High, Mid (channels 2 & 3):
Same basic operation as channel 1 description but exclusively for channels 2 & 3.
Low Control (channels 2 & 3):
Same basic operation as channel 1 description but exclusively for channels 2 & 3. NOTE: This control does
NOT function as channel switching.
Input/Output Overdrive Controls (channels 2 & 3):
The overdrive stage, as mentioned above is fed from the clean preamplifier. Two controls effect
overdrive
:
(see below)
A) Overdrive Input:
(Front panel) sets the amount of distortion content, by adjusting the drive between
the two overdrive stages.
B) Overdrive Output:
acts to balance the volume of the Overdrive channel with the clean channel.
NOTE:
There are no “correct” Overdrive settings, finding the desired tone setting depends on the
guitars/pickups used, as well as your own personal tastes. (Note: An internal trimmer pot, factory set at
approx 1/3 rotation, sets the amount of signal fed from the clean channel into the overdrive stage's first
tube. It also determines the type/quantity of overdrive required, and gain of the preamp tubes. This can
be adjusted- please contact us prior to attempting this)
Master Volume (Channels 2 & 3):
The master volume adjusts the overall volume of the amp for channels 2 & 3 ONLY and works in
conjunction with the Channel 2/3: GAIN, INPUT & OUTPUT controls for overall volume of the amplifier.
NOTE: For TDS 50/100 owners, the MASTER control serves to control the 50 or 100 watt output. IN is
100 watts, OUT is 50 watts.
Accent Control (channels 2 & 3):
The accent control works within the power amp section, reducing negative feedback
at higher frequencies. It adds an edge to the overall amplifier tone. It's excellent for
cutting through in a band or a recording mix. It can also allow greater ability to
selectively make notes feed back and "sing".
Reverb Control (ALL channels):
The reverb control adjusts the level of desired reverb for ALL CHANNELS. This control does not entirely
turn reverb on or off although by reducing this control to its minimum can in effect turn off perceptible
reverb. To completely turn on/off reverb, use the optional “reverb on/off” footswitch available from your
dealer.
LED Power light:
This light indicates if the amplifier is seeing AC power.
