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
overdrive roar. Alternatively the Normal 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. The selection of tone settings for
single coil or humbucking pickups will follow the same general pattern as for the
clean sound.
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 particularly to maintain the definition when using humbucking
pickups.
The best advice we could really offer is to simply experiment and above all enjoy
the pure valve tone of your Marshall JTM amplifier.
