1. AC Adaptor Jack: Connect an AC adaptor (100-140V/50-60Hz).
An AC adaptor allows long and secure operation without worrying about
battery life.
Use the proper supply for your area’s Mains line voltage.
2. Indicator LED: This LED indicates when the effect is turned on.
• Operating on battery power only: when the LED becomes dim or does
not light the battery needs to be replaced.
INSTRUCTIONS
Thanks for purchasing our product. In order to make the best use of your
SD-100, please read the following carefully.
FEATURES
The SD-100 is equipped with dual gain circuitry. It offers a warm and soft
distortion sound. Set the SUSTAIN to create long sustain. This SOFT
DISTORTION is a totally new pedal effect for guitarists.
3. Level Knob: Use this control to adjust the level of the effect sound.
4. Low Knob: Use this control to adjust the low frequency of distortion. Turn
this knob clockwise to emphasize low frequencies and create a tight and
thick distortion.
5. High Knob: Use this control to adjust the high frequency of distortion. Turn
this knob clockwise to emphasize high frequencies and create a clear and
sharp distortion.
6. Sustain Knob: Use this control to sustain the distortion. Turn this knob
clockwise to lengthen the distortion sound and counter-clockwise to
shorten it.
7. Dist Knob: Use this control to boost or cut the distortion. Turn this knob
clockwise to increase the distortion sound and counter-clockwise to
decrease the distortion sound.
8. Output Jack: Use this jack to connect an amplifier or other units for mono
output.
9. Pedal: Press the pedal to turn the effect on and off.
10. Thumb Screw: Loosen the screw to open the pedal for battery
replacement. (For details of the battery replacement, see “BATTERY
REPLACEMENT”)
