The Dual Boost pedal 

(Diagram D)

 offers two distinct clean gain 

levels selectable by a footswitch.  

The Dual Boost has the following configuration: 

1.

 

Gain A, Gain B, Tone and Voice knobs 

2.

 

In/ Out jacks 

3.

 

9V DC adapter jack 

4.

 

Status On/ Off LED and Gain A and Gain B LED indicators 

5.

 

Bypass footswitch (true bypass) and A/ B toggle footswitch 

6.

 

9V battery clip (located inside the unit) 

Dual Boost Pedal Operation

 

1.

 

Install a battery or DC adapter plug into the unit and connect the audio signal from a 
guitar or another pedal to the 

In

 jack. Connect the 

Out

 jack to another pedal or 

amplifier. 
 

2.

 

The Status LED (lower middle) indicates if the unit is active (LED is On) or  in bypass 
mode (LED is Off).   
 

3.

 

The Gain A and Gain B LED indicators are located under the corresponding Gain 
knob. One of the two LEDs should always be On when there’s power supplied to the 
unit. The LEDs indicate which Gain channel will be active when the Status LED is On. 
 

4.

 

The Gain A and Gain B knobs are independent of each other and the A/ B footswitch 
can only select A or B. 
 

5.

 

To fully bypass the unit, press the On/ Off footswitch. The Status LED should turn 
Off.
