Every Black Country Customs product is built with the highest attention to detail and extensively
play tested during its build process by a small group of dedicated players with many years of
experience honing tone.
Black Country Custom products only use the best materials and build techniques with the aim
from the outset to produce the perfect sound. This includes loudspeakers which are hand
selected from each application, to deliver outstanding tonal quality. The speakers we select are
often handmade, using vintage style materials which are acknowledged to give the best guitar
sounds available. All speakers and in particular handmade speakers require several hours
playing before they are broken in and producing their optimum sound.
The result of this attention to detail, high quality raw materials and the optimum build techniques
are quite simply the best sounding ampliers and cabinets
available.
We are sure you will agree.

Power Switch: Always make sure there is a load connected to your amp before turning on. This
load can be a traditional speaker cabinet or a correctly matched dummy load device.
Standby Switch: Allow the amplier to warm up for approximately a minute before switching to the
ON position.
Power Indicator: Indicates that the amplier is powered up.
Presence: boosts the upper mids and highs within the output section. Should be adjusted to your
personal tastes, ‘0’ is a good starting point.
Bass: Adjusts the low-end response of the signal. As the amplier is driven harder and louder you
may nd the need to dial out a little bass. ‘5’ is a good starting point.
Middle: Adjusts the mid frequency response of the signal. As the amplier is driven harder and
louder you may nd the need to alter the middle accordingly. ‘5’ is a good starting point.
Treble: Adjusts the high frequency content of the signal. As the amplier is driven harder and louder
you may nd the need to adjust the high-end response accordingly. ‘5’ is a good starting point.
Master Volume: Used to adjust the overall volume of the amplier to the desired listening level. Due
to the unique way the Master Volume circuit is designed, turning the master volume down does not
alter the output sections content to the overall tone. Keep your amazing valve tone intact whatever
level you decide to play at.
Gain: Adjusts the level of Gain/Distortion present in the signal. Also contributes to the overall listen-
ing level of the amplier.
Bass Input HI : Has a neutral frequency and is great for pedals and boards.
Bass input LO: Has the same tonal characteristics as Bass Input 1 but with a lower gain setting.
Treble Input HI: Has an accentuated high-end response.
Treble input LO: Has the same tonal characteristics as Treble Input 1 but with a lower gain setting.
Channel Jumping: It is possible for a player to mix the tonal and gain characteristics of each input
on the LA100SM by what is known as channel jumping. To do this simply choose the initial channel
you want to use. Let’s say the Bass Input 1, connect your guitar as normal. Now using a regular
patch cable connect Bass Input 2 to an input on the treble channel. Choose input 1 or 2 depending
on how much gain you want. The result, you have more treble in your signal without losing the bass
response generated by the Bass Input. Channel jumping can produce some really great sounds so
do not hesitate to experiment.

     TubeAmplierSurvivalTips
• Tube amps generally sound much warmer/sweeter than solid state transistor ampliers, but
they also need a little more respect due to the fragile glass tubes themselves. The LA100SM uses
top quality 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 care.
• Tubes are fragile glass components and can easily be damaged if not treated with
respect
• Make sure the impedance of your cabinets matches your amplier. Improper
impedance matching will result in reduced output power and compromised sound at best, with am-
plier failure/premature tube failure at worst.
• Allow the amplier to warm up to room temperature before switching it on. If you don’t, the
sudden thermal shock can crack the cold glass tube housing plus any moisture is bad news for high
voltage electronics.
• Allow your amplier to cool down before moving it. Hot tubes are more susceptible to
damage than cool ones. 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 . Although
there isn’t a specic interval for replacement, tubes should be changed if you notice any degradation
of performance.
• Typical problems with pre-amp tubes can be a crackly noise, hiss, hum and microphony.
Other symptoms include a sound lacking in punch, extreme highs or lows and low-level hum. I
nternal failure of the tune can also blow the HT fuse. Exact pre-tested and selected replacement pre-
amp and 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 rear panel held in place with screws. You should now be able to access the
amplier chassis. Pre-amp tubes are protected with screen can. To remove, push down and gently
twist the screen can anticlockwise and then pull up. The tube can then be gently pulled out. Take
care when pushing the new tube in, too make sure the pins are aligned properly with the tube base.
Output tubes have a spring retainer which must be pulled away before the tube will come out.
• Amplier connection: in order to avoid damage, it is advisable to establish and follow a pat-
tern for turning on and off your equipment. Connect and power up all system parts (effects proces-
sors, FX pedals etc.) BEFORE turning on your guitar amplier standby switch. Many products have
large transient surges at turn on and off which can cause damage to your speakers. By turning on
your guitar amplier last and making sure its volume controls are set to a minimum, any transients
from the equipment will not reach your loudspeakers.
