From the Chairman

I would like to personally thank you for selecting this
re-issue of my all-valve, JCM800 2203, 100 Watt, Master
Volume head. My company’s reputation and longevity
have been built on a great many things – groundbreaking
designs, skilled workmanship, reliability, flexibility, stylish
looks and, above all else, great tone and feel. The
continual fascination and love that many current guitarists
show for our vintage amplification products is a testament
to just how relevant and important such models are to this
very day.

The amplifier you have just acquired is a re-issue of the
JCM800 2203, 100 Watt head that was originally
launched in March of 1981 and proved incredibly popular
with rock guitarists throughout the ‘80s. Although my
JCM900 Series replaced the entire JCM800 range in
1991, the 2203 has remained a firm favourite with
countless players – hence my decision to start making it
again.

Our re-issue of the JCM800 2203 is totally faithful to
the original in terms of looks, tone and feel. At the request
of many 2203 fanatics it also boasts the addition of a
Series Effects Loop – a feature which makes it totally at
home in the modern performance arena.

I would like to wish you every success with your new
amplifier and welcome you to the large and ever
increasing family of players who plug into Marshall
products.
