best and amplifier failure/premature tube failure at worst.
" Allow the amplifier to warm up to room temperature before switching it on, The sudden thermal shock generated can crack the cold
glass tube housing plus any moisture is bad news around high voltage electronics.
" Allow the amplifier to cool down after playing before moving. Hot tubes are more suseptable to damage than cool ones.
Use good quality loudspeaker leads, cheap leads are often not up to the job of handling the large requirements for loudspeakers and can
often short out. Tube amps don't like running into a short circuit.
A tubes life expectancy is based upon a number of factors which include operating temperature, how hard and how often it is played,
vibration due to travel etc. Tubes should be changed in your amplifier If you notice any change in your amplifiers performance etc. They
need not be changed at any regular interval.
Typical problems with preamp tubes can be a crackley noise, hiss, hum and microphony. The preamp tubes can safely be changed with no
action required if they fail or reduce in performance.
Typical output tube problems can be blown HT fuse, sound lacking in punch, sound lacks extreme highs or lows and low level hum. The
Output tubes can be replaced singularly if you replace them with the exact same type AND grade as factory fitted otherwise they
should be replaced as a set. If the same type and grade are used then no rebiasing of the amplifier is required. See the diagram at the bottom
left hand corner to see how to check the tube grade fitted. If you wish to use a different grade of tube then they should only ever be changed
by a qualified service agent due to the grid bias voltage needing adjustment. Do not attempt to rebias your tube amplifier yourself, there are
potentially dangerous voltages inside.
Exact replacement preamp tubes and matched sets of output tubes are available from Laney via your dealer.
To change a tube, switch off the unit and unplug from the mains supply. Wait for the tubes to cool down. Remove the protective grille held in
place with four screws. You should now be able to access the chassis where the tubes are mounted. Preamp tubes are protected with a
screen can, to remove; gently twist the screen can anti clockwise and then pull up. The tube can then be gently pulled out. Take care when
pushing the new tube in to make sure the pins are all aligned properly Output tubes have a spring retainer which must be pushed downwards
before the tube will come out.

General Notes
Amplifier connection: In order to avoid damage, it is advisable to establish and follow a pattern for turning on and off your
equipment. With all system parts connected, turn on source equipment, tape decks, cd players, mixers, effects processors etc.
BEFORE turning on your guitar amplifier. Many products have large transient surges at turn on and off which can cause damage to
your speakers. By turning on your guitar amplifier LAST and making sure its Volume controls are set to minimum any transients
from other equipment will not reach your loudspeakers. Wait until all system parts have stabilised; usually a couple of seconds.
Similarly when turning off your system always turn down the Volume controls on your guitar amplifier and then turn off its power
before turning off other equipment.
Cables: never use shielded or microphone cable for any speaker connections as this will not be substantial enough to handle the
amplifier load and could cause damage to your amplifier system.
Caution: These professional loudspeaker systems are capable of generating very high sound pressure levels. Use care with
placement and operation to avoid exposure to excessive levels that can cause permanent hearing damage. (Refer to guidelines on
page 2)
Servicing: The user should not attempt to service these products. Refer all servicing to qualified service personnel.
