CLEAN PREAMP SECTION
The Clean Preamp is designed to imitate (and surpass) all of the “classic” guitar amp preamps. The CDS3 Mode
control gives the player the ability to shift the midrange center point frequency.
Bright Switch
– Center = OFF, Down = sound of new strings, Up = normal Bright response.
Volume
–
Typical setting is between 3 and 5 but experimentation is encouraged.
Treble Control
-
Adjusts highs (also upper midrange when the Boost footswitch is engaged, see
the
Other Features
section of this manual for details
).
Middle Control
–
Controls the amount of Midrange frequencies, somewhat interactive with the Bass Control.
Bass Control
– Sets the amount of low end. Can be rotated to zero where it clicks off for a full tone stack lift.
Mode Selector
– A six position rotary switch, it steps through 5 progressively fatter positions of the midrange
center frequency and achieves maximum fat midrange by lifting the Middle control in position 6.
DRIVE SECTION
The Drive section controls the amount of character to add to the
Blackface channel’s tone. The section’s range
of effect can be just a hint of early break up or a full on aggressive heavy metal distortion.
Gain Control
–This control sets the amount of signal for the first gain stage of the section. Low settings are
smoother and higher settings are more aggressive. When you rotate this control to zero it bypasses the
overdrive section. Overdrive will
not
engage when the Tweed channel is manually enabled on the front panel.
Drive Control
– Sets the amount of distortion by controlling the level between the 2 gain stages of the section.
The interaction of the Gain and Drive controls affects the tone of the overdrive.
Level Control
– Sets the output volume of the section. This control is shared with the Tweed Preamp.
Pull this control to engage a high frequency roll off that only affects the overdrive tone.
