The JTM-1 is an all-valve, 1-Watt amplifi er
designed and voiced to reproduce the sounds
of the Marshalls of the ’60s but, as Jim has just
mentioned, at a controllable “home friendly” volume.
The ’60s Marshalls were famous for their full
sound, where a well rounded bass is balanced by
a bright airy treble. They were also designed for a
wide range of guitar output levels, so were quite
easy to overdrive at high volumes. The JTM-1
has been designed to provide this distinctive
tonal character at the surprisingly loud level of
one Watt.
The simple control layout of Loudness and Tone
enables you to dial in a great sound with the
minimum of fuss. To add further to the “home
friendly” nature of this amp, whenever the full
1-Watt output proves too loud you can hit the Low
Power button on the rear panel to further drop
the volume – enabling you to crank the loudness
control to get the tone you desire.
The dual-triode ECC82 in the
power amp is confi gured to work
in ‘push pull’, just like the famous
Marshall amps of the period. When combined
with the right level of feedback in the power amp,
this allows for fi ne control over the dynamics,
allowing you to clean up the sound with the guitar
volume, or a lighter, picking touch, and then
“dig in” for some classic ’60s Marshall growl.
The combo is supplied with a 10" 16 Ω Celestion
speaker specially voiced to provide the best
balance between a compact size and a full
sound. Both the combo and the head can drive
an external speaker cabinet of either 16 Ω or
8
Ω
at full power via the corresponding speaker
output jacks on the rear panel. Both amplifi ers
are also very happy driving a full 4x12" cabinet
for the ultimate in mini Marshall tone of the ’60s.

Follow all instructions and heed all warnings.
KEEP THESE INSTRUCTIONS.
Warning:
Before going any further, make sure that your amplifi er is compatible with your electrical supply. If you have any doubt, please seek help from
a qualifi ed technician – your Marshall dealer can help you in this respect.
Mains Input & Fuse:
Your amplifi er is provided with either a detachable mains (power) lead which should be connected to the mains input socket on the rear panel
of the amplifi er or a fi xed mains (power) lead attached to the rear of the amplifi er.
The specifi c mains input voltage rating that your amplifi er has been manufactured for is indicated on the rear panel of the amplifi er.
The correct value and type of mains fuse for valve amplifi ers is specifi ed on the rear panel of the amplifi er.
NEVER attempt to bypass the fuse or fi t one of the incorrect value or type.
Transporting your equipment:
Please ensure that your amplifi er is switched off and unplugged from the mains electricity supply and that all removable cables have been
disconnected from your equipment before attempting to move it.
Important set up information:
1. Make sure that the cabinet(s)/speakers, where appropriate, are connected to the correct impedance LOUDSPEAKER jack(s) on the
rear panel of the amplifi er. See the Speaker Output guides in this handbook, if applicable, for specifi c information regarding impedance
matching. When using an extension cabinet make sure that you are using a proper speaker cable. Never use a screened (shielded) guitar
cable for this purpose.
WARNING! Failure to do any of the above may damage your amplifi er.
2. Ensure that the LOUDNESS controls on the front panel are set to zero.
3. For amplifi ers provided with a detachable mains (power) lead, connect the supplied mains (power) lead into the MAINS INPUT on the rear
panel fi rst and then into an electrical outlet.
4. Plug your guitar into the INPUT jack socket on the front panel.
5. Turn the front panel MAINS switch on and, if a valve amplifi er, wait a couple of minutes before going to point 6.
6. Turn the volumes up to your preferred level and your amp is ready to play.

From “the Guv’nor” Jim Marshall
Congratulations on purchasing one of our Limited Edition
series of 1-Watt heads and combos that celebrate Marshall’s
50th Anniversary. Each one is made in England with pride
and commemorates the distinctive tonal character, features
and iconic appearance of a specifi c decade – ’60s, ’70s, ’80s,
’90s and present day. This one is the fi rst in the series and
represents the sounds of the early Marshalls manufactured in
the company’s fi rst decade of existence, the 1960s...
As you may know, with the help and the designing skills of
Dudley Craven and Ken Bran, the fi rst ever Marshall head was
built in the autumn of 1962. The reason for its creation was to
satisfy the tonal desires of the up-and-coming rock guitarists
at the time. They described to me the exact sound they were
looking for and that was the goal we achieved with that very fi rst
amp – the MK I. During that decade the amp evolved into the
JTM45 Mk II head and also the 1987 Lead version. The 1962
Bluesbreaker 2x12" combo was another of its offspring, born in
the ’60s.
The 1-Watt amp you now own pays homage to both the tone
and look of that all-important fi rst decade and does so at a very
“studio” or “home friendly” volume. The front panel of your amp
is very simple, but extremely effective, and I’m sure that its touch
responsive, easily-overdriven tones will give you countless hours
of playing pleasure.
Welcome to the Marshall family!
Yours Sincerely,
Jim Marshall
