Classic Overdrive

The Classic Overdrive Plus comes with your
choice of the Ibanez Tubescreamer TS-808
circuit or the DOD 250.  The 3 toggle
switches located on the side combine to give
you a total of 8 different styles of overdrive.  
The "gain" switch changes the gain limiting
resistor to give you either stock saturation or
maximum saturation.  The "bass" switch
changes the tone of the overdrive from the
bright, mid humpy sound of the stock designs
to a darker sounding overdrive with better
bass response and more gain so it doesn't
sound so much like someone stuck a pillow in
front of your speaker when you turn down the
tone knob.  The "Clipping" switch goes from
stock symmetrical clipping to asymmetrical
clipping for more headroom and a more
tubelike sound.  The clipping switch comes
with your choice of germanium or silicon
diodes.  The silicon diodes have the most
headroom and have a more "big amp" tone.  
They also add a volume boost.  The
germanium diodes make the overdrive have a
little more of a fuzzy quality.
