OVERVIEW
Introducing the AFD100 – a dual mode, all-valve 100 Watt head that revisits the legendary tones of one of, if not the most important, rock
albums of the last three decades. As well as reproducing what is regarded by many as the “Ultimate Rock Sound”, the AFD100 also contains
some truly awesome features, the first being Marshall’s new electronic power attenuation. This incredible technology allows you to precisely
adjust the maximum power output of the AFD100 without losing any of that sought-after tone. No limited wattage choices to click between and
no compromising your tone, just smooth and consistent power attenuation that is simple to use and makes the AFD100 ideal for stage, studio
and home use.
The Presence, Bass, Middle and Treble controls dictate the overall tone of the AFD100’s highly interactive EQ section, meaning that changes
to one will affect the parameters of the others. This allows for a greater range of tonal possibilities, plus a more fluid and dynamic way of
controlling your sound.
The power amp volume is controlled using the Master, while pre-amp distortion is governed by the Gain. By using these two controls, and
depending on your guitar and playing style, it is possible to dial in both classic high gain Slash tones and biting bright cleans, with everything
in between. Again, the overall output volume of the AFD100 can be governed by the Power control.
The twin modes – #34 and AFD – are based on two of Slash’s legendary tones. The first is taken from Slash’s ‘modded’ JCM800 2203
(complete with stenciled 34 on the side) that he has used since the late ’80s. The second provides an additional gain stage and is of course
based on the infamous ‘Appetite Amp’, widely believed to be a modified 1959 Tremolo from the mid ’70s. Both modes provide a unique,
harmonically rich, natural valve-driven tone, ideal for thick crunchy rhythm and wild soaring solos alike. As with traditional Marshall amplifiers,
the AFD100 provides two sensitivity input options – one high and one low. Either input can be used and is a matter of personal taste.
The AFD100 rear panel features a series Effects Loop, where you can connect any outboard stomp boxes and/or rack equipment you may
have. The Return Level control allows you to dial in the exact amount of Effects Loop signal you want and can even be used as a second
master volume when left unconnected, providing a boost of up to +10dB or attenuating the signal to a lower volume. A valve fault indicator
and self-biasing circuitry have been included as well, ensuring that any maintenance can be carried out quickly and that the amplifier’s bias is
always correctly configured. You can also choose to have other types of popular octal pentode or tetrode power valves installed (see Rear
Panel features, section 3). This work should always be undertaken by a qualified engineer – ask your local Marshall dealer for more
information. The included two-way footswitch connects via the rear panel also, allowing for quick #34/AFD mode changes and Effects Loop
on/off toggling.
Cosmetically, the AFD100 blends key characteristics of both an old-school ‘seventies’ style head and a mighty JCM800. The modern silver
panel and matching knobs also pay homage to the 2555 Silver Jubilees on which Marshall’s inaugural Slash Signature amplifier was based.
Classic black Levant vinyl covering, a small vintage script logo and white piping complete the unique livery of this incredible tone machine.
We recommend that you read through the information in this owners manual carefully before powering up your AFD100 to ensure you get
the best out of your new amplifier.

FROM JIM MARSHALL
I would like to thank you personally for choosing this limited AFD100 Slash
Signature Series Amplifier – our tribute to one of the greatest rock tones
ever recorded and one of the most influential guitarists of the past
25 years.
I have known Slash since the early ’90s and I have rarely met a more
humble rock star. I remember when we launched the JCM Slash
Signature Amplifier back in 1996, the first signature Marshall amp ever,
Slash was utterly flattered by the concept and kept asking “Why me?” My
reason was, and still is, that in addition to being a truly great guitarist,
Slash personifies the spirit of rock ’n ’roll. That Silver Jubilee re-issue
proved to be a huge success and has paved the way for numerous
Marshall Signature Series amplifiers ever since. So, when Slash came to
us with the idea of recreating his fabled
Appetite For Destruction
tone,
I immediately put the challenge to the Marshall team. This would be no
easy task as, unlike most signature models, there was no original amplifier
to examine and replicate. Our Engineers had to rely on studying the
original recordings and information from Slash himself to find that elusive
sound. Yet, after countless hours of research and development, the first
prototypes were ready for the ultimate test – a world tour! I’m pleased to
say this latest addition to the Marshall Signature range is now a
permanent fixture in Slash’s rig.
This project represented another first for Marshall, as every stage of
development was made public through the AFD100.com website. From
initial research, including the intriguing AFD amplifier back-story, to
prototypes and full production models, every move was documented and
followed by thousands of fans around the globe. Visitors to the site were
also treated to engineer blogs, news updates and even behind-the-scenes
video footage, as well as being able to post comments and ask questions
directly to the Marshall team. It was a great experience, one which I’m
sure we’ll use again.
I would like to take this opportunity to wish you every success with your
new AFD100 Slash Signature Series Amplifier and I hope it brings you
many years of playing pleasure.
Welcome to the Marshall family.
Yours Sincerely
Dr Jim Marshall OBE
