INTRODUCTION
1
Congratulations on your decision to purchase a amplifier.
products are designed with ease of operation as a primary objective, however to ensure you derive the best from your
Laney
new amplifier, it is important you take time to read this user manual and to familiarise yourself with the control functions and
facilities available
Laney
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
This manual has been written for easy access of information. The front and rear panels of each unit 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 valve amplifier has undergone a thorough two stage, pre-delivery inspection, involving actual play testing, as well
Laney
as valve burn in. Valves are the most important component in your valve amp. However they are also the most fragile
component. The glass envelope and valve filaments can easily be damaged in transit without any apparent signs of damage to
the box, amp or valves. Valve damage is however quite simple to diagnose and even more simple to remedy. These procedures
are explained later in this manual..
Laney
When you first recieve your valve amp, follow these simple procedures:
(i) Ensure that the amplifier is set at the correct voltage for the country it is to be used in.
(ii) Ensure that the speaker is connected to the appropriate socket.
(iii) Connect your instrument with a high quality shielded instrument cable. Use of cheap cables will compromise the sound
of your instrument and your amplifier.
If there is a problem with your valve amplifierLaney

DON'T
DO
PHONE YOUR DEALER!
Care of your amplifier will prolong it's life.....and yours!. If you follow these guidelines your equipment will give you
years of playing pleasure

EFFECTS:
Sets the overall volume level of the clean channel drive sound.
Engages the clean channel drive sound (Also footswitchable)
Controls the low frequency EQ in the pre amplifier.
Controls the mid frequency EQ in the pre amplifier.
Controls the high frequency EQ in the pre amplifier
Controls the level of reverb assigned to each channel
Controls the signal level upon its return from an external processor and blends it to the desired
level with the main signal.
CHANNEL SWITCH:
Selects the required channel which is displayed by an illuminated indicator. The upper
channel produces the clean tone and mild overdrive that is reminiscent of a sixties American valve combo. The
lower channel produces the more substantial overdrive and distortion that is associated with British valve
stacks.
RESONANCE:
Adjusts the 'damping' control of the amplifier speaker enclosure, thereby controlling the
'tightness' of the bass responce. This effect is very cabinet dependant so the switch should be adjusted to taste.
STANDBY:
This switch enables/disengages the high voltage DC to the valves, switching the amplifier from a
'wait state' to an 'active state'. The AC voltage to the heaters is not effected by this switch so that an instant on
of the amplifier is achieved when switching to an active state, so long as the POWER SWITCH has remained in
the ON position. Always switch the amplifier to the 'STANDBY' before turning the main power switch off.
This will prolong valve life

Controls the high frequency material in the power amplifier.
Adjusts the overall volume of the overdrive channel
:
Adjusts the input level of the overdrive channel.
Allows activation of the overdrive section from the front panel.
:
Controls the amount of valve overdrive. The overdrive is applied to the circuit just prior to the gain
control. The drive is engaged only when the drive switch (19) is on. The drive may be operated by the switch or
remotely by the footswitch (FS4) connected on the rear panel.
HI INPUT:
This input provides maximum gain from the instrument to the pre amp. It is extremely useful for
guitars with single coiled or low gain humbucker type pickups. Use of high gain pickups in this input may drive
the pre amp to severely, causing a "mushy" output.

required. Should the valves not be the problem the amplifier should be checked out by a qualified technician. Do
not try using a fuse of greater value. Using fuses that are too large in current rating may cause serious irrepairable
damage to the amplifier. Fuses are designed in to PROTECT, DO NOT take chances.

USEFUL HINTS AND TIPS
7
The following hints and tips are provided so that you can get the best performance out of your valve amplifier. These are only
guidelines and should be adapted for your own preferences:-
Valve amplifiers take a short time to 'warm up' to optimum operating temperature. To get optimum performance out of your amp
1:
allow the amplifier to 'warm up' for three mins. before you begin playing.
The position of an amplifier in a room has an effect upon the overall sound characteristics. If you wish to increase the bass
2:
responce of your amplifier place the amplifier on the floor. If you wish to reduce the bass response of your amplifier place the
amplifier on a stand.
Do not place you amplifier hard up against a wall as this will reduce the air circulating around the back of the unit and may result in
3:
overheating.
4: Connecting your guitar to either the 'HI' or 'LO' input has an effect on the sound, regardless of the guitar type/pickup
configuration. The 'HI' socket provides more gain. The 'LO' socket provides a lower gain. You should experiment with both inputs
to find the one which suits your guitar, style of playing and gives you the most tonally pleasing results.
5: When using the 'BRIGHT SWITCH' on the amplifier keep in mind that it has a greater audible effect the lower the amount of
distortion produced by the preamplifier. At some distortion levels the 'BRIGHT SWITCH' may appear to have no effect at all.

VALVE REPLACEMENT AND TROUBLE SHOOTING
The valves in your new valve amplifier will eventually need replacing due to wear, this is normal with valve amps. In most instances
you should be able to effect valve replacement yourself without incurring the costs of a service engineer. Following are some of the
VALVE REPLACEMENT AND TROUBLE SHOOTINGPS
most likely symptoms of valve malfunction and a suggested method of correction.
Normally valve amps give optimum performance when fitted with matched sets of output valves as factory fitted to all valve
amps. NB: Damage will not occur by not fitting matched sets although the amplifiers performance may be impaired.
SYMPTOM 1
Amp connections have been performed correctly but power light fails to illuminate
SOLUTION 1
Check time delay POWER FUSE and replace if necessary:100-120 Volts 5 Amp time delay
220-240 Volts 2 Amp time delay
SYMPTOM 2
Power light illuminates, no sound out put
SOLUTION 2
Check secondary HT fuse and if blown replace with 1 amp time delay

SYMPTOM 3
Secondary HT fuse (1Amp time delay) blows repeatedly. This is a strong indication of a damaged output valve. The valve
function chart shows the valve layout and the function each performs.
SOLUTION 3
Replace the secondary fuse and turn on the power WITH STANDBY ENGAGED. View the output valves. If one of the
valves fails to light up, replace that valve. If both of the output valves are lit dimily, look directly at the output valves abd
disengage standby. If one of the valves flashes brightly or glows red hot in comparison to the adjacent valves, replace that
particular valve. A simple way to verify that the valve is damaged is to switch the position of the suspect valve and follow the
above procedure. If the valve exhibits the same symptoms in a different valve socket position, you can be certain that the
valve is damaged.
If the output valve checks out OK, another cause of a blown secondary fuse is a damaged Driver pre amp valve No.6. Replace
the Driver pre amp valve No.6 first and follow the above procedures. If the symptom persists, consult a qualified engineer, do
not fit a higher rated fuse.
SYMPTOM 4
No pre amplifier boost on Drive channel
SOLUTION 4
Replace pre amplifier valves No.1&2.
SYMPTOM 5
No clean channel, drive channel OK.
SOLUTION 5
Replace pre amp valve No.3&4
SYMPTOM 6
Slow loss of power
8
SOLUTION 6
Check first for damaged output valves (glowing ,flashing or dead) by using the procedures described in symptom 3. Next check
driver pre amp valve No.6.
All of these trouble shooting procedures can be performed quickly, without the aid of any sophisticated test gear. We suggest that
you always maintain spare valves for emergency purposes. Keep your free of dirt, dust and moisture to prevent
performance failure Never subject your valve amp to environmental conditions that would not be comfortable to you!
Should other customer service be necessary, contact your authorised dealer or call service direct.
