From Jim Marshall

I would like to thank you personally for selecting

the new 15 Watt, MG15MSII Microstack.

As a musician myself I fully understand the
necessity of achieving the right tone and feel to
help inspire musicians to reach their full creative
potential – be they aspiring beginners or more skilled players. With this in mind I set my experienced
R&D team the task of designing a new range of affordable MG amplifiers that truly captured the
essence of the Marshall sound.

Utilising new technologies, some of which were developed for our critically acclaimed AVT range,
the new MG Series raises the standard for what can be expected from a value-for-money range of
guitar amplifiers and defines a new benchmark. For example, the power amp section of your
MG15MSII boasts FDD (Frequency Dependant Damping) – a radical new feature that is exclusive to
Marshall Amplification and accurately mimics the way an all-valve amplifier interacts with a
loudspeaker. As a result of FDD, your new MG15MSII will give you a sound never before thought
possible in such an affordable, non-valve amp.

Like all the amplifiers in my new MG range, the MG15MSII was completely designed and
engineered in the UK and the most rigorous quality control procedures ensure that it meets the
standard of build you have come to expect from all Marshall products.

Whether the MG15MSII is your first ever Marshall or is the latest addition to your arsenal of amps,
the tone, flexibility and feel of this compact, rugged microstack will deliver the goods – from bedroom
to backstage!

I wish you every success with your new Marshall. Welcome to the family…

Yours Sincerely,

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. ALWA YS 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,

connect to the MG15MSII are of a high quality screened type.
These should not exceed 10 metres in length.
Always u

➲ 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.

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

ENGLISH

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’.

3. OD (Overdrive) SELECT switch

Depressing the Overdrive Select Switch will

engage the Overdrive Channel.

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.

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.

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

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 in­between.

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.

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!

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!

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.

HELPFUL HINT: for ‘silent’ recording merely
plug an unconnected jack plug into the
headphone socket and you’ll disconnect the
MG15MSII speaker cabinets.

12. EMULATED HEADPHONES jack

Plug your headphones here for a killer
speaker emulated sound! Doing this mutes
your MG15MSII speaker cabinets for ‘silent’
practice.

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.

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.

Please ensure the amplifier is switched off
and unplugged from the mains electricity
supply before being moved.

1. MAINS INPUT Connector

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.

2. LOUDSPEAKER Outputs

Connect the two loudspeaker cabinets
provided to the speaker outputs using the
speaker leads supplied.

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.
