Tupelo Guitar Amplier
Congratulations on your purchase of the Tupelo!
The Tupelo is a breakthrough amplier rooted in some
lost designs from the early ‘60s best designer, only
based on a 6V6 power section. Its unique circuitry
creates a platform that reveals the true character of the
power tubes to a surprising level. The 6V6 power sec-
tion colors the character of the front end to sound like
outstanding examples of American circuitry from the
late ‘50s through the mid-sixties while at the same time
removing all the bad behaviors of those old amps. The
Tupelo is a must for players whose ears are tuned to
American circuits and sounds. Equally comfortable in
every music genre, the hot-rodded Tupelo is a super-
versatile cousin to the 65amps Lil’ Elvis with more
power, an astonishing vocabulary, touch sensitivity and
harmonic richness. It is loaded with 65amp’s “Master
Voltage” circuitry to make the Tupelo comfortable at
any volume, from bedroom to coffee house to small
clubs to the studio. The Tupelo also features a passive
FX Loop, 2 speaker outs, 65amp’s unique bias tremolo,
and of course... rich tone for days!

CAUTION - FOR U.S. OPERATION, SET AC VOLTAGE SELECTOR FOR 120 VOLTS ONLY!

65amps TUPELO FRONT PANEL
Tubes:
The Tupelo tube complement consists of six tubes:
three 12AX7 preamp tubes, two 6V6 output tubes,
and a solid state rectier.
ON/Standby:
Best to turn the POWER switch on rst before the
Standby and wait about 10 seconds before turning
Standby on. This will prolong tube life. When turning
the amp off, turn POWER switch off rst. This allows
the power to drain out of the amp circuit. You can
turn off the Standby switch later before turning the
amp back on.
Master Voltage:
Our master voltage emulates the tonal response of
a big amp only at low volumes. The “Master Volt-
age”™ knob reduces the B+ voltage and output in
the amp in a unique way that keeps the internal tube
relationships perfect while keeping the lament volt-
age up. After seeing all other power schemes’ short-
comings, we’ve come at this from a different angle
and we’re very pleased with the results. You can dial
this amp down to 3 watts output WITHOUT losing
tone, feel, vocabulary, authority, etc.
Speed & Intensity:
These two knobs control the speed and depth of the
Bias Tremolo, which modulates the level both up and
down but, unlike traditional designs, also incorpo-
rates some clever circuitry that always allows the
attack of a new chord or note to pass through at its
normal level, regardless of where the tremolo oscilla-
tor is in its cycle.
Bump Control:
The Bump™ control is a much more effective alter-
native to traditional channel switching. The Bump™
allows the user gain-up and re-slope the amp’s tone
stack allowing much more midrange to ow through
the circuit; thereby gaining up the entire amp natu-
rally and not inducing false preamp gain that creates
zz and buzz. The end result is the effect of having
two amps in one.
Tone controls:
The Tone control is a passive cut-style. We recom-
mend starting at “10” and backing off. With brighter
single-coil guitars, the mid’s will focus really well
with the TONE set back around “5 to 8”.
Smooth Switch:
The Smooth switch removes crossover distortion for a
smoother tone. This is most useful at higher volumes.
Flip it on when the amp is revved up and it removes
the zziness that comes along with crossover distor-
tion. Your mic will notice it before your ears will, so it’s
perfect for use while recording.

FX Loop - The passive effects loop comes out on a
pair of jacks, allowing the user’s own effects to be
added after the preamp stage.
CHANNEL FTSW - This is allows you to change
channels.
SPEAKER OUTPUTS - Two speaker outputs in
parallel.
IMPEDANCE - All 65 212-Combos and Extension
Cabinets are wired for 16-ohms (two 8-ohm speak-
ers in series). If using two 16-ohm cabinets, set
IMPEDANCE to 8-ohms. Always be sure to match the
impedance of this amplier with the impedance of
the speaker cabinet you are using.
H.T. (High Tension) FUSE - (500mA Slo-Blo) This
fuse is in line with the DC voltage in the amp. When
the H.T. FUSE blows, it is typically a sign of a bad
power tube.
A.C. FUSE - (2A/250V Slo Blo) This fuse is connect-
ed to the AC primary side of the Power Transformer.
CAUTION - Never use a fuse with a higher amper-
age rating.

IMPORTANT: We recommend a qualied technician
for retubing. All tubes use the same size socket, but
have very different wiring congurations and volt-
ages. Placing the wrong tube in the wrong socket
can cause damage
to the amplier and tube.
PLEASE READ THE FOLLOWING WARNINGS AND
USER ADVICE!
• Always make sure the AC Voltage Selector is set for
the proper voltage (120 volts in the U.S.) before turn-
ing on the amplier!
• Always make sure the amplier is grounded!
(3-prong connector - no ground lifts).
• Use only a high quality grounded 3-prong AC
power cable with this unit. Always look for breaks or
exposed wire and replace if defective.
• Never remove the chassis from the cabinet! The
amplier will store high voltages long after the amp
has been turned off and disconnected from the AC.
Changing tubes does not require any internal adjust-
ments. Refer all service to a qualied technician.
• Do not expose to excessive humidity, direct sun-
light or extreme high or low temperatures. Be certain
there is adequate ventilation around the amplier.
Never expose to liquids or excessive dust.
