Marshall Amplification has been inextricably linked with valve amplification
since our very beginning in 1962. Products such as the original Bluesbreaker
combos, JTM 45 and Super-Lead heads were all destined to be, and have
become, classics in their own right.
All of these special Marshalls produced their magical tone by driving the guitar
through an all valve pre-amp into a pure valve power-amp. The JCM 600 series
carry on this grand tradition but meet the demands of contemporary guitarists
by providing features such as channel switching, reverb, effects loop and
speaker emulated output.
Using Your JCM 600 Amplifier
Your JCM 600 Valve combo or head is easily capable of producing a wide
range of usable quality tones, from glassy vintage clean, Bluesbreaker type
singing lead and crunchy chord work to full blown modern high gain crush.
What’s more the controls are simple and intuitive to use giving you instant
access to memorable Marshall tones.
Whilst one should always bear in mind that taste in tone is a very subjective
matter, the following suggestions will give you a good starting point for getting
some great sounds from your JCM 600 amplifier.
Clean
Make sure you select the Clean channel which is indicated by the green L.E.D.
The strength and height of your pick-ups will have a great influence on the level
you should set the volume on this channel before overdrive sets in. Generally
speaking the volume control should be set below half way for totally clean
sounds.
The tone network should be set with all three controls at 5 initially, then
adjusted to suit the type of guitar and sound required. Generally single coil
