Vintage Overdrive: Switch to the Boost
channel which is indicated by the red L.E.D.
Again pickups will obviously influence
settings but you will probably find that Gain
settings of around 5 or 6 are quite adequate,
the key however is to increase the Master
Volume level. As our vintage amps didn’t
really have a lot of pre-amp gain, guitarists
used to crank the volume up to be heard
which resulted in the natural classic
Marshall Valve overdrive roar.
Alternatively the Clean Channel with its
volume on maximum gives a very satisfying
vintage type overdrive.
As far as tone settings go we would suggest
that you start with the tone controls set at
about 5 and then adjust to taste from there.
Modern Hi-Gain: Switch to the Boost
channel indicated by the Red L.E.D.
Turn the gain up to full and set the volume
for the desired level. Tone controls are set to
taste, though probably with the Middle
control lower than the Bass and Treble
controls.
The best advice we could really offer is to
simply experiment and above all enjoy the
pure valve tone of your Marshall JTM 60.

Note: To prolong the life of the valves it is
always advisable to switch on the Mains

before switching on the Standby (item 18).
This allows the valves to heat up to full
working temperature before use. On
switching off, the Standby should always be
switched before the Power Switch.
