What Does This Do?

1.Level Knob - Controls the overdrive output level. Turn the knob clockwise to increase andcounter-clockwiseto decrease the output level.

2.DC Adapter Jack - Connect (an optional) Harman PS200R power supply to this jack. Use the proper supply for your area’s mains line voltage.

3.Low Knob - Controls the level of low frequency (bass) boost/cut. Turn the knob clockwise to increase andcounter-clockwiseto decrease bass level.

4.High Knob - Controls the level of high frequency (treble) boost/ cut.Turn this knob clockwise to increase andcounter-clockwiseto decrease treble level.

5.Gain Knob - Controls the overall overdrive gain. Turn the knob clockwise to increase andcounter-clockwiseto decrease the

amount of overdrive gain.


6.Voicing Switch - This switches between the Overdrive’s two voicings. Classic voicing provides the kind of gain you need for amazingly crunchy rhythms. Modified voicing pushes your amp to the limits with just the extra gain you need for hot solos.

7.Input - Connect your instrument or the output of another pedal to this jack.This jack enables battery power to the pedal when connected.To prolong battery life, disconnect the cable from the Input jack when not in use. If the optional Harman PS200R power supply is used, cables can remain connected.

8.Foot Switch Release Pins - These two pins are spring loaded hinges that hold the Foot Switch in place. See page 7 for information on accessing and changing the battery.

9.Indicator LED - Lights when the effect is turned on. When battery power is low (approximately 15 minutes before it dies), the Indicator LED begins to dim giving you advanced warning that very

shortly you will need to replace the battery.

10.Foot Switch - Turns the effect on and off.

11.Output - Connect this output to the input of your amplifier or the input of another pedal.

Note: Use unbalanced mono instrument cables only.

Amplifier Setup



Battery Operation

In the event that battery power is completely depleted, HardWire pedals automatically switch into bypass.This eliminates the need to remove the pedal from your pedal chain if the battery is dead. To replace the battery, do the following:

. Using the tip of a 1/4” guitar cable, push in one of the Release Pins in on either side of the Foot Switch, and remove it from the pedal chassis.

2.Remove the battery from the battery compartment and disconnect the

battery cable.

. Connect a new battery to the battery cable and put it back in the battery compartment. Make sure the battery cable does not interfere with the spring or pedal switch arm.

. Place one hole of the Foot Switch over its corresponding pin.

5.Push the opposite pin in and lower the other side of the Foot Switch into place over the depressed pin. Release the pin. When the Foot

Switch is properly fastened, both Release Pins are flush with the outer side of the pedal.
