MARSHALL AMPLIFIER HISTORY
MST modelling recreates the tonal and sonic characteristics of some of the most successful
and respected amplifier preamps from the past fifty plus years.
JTM45™
The JTM45 was the first Marshall amplifier. It was made in 1962 by Jim Marshall and his
small team of engineers in a workshop at his music store in Hanwell, London. This 30 Watt
two channel amplifier began a revolution that changed forever the sound of rock and
blues music. The JTM45 is still made today as part of the Vintage Re-Issue™ Series and
Handwired™ Series.
1962 Bluesbreaker™
The 1962 Bluesbreaker was the first combo made by Marshall. Launched in 1965, it had
two 12" speakers with an output of 30 Watts. The 1962 was famously used by Eric Clapton
on the influential blues album 'John Mayall's Bluesbreakers' in 1966 – hence the 1962's
'Bluesbreaker' nickname. The 1962 Bluesbreaker is still made today as part of the Vintage
Re-Issue Series™ and Handwired™ Series.
1959™ Plexi™
To the minds and ears of many, the 100 Watt Super Lead heads of the mid to late 1960s are
the holy grail of great rock tone. Being non-master-volume, when cranked, the 1959 power
valves overdrive producing highly responsive, harmonically rich tones. The 1959 amplifier
is still made today as part of the Vintage Re-Issue Series™ and Handwired™ Series.
JCM800 2203™
The 2203 is one of the most important amplifiers Marshall has ever made. It evolved in the
'70s from the JMP and 1959 Plexi heads. In the '80s the 2203 became the JCM800 2203
we know today: a straightforward single channel amplifier that was favoured by the heavy
metal scene that dominated much of that decade. Its popularity remained well into the '90s
with the emergence of Grunge and Britpop, and it's still revered today and is considered
the benchmark by which modern all metal amplifiers are measured.
JCM2555™ Silver Jubilee™
The 25/50 Silver Jubilee Series was created in 1987 to celebrate the 25th anniversary of
the founding of Marshall Amplification and 50 years of Jim Marshall being in the music
business. Based on the JCM800 2203 and 2204™ Master Volume models, Silver Jubilee
amplifiers had a special preamp circuit that featured three gain 'modes' which were Clean,
Rhythm Clip and a switchable Lead Channel. The 2555 was the 100 Watt head in the
Jubilee series, which was a limited edition. By popular demand the JCM2555 was re-issued
as the 2555X™ in 2015.
JCM2000™ DSL100™
Launched in 1997, the JCM2000 Dual Super Lead's 'dual mode' design meant that guitarists
could choose either a Clean or Crunch tone from the Classic Gain Channel, whilst the
Ultra Gain Channel provided two lead sounds: Lead 1 & Lead 2. This tonal versatility was
aided by the Deep and Tone Shift features. It is the JCM2000 DSL100's tonal range and
versatility that made it massively popular in its day, so much so, that its legacy lives on in
the current DSL Series.

JVM410H™
When the JVM410H launched in 2006 it caused quite a stir. This 100 Watt head is an all-
valve tonal monster that has four channels, each with three modes: Green, Orange and
Red, offering guitarists a range of 12 unique tones. Each mode reconfigures the channel
gain stages in order to develop different amounts of gain and tone. The JVM410H's vast
tonal spectrum makes it the most versatile amplifier Marshall has ever made, used by many
professional players.

POWER AMPLIFIERS

MST modelling recreates four classic and vintage valve power output topologies. A valve
power stage is a vital part of an all-valve amplifier's sound and its tonal character.
SPEAKER CABINETS
Marshall speaker cabinets are perhaps as famous as Marshall amplifiers. The iconic 4 x 12"
design has changed little since Jim Marshall designed the first one in 1965. Since then the
Marshall 4 x 12" has become the touchstone for all other speaker cabinets. MST modelling
recreates the sonic characteristics of eight classic Marshall speaker cabinets, including a
variety of 4 x 12", 2 x 12" & 1 x 12" speaker configurations. Marshall speaker cabinets differ
not only in their speaker configurations, but in the speakers that they use, how they are
wired and the size of the cabinet.
