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.
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!

INTRODUCTION
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.
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
The VH100R offers total
flexibility - flexibility of tone and flexibility of use.
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

HI INPUT:
LO INPUT: ‘
.
: It is useful to experiment with the gain and volume controls. If you want a very
open, warm and semi overdriven sound try reducing the amount of gain (3) 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.
‘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’ stands for low gain. This input is attenuated down approximately 50% from the Hi input and is designed for high
output level guitars. It is useful in obtaining output that is "tight" not "mushy" from high gain humbucker type pickups 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.
VOLUME Sets the overall ‘loudness’ of Channel B.

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 unique ability to produce a wide range of sounds by using only
your guitar controls, playing weight and style.
VOLUME: Sets the overall ‘loudness’ of Channel A drive.
-
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.
(Always switch off and disconnect the power cord when not in use)
It is useful to experiment with the gain and volume controls. If you 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.

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
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.
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
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
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.
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)
