MAINS INPUT & FUSE:
The specific mains input voltage rating
that your amplifier has been manufactured
for is indicated on the rear panel of the
amplifier. MG50FX: Your amplifier is
provided with a detachable mains (power)
lead, which should be connected to the
MAINS INPUT socket on the rear panel of
the amplifier. The correct value and type
of mains fuse is specified on the rear panel
of each amplifier.
NEVER attempt to bypass the fuse or fit one
of the incorrect value or type.
TRANSPORTING YOUR EQUIPMENT:
Please ensure that your amplifier is
switched off, unplugged from the mains
electricity supply and that all removable
cables have been disconnected from your
equipment before attempting to move it.
ENGLISH
IMPORTANT SET UP INFORMATION:
WARNING:
Failure to select the correct impedance
may damage your amplifier.
If connecting a speaker cabinet make sure
that you use a proper speaker cable. Never
use a screened (shielded) guitar cable for
this purpose.
1. Ensure that the MAINS (power)
switch is set to the OFF position.
2. Connect the supplied mains (power)
lead into the MAINS INPUT first and
then into the mains electricity supply.
3. Ensure that the VOLUME controls on
the front panel are set to zero.
4. Plug your guitar into an INPUT jack
socket.
5. Turn the front panel MAINS switch to
the ON position.
6. Turn the VOLUME up to your
preferred level and your amplifier is
ready to play.

ENGLISH
MG15FX & MG30FX OVERVIEW
(13) which is not storable, will now not
match the actual settings of the amplifier.
All front panel switches will automatically
update.
CHANNEL SELECTION
The amplifier has 4 channels - Clean,
Crunch, OD-1 & OD-2.
Pressing the Clean/Crunch switch (3)
selects between the Clean (Green Light)
and Crunch (Red Light) channels.
Altering a control will cause the associated
parameter to jump to the current physical
position of that control.
Pressing the OD-1/OD-2 switch (5)
selects between the OD-1 (Green Light)
and OD-2 (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
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
digital effects, Reverb (Studio or Spring)
and one of five FX (Chorus, Phaser,
Flanger, Delay or Octave).
REVERB
The Reverb control (8) sets the amount
of signal sent to either one of the two
ENGLISH
reverb options - Studio or Spring 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.
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.
FX
The FX control is essentially split into five
segments and selects the type of FX and
adjusts its associated settings - except
in the case of Octave which has a simple
setting. 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
FX Off
Chorus
Speed increases and depth is reduced as knob is
turned clockwise.
Phaser
Speed increases as knob is turned clockwise.
Flanger
Speed increases, feedback and depth are
reduced as knob is turned clockwise.
Delay
Delay level is increased as knob turned
clockwise.
Octave
When the FX control is turned fully clockwise
the Octave effect is engaged – producing a
simultaneous note a full octave lower than the
one being played.
TAP TEMPO
The Tap Tempo switch (10) is used for the
Delay effect only.
HEADPHONES
The 3.5mm Headphone socket (16)
allows the connection of a pair of
headphones. When a jack is inserted into
the headphone 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.
RESTORING SETTINGS - WARNING ALL AMP
& FOOTCONTROLLER ALLOCATIONS 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-1/OD-2 (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 allocations, replacing them
with the factory presets.
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.

sound of a reverse or backwards delay –
usually created in a studio by reversing the
tape or track (i.e. playing it backwards).

The Tap Tempo switch (13) is used for the
Delay effect only.
Additionally the Headphone socket (18)
can also be used as a Line Out to send
the signal to an external equipment e.g.
A computer, digital recorder or mixer.
When a jack is inserted into the socket the
unit’s speaker is muted providing ‘silent
recording’. The unit’s output can then
be monitored directly from the external
equipment used.
DAMPING
The Damping switch (17) selects between
the two modes of power amp damping.
When Damping is off (LED off), the
power amp response resembles the feel
of a classic power amp with emphasised
middle and limited bass and treble.
Switching Damping on (LED on) will boost
the speaker resonances both in the bass
