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 rectifier.
ON/Standby
:
Best to turn the POWER switch on first 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 first. 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 filament 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 flow through
the circuit; thereby gaining up the entire amp natu-
rally and not inducing false preamp gain that creates
fizz 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 fizziness that comes along with crossover distor-
tion. Your mic will notice it before your ears will, so it’s
perfect for use while recording.
