From Jim Marshall
I would personally like to congratulate you on your purchase of this next-generation Marshall MG amplifier.
As a musician myself, I fully understand what it takes to perform live in a band situation. In addition to talent, dedication and a lot of hard work, you also need equipment that does exactly what you ask of it. Over the years I have witnessed many advances in amplifier technology and I wanted this MG series to take full advantage of such innovations. These solid-state amplifiers had to meet the tonal expectations of the modern guitarist whilst also incorporating new and exciting digital technology. With this goal firmly in mind, I set my experienced R&D team the task of designing a new range of affordable MG amplifiers that would not only produce the tone you’re looking for, but also offer an intuitive and totally programmable way of customising, storing and accessing your favourite Marshall tones and features.
Like all the amplifiers in the new MG range, state-of-the-art manufacturing and stringent quality control procedures ensure that these amplifiers meet the high standard of build you have come to expect from all Marshall products.
Whether this is your first ever Marshall, or is the latest addition to your arsenal of amps, the tone, flexibility and feel of these compact, rugged units is guaranteed to deliver the goods – from bedroom, to backstage, to on stage!
I wish you every success with your new Marshall. Welcome to the family...
Yours Sincerely,
Dr. Jim Marshall OBE

MG15FX & MG30FX Overview
Channel Selection
The amplifier has 4 channels - Clean, Crunch, OD1 & OD2.
Pressing the Clean/Crunch switch (3) selects between the Clean (Green Light) and Crunch (Red Light) channels.
Pressing the OD switch (5) selects between the OD1 (Green Light) and OD2 (Red Light) channels.
When moving from an OD channel to a Clean/Crunch channel, the unit remembers the last channel you were in before leaving. E.g. If you have moved from the Crunch Channel to an OD channel and you press the Clean/Crunch switch (3), the amplifier will revert back to the Crunch channel - rather than starting again in the Clean channel.
Modes
The amplifier operates in two modes - Preset and Manual.
To change between these two modes, you must hold the Tap switch (10) down for at least two seconds. When in manual mode the Store switch (12) lights red and the selected channel light (3 or 5) will start to flash.
The amplifier will remember the last mode it was in after power off and revert to it the next time it is powered on.
Preset
This is the factory default operation of the amplifier.
In Preset mode the position of all controls except Master Volume (13) are stored within each channel. Each channel should be considered a preset.
Selecting a channel automatically recalls the settings stored within the channel. Note: The physical position of the front panel controls, except Master Volume (13) which is not storable, will now not match the actual settings of the amplifier. All front panel switches will automatically update.
Altering a control will cause the associated parameter to jump to the current physical position of that control.
When a control is altered the selected channel light (3 or 5) will start to flash indicating that the current preset has been altered.
To store the updated settings, push the Store switch (12).
If you select another channel without pressing Store (12) then any altered settings will be lost as the new channel and its settings are recalled.
Manual
In manual mode the amp’s settings always match the physical positions of the controls.
Changing channel only changes the channel, NO presets are recalled, NO other controls are altered.
Pressing Store (12) will store the current settings into the selected channel. These can then be recalled when using the unit in Preset mode.
When channel settings have been stored the current channel light (3 or 5) will stop flashing indicating the preset has been saved.
Reverb & FX
The amplifier provides two simultaneous effects, Reverb and one of four FXs (Chorus, Phaser, Flanger or Delay)
Reverb
The Reverb control (8) sets the amount of signal sent to the reverb section - allowing the reverb to spill between channels as different presets are recalled. When the Reverb control (8) is set to ‘0’ the reverb is switched off, the status of the reverb is also indicated on the optional footcontroller.
FX
The FX control is split into four segments and selects the type of FX and adjusts its associated settings. When the FX control is set to ‘0’ the FX are switched off, the status of the FX is also indicated on the optional footcontroller.
0 Chorus
Phaser
Flanger
Delay
Tap Tempo
The Tap Tempo switch (10) is used for the Delay effect only.
The Tap Tempo switch matches the delay time to the time between two presses.
The Tap Tempo LED flashes red at the selected/recalled delay time.
The number of repeats is reduced as the delay time decreases.
If you change from a channel with delay to one without delay the effect will spill between channels.
If you change from a channel with delay to a channel with delay set to a different delay time the delay effect will not spill between channels.
MP3 / Line In
The 3.5mm MP3 / Line In socket (14) allows the connection of an external audio source e.g. MP3 or CD player.
Headphones
The 3.5mm Headphones socket (16) allows the connection of a pair of headphones. When a jack is inserted into the headphones socket the unit’s speaker is muted.
Power
The Power switch (17) turns the amplifier on and off. If current settings have not been stored they will be lost.
FX Off Speed increases and depth is reduced as knob is turned clockwise. Speed increases as knob is turned clockwise. Speed increases, feedback and depth are reduced as knob is turned clockwise. Delay level is increased as knob turned clockwise.
Restoring Settings - WARNING ALLAMP & FOOTCONTROLLER SETTINGS WILL BE LOST
To restore the unit to factory settings (see handbook rear cover) you must hold the Store switch (12) while powering on the unit. The Clean/Crunch (3) and OD (5) lights will light orange. You can then release the Store switch (12).
Resetting the amplifier will erase all user Channel presets and all user Footcontroller settings, replacing them with the factory presets.
