Danger! High internal operating voltages.
Do not open the equipment case. There are no user serviceable parts in this
equipment. Refer all servicing to qualied service personnel.
Clean only with a dry cloth.
Condensation can form on the inside of an amplier if it is moved from a cold
environment to a warmer location. Before switching the unit on, it is recommended
that the unit be allowed to reach room temperature.
Unauthorised modication of this equipment is expressly forbidden by Blackstar
Amplication Ltd.
Never push objects of any kind into ventilation slots on the equipment casing.
Do not expose this apparatus to rain, liquids or moisture of any type.

Do not place this product on an unstable trolley, stand or table. The product may
fall, causing serious damage to the product or to persons!
Do not cover or block ventilation slots or openings.
This product should not be placed near a source of heat such as a stove, radiator,
or another heat producing amplier.
Use only the supplied power adaptor which is compatible with the mains voltage
supply in your area.
The power supply adaptor should always be handled carefully and should be
replaced if damaged in any way.
Never break o the earth (ground) pin on the power supply adaptor.
The power supply adaptor should be unplugged when the unit is to be unused for
long periods of time.
Before the unit is switched on, the loudspeaker should be connected as described
in the handbook using the lead recommended by the manufacturer.
Always replace damaged fuses with the correct rating and type.
Never disconnect the protective mains earth connection.
High loudspeaker levels can cause permanent hearing damage. You should
therefore avoid the direct vicinity of loudspeakers operating at high levels. Wear
hearing protection if continuously exposed to high levels.
If the product does not operate normally when the operating instructions are
followed, then refer the product to a qualied service engineer.
Only suitable for safe use under non-tropical climate conditions.

This amplier is only designed and evaluated for safety at a maximum
altitude of 2000m.
The U.S. Government´s Occupational Safety and Health Administration (OSHA) has
specied the following permissible noise level exposures:
Duration Per Day In Hours Sound Level dBA, Slow Response
8 90
6 92
4 95
3 97
2 100
1½ 102
1 105
½ 110
¼ or less 115
According to OSHA, any exposure in excess of the above permissible limits could
result in some hearing loss.
Ear plug protectors in the ear canals or over the ears must be worn when operating
this amplication system in order to prevent a permanent hearing loss if exposure is
in excess of the limits as set forth above. To ensure against potentially dangerous
exposure to high sound pressure levels, it is recommended that all persons exposed to
equipment capable of producing high sound pressure levels such as this amplication
system be protected by hearing protectors while this unit is in operation.
All electrical and electronic products should be disposed of separately
from the municipal waste stream via designated collection facilities
appointed by the government or the local authorities.

Features
The DEPT.10 BOOST is the ultimate high voltage valve boost pedal. Combining a
Class A gain stage and natural sounding passive James-Baxandall EQ this class-
leading pedal is like adding two extra hot valve stages to your amp to ensure the
maximum delivery of precious dynamics and tone. Other features include an all-
valve cut and boost tone section and a high level output specially designed to drive
your valve amp hard.
This is an extremely exible pedal and can be used into a clean amp as a volume
boost, an additional valve equalisation, or to drive your amplier into dynamic valve
overdrive.

Controls
1. Input
Plug your guitar in here. Always use a good quality screened guitar lead.
2. Boost
The Boost knob controls the amount of gain boost that is applied to the guitar
signal. At low levels, a boosted clean sound will be achieved and your amp will
sound more dynamic and full. As the Boost control is increased the amplier will
start to overdrive and the resulting distortion will be rich in valve harmonics and
compression.
3. Low
The tone circuit on the DEPT. 10 BOOST is known as a ‘cut and boost’ circuit.
As the name suggests this allows a range of frequencies to be reduced (i.e. cut)
or increased (i.e. boosted). Turn the control below the centre position to cut the
amount of bass, or past the centre position to boost the bass. Importantly, when
the control is set to 12 o’clock the amount of bass is neither cut nor boosted.
4. High
Similarly, the High control adjusts the amount of cut or boost that will be applied to the
treble, or high, frequencies of your tone. Turn the control below the centre position to
cut the amount of treble, or past the centre position to increase the amount of treble.
Importantly, when the control is set to 12 o’clock’ the amount of treble is neither cut
nor boosted.
5. Output
This output is designed for connection to the input of other pedals or the input of a
valve solid state, digital or hybrid amplier. The built-in buer/line driver is perfect for
preserving your tone when using long cables, or large pedalboards, even driving low
impedance pedals like many wah-wahs.
Always use a good quality screened guitar lead.
6. Valve Guard
Through this guard you can see the ECC83 valve at the heart of your pedal.
WARNING: Do not attempt to remove the xing screws or guard. No user serviceable
parts inside.
7. On/Off LED
When the LED is on the pedal is on. When the LED is not on the pedal is o.
8. On/Off Switch
Press this switch to turn the eect on or o.
9. DC Inlet
For the input of the 9V DC / 500mA adaptor supplied.
Only use the included power supply.
