User’s Operation Guide:
FRONT PANEL CONTROLS:
NORMAL INPUT – input for NORMAL(Fender) preamp.
BRIGHT INPUT – input for BRIGHT(Marshal) preamp.
NORMAL GAIN – sets the volume and the point at which overdrive distortion is produced by the NORMAL
preamp. Set at ¼ for initial setting.
BRIGHT GAIN – sets the volume and the point at which overdrive distortion is produced by the BRIGHT preamp.
Set at ¼ for initial setting.
MASTER – sets the maximum volume of the amp and the point at which the output tubes saturate. The higher the
setting on the MASTER, the sooner the output tubes will saturate rate and produce output tube overdrive
distortion. Set at ½ for initial setting. Use the GAIN to adjust the volume level and preamp overdrive. As the GAIN
is increased the preamp will begin to produce preamp overdrive distortion. Turn the MASTER up for output tube
overdrive distortion. By adjusting the settings on the GAIN and MASTER you can set your desired amount
CLEAN and OVERDRIVE tones.
TONE STACK – is a three band Bass, Middle, and Treble tone filter. The controls are interactive in shaping the
tone. You will need to experiment to find the best setting for your playing requirements. Initial settings for all
three controls is the ½ position
BASS – attenuates the Bass frequencies from 10hz – 100hz as it is turned down.
MIDDLE – is a 500 hz notch filter that dampens the middle frequencies. As you turn the control down it deepens
the notch.
TREBLE – attenuates the high frequency tones from 1000hz - 15000hz. As it is turned down, the MIDDLE control
will have less effect.
PRESENCE – boosts the high frequency range and gives the amp more bright punch. Set at ½ for initial setting.
(Please note that a scratchy noise is normal as the Presence control is adjusted. This is caused by the DC
cathode current running through the contacts. It only occurs when the control is adjusted and does not affect the
operation of the amp.)
EDGE PULL SWITCH – when pulled out will turn off the negative feedback in the amp which produces a boost in
the volume and a more dynamic less compressed tone.
REVERB – adjusts the Reverb level. (Only on amps with the reverb option.)
