The Marshall 1959 Super Lead Plexi head and the JCM 800 Master Volume 2203 are
recognised the world over as benchmarks in tone, feel, musical power and sheer size of sound.
Imagine then, an amp which is like two footswitchable 1959 Super Leads in one, with the
addition of reverb plus extra gain to take you into 2203 territory and beyond. If this sounds like
a dream, it is no longer - now that the JCM 2000 Dual Super Lead range is here.
The 100 Watt DSL 100 and 50 Watt DSL 50 Dual Super Lead heads feature two
footswitchable channels, Classic Gain / Channel A and Ultra Gain / Channel B. As the names
imply, each channel has a very different character, with Classic Gain / Channel A taking you
from a clean to crunch 1959 and then, via a mode switch, up to a 2203 style brute. Ultra Gain /
Channel B takes you from a hot rodded 2203, via a mode switch, to a higher gain response with
the addition of mid-boost. Each channel also has its own individual Reverb level.
The amps also feature a Deep Switch and Tone Shift which are common to both channels.
The Deep Switch adds a resonant bass boost to your sound without muddying it up, while the
Tone Shift selector shifts out the mid frequencies making the amp ideal for brutal metal tones,
especially when combined with high gain settings.
Their all round versatility and sheer size of sound make the DSL 100 and DSL 50 superb
performance tools for today’s most demanding playing situations and you can rest assured they
are packed full of the famed Marshall TONE.
Please read this handbook carefully before plugging in.
