HI/LO POWER Switch
– (If Present - Domestic Version only) Changes the voltage on the
power amp input stage (Phase Inverter tube) so the amplifier breaks up sooner.
Pentode/Triode Switch
– (If Present - Domestic Version only) Changes the output tube from
pentode to triode mode resulting in a drastic power reduction and change in feel, great for small
venues.
Impedance Selector Ω
- Set this to the total impedance of all attached speakers. When 6V6
tubes are used, set to the next lower number.
Speaker Jacks
– The MAIN and EXT jacks are wired in parallel. The MAIN jack must be used
first because it has a protection device. ALWAYS HAVE A SPEAKER CONNECTED TO AVOID
PERMANENT AMPLIFIER AND OUTPUT TUBE DAMAGE.
LINE OUT
– A line level signal jack derived from the speaker output which contains the whole
tone of the amplifier.
SEND and RETURN Jacks
– The send jack connects to the input of an external effects device
and the return jack connects to the output of an external effects device. The return jack interrupts
the signal path so the external effects unit must mix the wet and dry signals.
Footswitch Jack
- This is a standard 180 degree 5 pin DIN jack for footswitch connection. If a
replacement cable is needed, make sure all 5 wires are supported. The pinout is conveniently
located on the rear panel for use with automated switcher conversion boxes.
OTHER FEATURES
The TweedyDrive comes complete with a 3 button footswitch and a footswitch cable. The cable
used is a regular MIDI cable and is readily available in any length at most music stores.
FOOTSWITCH
TWEED
– Mode Change feature. When engaged, the preamp goes into one of the Tweed
positions of the Mode Switch. If the panel Mode switch is set to 1 or 3 it jumps to 5, panel set to 2
or 4 jumps to 6. The footswitch button has no effect when position 5 or 6 of the rotary MODE switch
on the front panel is selected because it is a duplicate function.
DRIVE
– Character Boost feature. When lit, the Drive section of the amplifier is active, not lit,
means the section is bypassed. The footswitch button does not work when the front panel Gain
control is rotated to zero because it is a duplicate function.
