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 Morgan PR12 combines all of the mods I have
ever been asked to do on the princeton reverb
circuit. This 12watt 6v6 amplifier will surprise you
at how loud and punchy it is for its small size. This
is the perfect gigging amp for small venues and for
church or home use.
The PR12 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
 12-watt 2X 6V6 Power Tubes
 3x 12ax7s
 GZ24 tube rectifier
 Bass and Treble controls
 Volume control
 Reverb
 Dwell control
 Custom transformers and capacitors.
PLUGGING IN
We recommend that you start with the tone
controls in the 12 o’clock position. Set the Vol
level to about 11 o’clock, reverb should be set to
taste. The dwell completely at clockwise is a
standard fender style reverb.
.
We know you will love your new PR12. If you have
any questions or help don’t hesitate to email us at

INSTRUCTIONS
Please keep this instruction manual for future
reference and for the duration of owning this
Morgan Amplifier. Please carefully read and
understand the instructions inside this user’s
manual before attempting to operate your new
amp. This instruction manual includes essential
safety information regarding the use and
maintenance of the amplifier. Take special care to
heed all warning symbols and signs inside this
manual and those printed on the amplifier itself.
WARNING!
TO PREVENT FIRE OR SHOCK HAZARD, DO NOT
EXPOSE THE AMPLIFIER TO WATER OR MOISTURE.
DO NOT OPERATE NEAR ANY WATER SOURCE
WHAT’S THE MEANING OF THIS?
The lightning flash with an arrow triangular
symbol is intended to alert the user to the
presence of non-insulated “dangerous voltage”
within the products enclosure, and may be of
sufficient magnitude to constitute a risk of electric
shock
WHAT’S THE MEANING OF THIS?
The exclamation point triangular symbol is
intended to alert the user to the presence of
important operating and maintenance (servicing)
instructions in the user manual accompanying this
amplifier!
1. Read Instructions – All the safety and operating

your home, consult your product dealer or local
power company.
10. Grounding or Polarization
– This product may be equipped with a polarized
alternation-current line plug (a plug having one
blade wider than the other). This plug will fit into
the power outlet only one way. This is a safety
feature. If you are unable to insert the plug fully
into the outlet, try reversing the plug. If the plug
should still fail to fit, contact your electrician to
replace your obsolete outlet. Do not defeat the
safety purpose of the polarized plug.
11. Power-Cord Protection
– Power-supply cords should be routed so that
they are not likely to be walked on or pinched by
items placed upon or against them, paying
particular attention to the cord in correspondence
of plugs, convenience receptacles, and the point
where they exit from the amplifier.
12. Cleaning – The amplifier should be cleaned
only as recommended by the manufacturer. Clean
by wiping with a cloth slightly damp with water.
Avoid getting water inside the amplifier.
14. Non-use Periods – The power cord of the
amplifier should be unplugged from the outlet
when left unused for a long period of time.
15. Object and Liquid Entry
– Care should be taken so that objects do not fall
and liquids are not spilled into the enclosure
through openings.
16. Damage Requiring Service
– The amplifier should be serviced by qualified
service personnel when:
A. The power-supply cord or the plug has been
damaged; or
B. Objects have fallen, or liquid has been spilled
into the amplifier; or
C. The amplifier has been exposed to rain; or
D. The amplifier does not appear to operate
normally or exhibits a marked change in
performance; or
E. The amplifier has been dropped, or the
enclosure damaged.
F. The amplifier needs tube replacement or
biasing
17. Servicing – The user should not attempt any
service to the amplifier beyond that described in
the operating instructions.
All other servicing should be referred to qualified
service personnel.
18. Ventilation – Slots and openings in the cabinet
are provided for ventilation and to ensure reliable
operation of the product and to protect it from
overheating, and these openings must not be
blocked or covered. The openings should never be
blocked by placing the product on a bed, sofa, rug,
or other similar surface. This product should not
be placed in a built- in installation such as a
bookcase or rack.
19. Attachments – do not use attachments not
recommended by the product manufacturer as
they may cause hazards.
20. Accessories – Do not place this product on an
unstable cart, stand, tripod, bracket, or table. The
product may fall, causing serious injury to a child
or adult, and serious damage to the product. Use
only with a cart, stand, tripod, bracket, or table
recommended by the manufacturer, or sold with
the product.
21. Lightning – For added protection for this
product before a lightning storm, or when it is left
unattended and unused for long periods of time,
unplug it from the wall outlet. This will prevent
damage to the product due to lightning and power
line surges.
22. Replacement Parts – When replacement parts
are required, be sure the service technician has
used replacement parts specified by the
manufacturer or have the same characteristics as
the original part. Unauthorized substitutions may
result in fire, electric shock, or other hazards.

or repairs to this product, ask the service
technician to perform safety checks to determine
that the product is in proper operating condition.

of fuse as indicated on the rear panel. Note the
proper rating fuse is determined by the AC line
voltage in the country this unit is being operated.
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.
Vol: 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.
Treb : This control sets the level of high frequencies in the amplifier. This control is interactive with the
Bass control.
Bass: The Bass control sets the level of Low frequencies provided by the amp. It is inter active with the
Treb control.
REVERB : This controls the amount of reverberated signal that is added to the dry signal.
Dwell: Controls the amount of back splash that is added to the reverb signal. All the way up is the classic
setting.
INPUT: This is where you plug your guitar cable in.
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
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.
Reverb FS: This jack accepts any latching footswitch to control the reverb on/off.
MAINS INPUT: Plug the supplied IEC power cord here and into a 115v wall outlet to power the amplifier.
