Product Description In modern rock guitar, there has been a dramatic increase in the demand for an amplifier with the following attributes – incredible high gain, dramatically expanded headroom and a low-end response capable of comfortably accommodating detuned 6-string, 7-string and baritone guitars.
With these requirements in mind, Marshall's R&D team set about designing such a product. The outcome of their labor is the Mode Four MF350, a 350 Watt head, and four Celestion-loaded, 4x12 in. cabinets that are actually larger in size than the regular Marshall 1960 4x12 in. cabinets (the industry standard). In addition to delivering aggressive, bottom heavy, modern, high-gain sounds, Marshall also wanted the Mode Four to offer great clean tones as well as the myriad of overdriven sounds that have made Marshall famous.
To achieve such tonal flexibility, the MF350 boasts a "two amplifiers in one" design. These two amps, named AMP 1 and AMP 2, both feature two footswitchable modes. This gives the player four mode options – hence the head’s name. To be precise: AMP 1 is the "classic" amp and its two modes are CLEAN and CRUNCH, while AMP 2 is the high-gain, "modern" amp with OD1 and OD2 as its two modes. AMP 1 and AMP 2 each have their own totally independent, valve pre-amp section and the Mode Four's proprietary power stage automatically reconfigures itself depending on whether AMP 1 or AMP 2 has been selected. Footswitch included.
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 1/4 in. jack EMULATED LINE OUTPUTS.
Load Protection circuitry
6-way LED footcontroller supplied.
350 Watt RMS Output Early technical research ruled out many options for achieving the all-important, extended low-end response required of the Mode Four. What became apparent from the start was that the unusually low damping characteristics needed to give the required sound and feel had its own particular drawbacks. Marshall's engineers found that at the onset of power amplifier clipping, the already low damping characteristic is reduced still further. This results in uncontrolled movement of the speaker cone (i.e. the power amplifier starts to "woof" out and notes become indiscernible).
With this information at hand, R&D looked at various options to combat this limiting factor. The MODE FOUR's unique power amplifier topology allows for extremely high headroom (i.e. power to be delivered before clipping) in conjunction with a low damping characteristic. This enables the MODE FOUR to deliver the increased bass resonance associated with low damping, without the drawbacks of other designs.
