The MF is a Dual Amplifier with Four Modes. 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.
