Storing Yours Sounds
When you are satisfied with the sound that you have created, storage is
achieved in the following way. Push the store key (6) once , the LED will
flash (Fig 2). Select the desired patch location using the data entry
control (7). (Pressing the patch or any parameter key will abandon the
store). Push store a second time to complete the store
Memory Lock
A memory lock can be set to keep your data safe. This will disable any
functions that write data to the internal memory i.e Store, Mapping,
Channel & System Exclusive. If the memory is locked an 'L' will appear in
the right of the display when you attempt a store (Fig 3). At this stage the
lock can be toggled on or off by pressing the Channel key.
Sound Selections
There is a definite identifiable character to the "Marshall Sound" throughout the years. largely derived
from the unique qualities of valve power. Our expertise in harnessing valve drive has been fully exploited
in the JMP-1 to recreate the various classic sounds and to generate new tones that will become the classics
of the future. Bearing in mind the variations in guitar types and styles, plus the flexibility of the control
parameters, the following guide gives an indication of each channel's basic sound type.
Clean 1
This is a warm full bodied clean tone, ideal for rich chords, which can be softened for jazz tones or, by
adding gain, will suit clean lead lines with a hint of vintage distortion.
Clean 2
In complete contrast to Clean 1, Clean 2 is bright and glassy with a clear jangling tone. In addition it
contains the unique lively "edge" found only in the early JTM 45 and Super Lead Amps operating at
volumes just below distortion.
OD1
Features the purity of distortion from the golden age of the plexi glass Super Leads. As the gain is
increased you pass through degrees of distortion into a rich higher gain mode, with just the right nuances
for the modern blues rock player. Vintage crunch, modern metal and fat blues lead sounds are all readily
available.
OD2
Tightly focused stunning high gain is what you will find in OD2. Modern and aggressive, smooth and
fluid, the gain levels and singing tone of this channel will give you infinite sustain whilst retaining a pure
toneful quality.
Bass Shift
The Bass Shift option can be switched in or out of any channel selection. When selected it thickens the
bottom end of the sound and tightens the playing feel. On clean selections it adds body and on overdrive
provides the extra low end "throb" so essential for heavy rock sounds.
