WARNING! - Important safety instructions
WARNING: This apparatus must be earthed!
A. PLEASE read this instruction manual carefully before switching on.
!
B. ALWAYS use the supplied mains lead, if a replacement is required please contact your
authorised Marshall Dealer.
C. NEVER attempt to bypass the fuses or fit ones of the incorrect value.
D. DO NOT attempt to remove the amplifier chassis, there are no user serviceable parts.
E. Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has been damaged in any way, such as when the
power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the
apparatus, the apparatus has been exposed to rain or moisture, does not operate normally
or has been dropped.
F. NEVER use an amplifier in damp or wet conditions. No objects filled with liquids should be placed
on the apparatus. When cleaning, only use a dry cloth.
G. ALWAYS unplug this apparatus during lightning storms or if unused for long periods of time.
H. PROTECT the power cord from being walked on or pinched particularly at plugs,
convenience receptacles and at the point where they exit from the apparatus.
I. DO NOT switch the amplifier on without the loudspeakers connected.
➲
CAUTION: Any changes or modifications not expressly approved by the party responsible for
compliance may void the users authority to operate the equipment.
➲
Note: It is recommended that all audio cables, with the exception of the speaker lead(s), used to
connect to the MG15MSII are of a high quality screened type.
These should not exceed 10 metres in length.
Always use a non-screened Marshall approved speaker lead when connecting an extension cabinet to
the MG15MSII.
➲ WARNING: Always ensure free movement of air around the amplifier!
USA ONLY - DO NOT defeat the purpose of the polarised or grounding type plug. A polarised
plug has two blades with one wider than the other. A grounding type plug has two blades and a
third grounding prong. The wide blade or the third prong are provided for your safety. When the
provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.
Follow all instructions and heed all warnings

tone can range from traditional and woody
sounding (setting at 10), to balls-to-the-wall
(setting at midway), to aggressive, ‘scooped’
and modern (setting at 0)…and all points in-
between.
1. INPUT jack
Use a good quality (screened) guitar cable to
plug your guitar in here.
2. Clean VOLUME control
When the OD Select switch is ‘out’, this
control adjusts the volume of the Clean
Channel. At low settings the sound will be very
clean with a bell-like ring. Turning this control
above half way will introduce a desirable,
bluesy distortion as the power amplifier is
driven into ‘crunch mode’.
8. EQ TREBLE control
This control affects the treble or top end of
your sound. Increasing the amount of treble will
give a glassy edge to your clean sounds and
increase the definition on low gain overdrive or
the amount of aggressive ‘fizz’ and ‘cut’ on high
gain tones.
3. OD (Overdrive) SELECT switch
Depressing the Overdrive Select Switch will
engage the Overdrive Channel.
9. Reverb LEVEL control
Increasing the Reverb Level control will mix
more of the naturally voiced spring reverb
signal into your sound – as you’ll find, you can
go from subtle to surf at the mere twist of this
control!
4. Overdrive GAIN control
Turning up the Overdrive Gain Control will
increase the amount of distortion generated in
the Overdrive channel. Low gain settings will
produce classic rock and blues tones. Crank
the Gain for fat and aggressive sounds that are
perfect for soloing or hard rock and nu-metal
riffing.
10. FDD (Frequency Dependant
Damping) Switch
Marshall’s proprietary FDD circuit accurately
mimics the way an all-valve amplifier interacts
with the loudspeaker and adds a width and
depth to your sound which has been
unachievable in an affordable solid-state
amplifier…until now!
5. Overdrive VOLUME control
Amazingly enough, this control adjusts the
volume of the Overdrive channel! The louder
this channel is set, the ‘looser’ the amplifier will
sound and feel. This behaviour is exactly what
a good all-valve amplifier does and is a result
of our proprietary FDD circuitry.
11. CD IN & EMULATED LINE OUT
jack
The MG15MSII cleverly combine the Line Out
and CD Input functions. If you want to jam to
your favourite CD or tape, merely connect the
headphone output of your CD or tape player
here, adjust the CD / TAPE player’s volume to
match that of your guitar and ‘hey-presto’ –
you’ve got the perfect ‘play-along’ practice
system. Alternatively, you can use this socket
to connect the MG15MSII to your multi-track
recording machine and you’ll get a great
speaker emulated guitar sound direct to disk or
tape.
6. EQ BASS control
This control affects the bass or bottom end of
your sound. Increasing the bass control will add
warmth to your clean and balls to your
overdrive tones.
7. EQ CONTOUR control
This highly effective tone control works by
radically modifying the mid-range (body). The

HELPFUL HINT: for ‘silent’ recording merely
plug an unconnected jack plug into the
headphone socket and you’ll disconnect the
MG15MSII speaker cabinets.
13. POWER Switch & LED
The power switch turns your amplifier on and
off. The LED will be lit when your amplifier is on
and will not be lit when the amplifier is switched
off.
12. EMULATED HEADPHONES jack
Note: Before connecting to the mains
electricity supply, always ensure that your
amplifier is compatible with your electricity
supply, as detailed on the rear panel.
Plug your headphones here for a killer
speaker emulated sound! Doing this mutes
your MG15MSII speaker cabinets for ‘silent’
practice.
Please ensure the amplifier is switched off
and unplugged from the mains electricity
supply before being moved.

2. LOUDSPEAKER Outputs
Connect the two loudspeaker cabinets
provided to the speaker outputs using the
speaker leads supplied.
The MG amplifier is provided with a detachable
mains (power) lead which is connected here.
The specific mains input voltage rating that your
amplifier requires is clearly indicated on the
back panel. Before connecting to the mains for
the first time please make sure that your
amplifier is compatible with your electricity
supply.
If you would like to use your MG15MSII
amplifier head with another speaker system
(such as a full size 4 x 12" cabinet), ensure that
the amplifier is provided with a total load equal
to or greater than 8 ohms.
Always use a non-screened Marshall
approved speaker lead when connecting an
extension cabinet to these units.
