INSTRUCTION MANUAL

Congratulations on purchasing your new Morgan
Amp!
Joe Morgan started designing amplifiers to create
solutions to the problems he was facing as a
guitarist.
The MVP66 is designed with a giant British voice
in mind. Think of the thickest tone that can cut
through even the densest of sound stages and
now imagine being able to turn that raw power
down from overwhelmingly loud to a sound that is
fit for your bedroom and everything in between.
That is the MVP66.
The MVP66 is controlled with Morgan’s “Power
Level” circuitry. This controls the amount of
voltage that we send to the power tubes adjusting
their ability to produce amplification. Dialing the
“Power” control will drop the amplifier’s output
to as little as 1W, and as high as 50! This allows
you to set the overall volume of the amp to the
exact level that you need to keep the sound guy
or spouse happy without having to sacrifice tone.
The MVP66 comes with a bass, treble and middle
tone stack, volume and master volume as well as
the power level control. This allows you to dial in
your perfect sound scape.
This is the amp, as a player, I’ve always wanted.
Big enough to drown out the drummer but quiet
enough to work on any stage. It’s time to
experience the MVP66
The MVP66 also takes pedals very well and loves
Fuzzes, boosts, OD’s, phasers, flangers, tremolos,
wahs, and all types of delay pedals. This amp was
designed to interface with all of your pedals
modern or vintage.
•Incredibly versatile single channel amp
•50- 1w of output power from 2 KT66 tubes
•2x 12ax7s
•Solid state rectifier
•Bass, Treble and Mid controls
•Master Volume
•Volume control
•Power level control
•Custom transformers and capacitors.
PLUGGING IN
We recommend that you start with the power
scaling all of the way up and with the tone
controls in the 12 o’clock position. Set the Gain
level to about 11 o’clock and then increase the
volume control to the level you need.
From here you can gradually bring up the volume
until you reach the desired level of gain. Once you
have this set you can change the Power Level
control to achieve the level of volume you require.
The Gain and Volume controls are interactive.
Your highest levels of clean will be with the
volume control below 3 o’clock. Above 3 o’clock
you are adding gain to the power section of the
amplifier.
Now that you have your gain and volume set
experiment with the bass and treble, and
Midrange controls. Do not be afraid to use
extreme settings on the controls. Cranking the
treble, backing off the mids and bass will get you
into some class A EL84ish tones. Cranking the mids
will increase your gain will make the amp growl
like a great plexi.
We know you will love your new MVP66. If you
have any questions or help don’t hesitate to email

CAUTIO

FRONT PANEL
POWER SWITCH: Turn this ON to power the amplifier. Turn on this switch and the standby switch at the
same time for optimal tube life.
STANDBY SWITCH: Turn ON this switch to put the amp in play mode. This switch should be utilized to
put the amp into a wait state for extended periods of rest. It removes high voltage from your tubes.
Gain: This controls the amount of gain the amp has. The higher the setting the more overdrive to the
preamp tubes you will have. Using this control over the 11:00 mark will result in an overdriven signal. Use
this control in conjunction with the volume control to set your overall drive settings.
Vol: This controls how loud the amp is. The vol control is actually controlling the amount of gain in the
power section of the amplifier. If you are trying to stay as clean as possible stay below 3 o’clock on this
control.
Treb : This control sets the level of high frequencies in the amplifier. This control is interactive with the
Bass and Mid controls.
Mid : The Mid control sets the level of the Mid frequencies. It also behaves to increase the overall level
of the entire tone stack. Setting this control to max will increase the overall gain level of the amplifier.
Bass: The Bass control sets the level of Low frequencies provided by the amp. It is interactive with the
Treb and mid controls.
Power Level : Turning this knob counter clockwise will decrease the voltage available in the output
section of the amplifier. Think of this like a zoom lens for volume. It allows you to go between one watt
and 50 watts. Set your gain level with your Vol control and then lower the Power Level to the volume you
require.
INPUT: This is where you plug your guitar cable into.

REAR PANEL
Speaker Jacks: Your amp is equipped with one 16 ohm and two 8 ohm speaker outputs. The amplifier
should only be operated with a SPEAKER cable connected to the proper impedance output. The two 8
ohm jacks are wired in parallel. If you want to run 2 cabs they need to be 16 ohms and each connected to
the two 8 ohm output jacks
Boost Level: This knob controls the amount of extra boost will be avail when the boost is engaged.
ON: This switch will engage the boost when the footswitch is not being used.
Footswitch: This input is for a single button latching footswitch to engage the boost remotely
MAIN FUSE: Replace with a 2 Amp slo blow fuse for 120V or 1.5 Amp slo blow for 230V. If this fuse blows
the most likely the result of a bad tube. Constant blowing of this fuse (even when using new tubes) is an
indication that something could be seriously wrong with your amp. STOP and call us so we may help you
diagnose.
MAINS INPUT: Plug the supplied IEC power cord here and into a 115v wall outlet to power the amplifier.
