10 Marshall Amplification Product Catalogue
Launched in 2006, the Vintage Modern Series is a range of
UK manufactured all-valve amplifiers that caters for the
guitarist who likes to primarily control their sound from
playing dynamics and their instruments volume and tone
controls. These amplifiers have 100% mid ’60s to early ’70s
vintage British blues rock tone with the ability to switch to a
hot rod mode to find those ‘modded’ sounds of the harder
rock bands of that era. The KT66 Power Amp section and
power supply are taken from the Super 100 models made
from 1966 to 1968, while the pre-amp has been optimised
to provide greater flexibility in setting the sound to
complement specific instruments and styles and ultimately
achieve your own signature tone. Inherently less aggressive
in the treble region than the later EL34 loaded amps, but
fatter in the low mid and mid region, the sound is instantly
recognisable as classic early Marshall power driven tone!
2466, 2266 & 2266C
The 2466 100 Watt head, 2266 50 Watt head and 2266C 50 Watt 2x12 ”
combo are all-valve single channel amplifiers offering a choice of two
‘dynamic ranges’ selectable by footswitch. The Low range equates to the
performance you would come to expect from a stock vintage Marshall
amplifier in terms of tone and available gain. The High range adds an
extra pre-amp valve into the signal path, facilitating those classic hard
rock tones of the Seventies. Add to this, the ability to optimally interface
with your instrument’s Volume and Tone controls and the experience
translates into a truly expressive and organic feel in performance.
Two ‘frequency selective’ Pre-amp Volumes (Gains) – Body and Detail –
facilitate greater flexibility of tonal shaping for individual guitars and
styles, while the power amplifier is from some of the earliest 100 Watt
Marshall amplifiers to be produced, with KT66 output valves yielding that
substantial fat and smooth tone, four on the 2466 and two on the
2266 & 2266C. A Mid Boost switch on the front panel fattens the tone
even more, while a traditional Marshall tone control circuit enables fine
tuning of your sound.
A Master Volume has been included in order to practically manage the
output levels at all venues. This is implemented after the ‘phase splitter’ in
order to fully exploit maximum pre-amp drive when the master is turned
down low. A Reverb level control mixes the on-board ‘plate’ reverb with
the direct signal to whatever degree the player chooses. The Reverb can
be toggled on and off via the footswitch. A series FX Loop is provided for
those players who wish to use outboard effects to further enhance their
sound. Loop levels of -10dB and +4dB are catered for via a rear panel
switch as well as the option to completely bypass this feature if it’s not
required. Additionally, the 2266C combo comes fitted with two Celestion
G12C 25 Watt Greenback speakers with the facility to use an extension
cabinet if required.
425 Cabinets
The 425A and 425B are the traditional 4 x12 ” Marshall designed cabinets
that accompany this range. They have exactly the same dimensions as
the 1960A/B, but the speakers used in these mono/stereo switchable
100 Watt 4 x12 ”s and in the 2266C combo are the brand new G12C
25 Watt Celestion Greenbacks. These were specifically developed for the
Limited Edition Jimi Hendrix Super100JH stack and are voiced to give
that rich and balanced harmonic timbre that complements vintage tone
and therefore the Vintage Modern Series perfectly.

CABINET SPECIFICATION
“The most responsive amp I’ve ever played, when you crank up the
gain the clarity remains and when the solo boost (Dynamic boost)
kicks in you better run for cover as this beast really cooks!”
Paul Mahon
(The Answer)
“The Vintage Modern is raw, classic tone.
Pure and simple.”
