From the Chairman
I would like to personally thank you for selecting one
of my vintage re-issue amplifiers.
The Marshall reputation has been built upon many
things, but our longevity comes mainly as a result of
the continual relevance of the concepts behind the
design and build of our amplifiers. Added to this are
solid workmanship, reliability, stylish looks, and above
all – great tone. The continual fascination and love that
many guitarists show for our vintage amplification is a
testament to just how relevant and important these
models still are today.
The amp you have just acquired was originally
launched in the 1960s. A time when the face and
sound of popular music was rapidly changing and
players were constantly pushing back the musical
boundaries. Each of these amps was there at the
beginning of this music revolution and all played their
part. From Pete Townshend, Eric Clapton and Jimi
Hendrix, to Jeff Beck and Paul Kossoff, the list of great
‘tone’ players who pioneered the use of the natural
distortion from these amps, reads like a who’s who of
guitar players.
Our re-issues of these models are as faithful as
possible to the originals in terms of looks and tone.
Hand-crafted in the UK these superb units feature
finger-jointed cabinets of birch plywood, hand-welded
chassis’s, hand-wired potentiometers and valve bases
and the highest quality PCBs and componentry.
I would like to wish you every success with your new
amplifier and welcome you to the family of great
players who use the classic Marshall tone.
