MAD PROFESSOR - SKY BLUE OVERDRIVE - OWNER’S MANUAL
Thank you for buying the
SKY BLUE OVERDRIVE!
SKY BLUE OVERDIVE (SBOD) is a high
quality overdrive designed by Björn Juhl.
SBOD is great for overdriving already
distorted amplifiers as well as providing light
overdrive or soft distortion to clean sound.
Special feature on this pedal is that you can
adjust the feel and dynamics with Texture
and Z knobs.
You get the most out of this pedal with pas-
sive pickups and with no buffered pedals
placed before the Sky Blue Overdrive.
The controls are:
• DRIVE controls the distortion or overdrive
effect
• VOLUME sets the output volume of the
effect
• TEXTURE allows changing how and when
the circuit distorts as well as adjusting over-
all EQ. Dialing this control appears to adjust
midrange, while in fact adjusting compres-
sion. Turning CCW gives more saturated
effect that is easily distorted, turning CW
gives a slight treble boost and less com-
pression (compression is used here to
describe density of distortion since overall
sound may be distorted throughout the dial).
• Z is a control that creates an adjustable
load to the instrument connected to the
SBOD input. With standard guitars it
adjusts the upper resonant peak of the
pickups and also affects the taper of the
volume control for easy setting from clean
to distorted just with the volume control of
guitar. This effect is masked if SBOD is
driven by a buffered output source such as
another guitar pedal or active pickups.
CAUTION!
Never operate the unit with its bottom
removed of damage will most likely occur.
