Marshall MF350H
Dual Amplifier with Four Modes
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, including an ECC83 valve each, but the MODE FOUR also completely reconfigures its power amplifier section depending on the AMP type selected.

The MODE FOUR’s flexibility is further enhanced by each of the two AMP types having two footswitchable modes. AMP1 offers Clean and Crunch modes, while AMP2 has OD1 and OD2.
AMP 1
AMP 1 is effectively the ’Classic’ side of the MODE FOUR. Whenever it is selected, the power amplifier configures to recreate the unmistakable sound and feel of our world renowned 100 Watt valve power stage. By using this as a sonic foundation, AMP1 produces the unmistakeable Marshall power amp roar.

While AMP 1’s Clean mode produces incredibly dynamic, three-dimensional clean and bluesy crunch sounds, its Crunch mode unleashes the un-bridled aggression and bite of the JCM800 Series, but with levels of gain never imagined in 1981, when this much-lauded series was first launched.

AMP 2
In terms of sheer gain, AMP 2 takes over from where AMP1 leaves off, with OD2 mode offering more Gain than any other Marshall before it, and thanks to the MODE FOUR’s radical design, the player retains maximum control while searching for the ultimate high-gain signature sound.

The Power to Deliver
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 proved itself to be so popular with many modern players who either detune regular six-strings, or use 7-string or detuned Baritone guitars.

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
From the very start, the MODE FOUR was created with the professional guitarist in mind. To this end it boasts a host of carefully thought out features that have been designed to give you, the player, the ultimate in professional flexibility and control. These include:

Separate controls for GAIN, VOLUME, BASS, MIDDLE and TREBLE for each AMP.

Individually voiced SCOOP switches for each AMP.

AMP 2 has a three-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 REVERB 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 between songs.

XLR and ¼" jack EMULATED LINE OUTPUTS.

LOAD PROTECTION CIRCUITRY.

6-way LED footcontroller supplied.

MF280A Angled 4X12 280 Watt 16Ohm Cabinet

The MF280 (280W) and MF400 (400W) cabinets are specially engineered to reproduce the balanced mid range and huge bottom end that are a pre-requisite for extreme hard rock and nu-metal sounds, these cabinets feature:

- Sonically optimised Celestion loudspeaker designs
- Pro-gauge internal wiring
- Increased internal volume
- Metal logo and piping

In keeping with all legendary Marshall cabinets the MF 4x12" cabinets are not only ready for the sonic demands of a high performance head like the MF350, but also the extreme physical abuse they may receive on the road.

We recommend the MF280A (angled) and B (base) for full stack operation and the MF400A or B for half stack operation.

Full Stack versus Half Stack
The MODE FOUR cabinets can be used either as a full stack (two cabinets) or half stack (one cabinet) configuration. The rig you choose is a matter of personal taste and as always when it comes to sound we recommend you try both to see which suits your style best. Below is a guide to the major attributes of each:

Full Stack:
Enhanced on stage spread.
More ’cut through’ due to accentuated treble and high mids.
Iconic stage presence.

Half Stack:
More controllable spread of sound on stage (especially base type)
Convenient and portable.



Half Stack Options

Whether you choose an angled or base half stack configuration is a personal choice between the different tonal qualities of each set up.

The MF400A (angled) is, in keeping with other angled 4x12" cabinets, tonally more aggressive than the base option. The angled cabinet is the usual choice for those who want a more prominent upper mid and treble response that really cuts through in a live situation.

Alternatively, the MF400B (base) delivers a more even mid range with less spread of the aggressive treble response. Marshall 4x12" base cabinets are more often used by professionals as they have a more focused bottom end and a smoother mid range and treble response. They are often easier to deal with in terms of sound reinforcement and monitoring in a live situation.
