Attitude, stunning good looks and an incredible
350 Watts of brutal yet toneful power set the Mode Four
apart from all other amps. Add to this an arsenal of great
sounds, a wide range of professional features plus
groundbreaking, state-of-the-art hybrid technology and you
have a Marshall like no other.
MF350 Head
A great many amplifiers have claimedto offer both classic and modern
tones but, in truth, have fallen well short of the mark. The Mode Four
boasts a true ‘Two Amplifiers in One’ design. Not only do AMP1 and
AMP 2have totally separate valve pre-amplifier circuits, eachhousing an
ECC83 valve,the MF350’spoweramp section completely reconfigures
itself depending on the AMP selected. Each AMP type having two
footswitchable modes further enhances flexibility. AMP 1 offers CLEAN
and CRUNCH, while AMP 2 has OD1 and OD2.
AMP 1
AMP 1is the ‘Classic’ side of the Mode Four. Whenever it is selected,the
power amp reconfigures to recreate the unmistakable soundand feel of
our world-renowned 100 Wattvalve power stage. Using this as a sonic
foundation, AMP 1 produces Marshall’s legendary open roar. While
AMP 1’s CLEAN mode produces incrediblydynamic, three-dimensional
clean and bluesycrunch sounds,selectingCRUNCH unleashes the
unbridled aggressionand biteof a 2203, but with levels of gain never
imaginedin 1981 whenthe much-lauded JCM800 series was first
launched.
AMP 2
In terms of sheer gain, AMP 2 takes over from where AMP 1 leaves
off, with OD2 mode offering more gain than any other Marshall
before! Thanks to the Mode Four’s radical design, the player retains
maximum control while searching for the ultimate high-gain signature
sound. Whenever AMP 2 is selected, the Mode Four’s power section
reconfigures itself so it can create the deep, dark-sounding, loose
low-end that has proven so popular with many modern players who
either detune regular 6-strings, or use 7-string or detuned Baritone
guitars.
The Power to Deliver
Due to the unique designand the incredibly highheadroom the
Mode Four’s350 Wattpower stage possesses, AMP 2’simpressively
wide bottom-end not only has the sound and feel of an all-valveamp,
it also doesn’t lose definition at high stage volumes– a problem that
many other similar sounding, all-valve systemssufferfrom.
Fully Loaded for Professional Use
The Mode Four was created with the professional guitarist in mind and
boasts a host of carefully thought out features that have been designed
to give you the ultimate in flexibility and control. These include:
Separate controlsfor Gain, Volume, Bass,Middle and Treble for
AMP 1and AMP 2.
Individually voicedScoop switchesfor AMP 1 and AMP 2.
AMP 2 has a3-way Tone Matrix control, enabling you to dramatically
reconfigure the all-important mids, while leaving the Bass, Middle and
Treble controls fully interactive with each other.

and AMP 2.
Parallel to Series FX Loop withindividual FX Level controls for AMP 1
and AMP 2.
