SPEAKER:
The Lone Star Special provides one OPTIONAL / 35 WATTS (8 ohm) and two MAIN /30-15-5 (4 ohm) speaker
outputs and this enables you to use many different combinations of speaker setups. The MAIN jack is preferred for most vintage
inspired sounds where a smoother, warmer character will be noted in all three power selections and an impedance correct match
will be achieved for the 15 and 5 watt selections and a slight mismatch will occur in the 30 watt
setting where maximum power will be about 30 watts. Using the OPTIONAL jack will produce a
correct match for the 30 watt selection boosting overall power to about 35 watts and producing
a slight mismatch in the 15 and 5 watt settings (which is fi ne and may be preferable) giving all
three selections a little more punch in the midrange frequencies.
The 1x12 combo uses an 8 ohm speaker while the 2 x 12 combo uses two 16 ohm speakers
wired in parallel and this harness connects to the OPTIONAL (8 ohm) speaker output. You should
experiment with different loading conditions as there may be a certain impedance mismatch that
produces a sound you may prefer to the correct load condition. This will not hurt the amplifi er,
however mismatching a lower impedance speaker in a higher jack will wear the power tubes faster. There are sample speaker wiring
diagrams later in this manual. You may fi nd it benefi cial to browse this section to understand more about different ways you can use
your
Lone Star Special with alternate speaker combinations. We build many different types of Extension Speaker Cabinets, all with
unique characteristics, as well as a line of matching Classic cabinets to enhance both the sound and the appearance of your new Classic Classic
Lone Star Special.
SLAVE:
The SLAVE Output and its accompanying Level control provide an output for capturing the sound of both preamp and
power section. This feature may be used to drive additional slave power amplifi ers for big venue applications or to drive a string of
outboard processors when using the EFFECTS LOOP is not desirable. It is not a direct recording output as it derives its signal from
the speaker jacks and is much too strong a signal to connect to the input of a console. Also there
is no roll off of high frequencies or shaping, as the speaker does this, so the sound would be less
than desirable for recording applications. Should you need a direct recording sound, check out
one of our Rectifi er Recording Preamp’s which are designed specifi cally for this application and
has the necessary circuitry to achieve this diffi cult task with stunning results.
NOTE: The signal from the SLAVE Output is powerful. Always start with the LEVEL control set
to its lowest position (7:00) when connecting to anything and bring the level up slowly to avoid
damaging gear (and ears) downstream of the
Lone Star Special.
NOTE: Once a signal has been taken from the SLAVE Output, it can not be routed back into the amplifi er (INPUT or EFFECTS
LOOP RETURN). Doing so will produce a feedback loop resulting in a high pitched squeal much like holding a microphone up to a
monitor.
REVERB REMOTE JACK:
The Reverb feature contains a REMOTE SWITCH JACK that allows you to control the Reverb
effect from a separate footswitch. The 1/4” jack is located on the underside of the chassis just below where the SLAVE jack is located
on the extreme right side of the Back Panel. Connecting any tip-to-ground, latching-type footswitch will allow
you to toggle on and off the Reverb effect. Use a shielded cable for this application. You should be able to
fi nd this type of footswitch at most music stores or, you can call our Customer Service department and order
one for a nominal charge.
If you have any questions or concerns unanswered in this guide, please feel free to call our Customer Service
department and ask for a Product Specialist who will be glad to help you get the answers you need.
Cheers and Enjoy!
