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 claimed to 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 AMP 1 and
AMP 2 have totally separate valve pre-amplifier circuits, each housing an
ECC83 valve, the MF350’s power amp 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 1 is the ‘Classic’ side of the Mode Four. Whenever it is selected, the
power amp reconfigures to recreate the unmistakable sound and feel of
our world-renowned 100 Watt valve power stage. Using this as a sonic
foundation, AMP 1 produces Marshall’s legendary open roar. While
AMP 1’s CLEAN mode produces incredibly dynamic, three-dimensional
clean and bluesy crunch sounds, selecting CRUNCH unleashes the
unbridled aggression and bite of a 2203, but with levels of gain never
imagined in 1981 when the 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 design and the incredibly high headroom the
Mode Four’s 350 Watt power stage possesses, AMP 2’s impressively
wide bottom-end not only has the sound and feel of an all-valve amp,
it also doesn’t lose definition at high stage volumes – a problem that
many other similar sounding, all-valve systems suffer from.
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 controls for Gain, Volume, Bass, Middle and Treble for
AMP 1 and AMP 2.
• Individually voiced Scoop switches for AMP 1 and AMP 2.
• AMP 2 has a 3-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.
• Footswitchable, built-in Digital Reverb with separate controls for AMP 1
and AMP 2.
• Parallel to Series FX Loop with individual FX Level controls for AMP 1
and AMP 2.
• Footswitchable Solo Level control that gives a level increase across all
four modes of up to 6dB (i.e. twice the volume).
• Master controls for Resonance, Presence and Volume.
• Tuner Out jack with a front panel Tuner Mute switch for ‘silent’ tuning.
• XLR and 1/4" jack Emulated Line Outputs.
• Load Protection Circuitry.
• 6-way LED Footcontroller supplied.
MF280 & MF400
As you’d expect from the company that invented the ‘stack’, the
Mode Four Series 4x12"s benefit from our forty years of cabinet
expertise. The MF280 (280 Watt) and MF400 (400 Watt) cabinets
are specially engineered to reproduce the balanced mid range
and huge bottom end that are a pre-requisite for modern
rock/metal sounds, and being 3 inches taller than standard 1960
cabinets a Mode Four stack is truly a sight to behold!
We recommend the MF280A (angled) and B (base) for a full
stack and the MF400A or B for a half stack.
