Knob Functionality 

1.

 

Vol(ume)

 - Adjusts the overall volume of the unit. The fully counterclockwise 

position is zero.

 

2.

 

Gain - 

Adjusts the amount of gain in the unit. For cleaner settings, rotate 

counterclockwise. The maximum gain in the pedal is also limited by the Voice knob 
settings. To set the maximum gain in the pedal, the Voice knob must be rotated fully 
clockwise.

 

3.

 

Voice

 

-

 “Tunes” the pedal to the amplifier and guitar. The Voice knob performs two 

functions:  

a.

 

Limits or increases the total amount of gain in the pedal. To limit the gain, 
rotate counterclockwise. To increase the gain, rotate clockwise. 

b.

 

Adjusts the bottom-end response of the pedal. To increase the bottom-end 
response, rotate counterclockwise. To reduce the bottom-end, rotate the 
clockwise. Remember to adjust the Gain knob to compensate for changes in 
the overall gain of the pedal which occur during the Voice knob adjustment 
process. 

 

4.

 

Tone

 

-

 Performs a basic “high cut” function. With the Tone knob set fully 

counterclockwise, high frequencies are fully attenuated.   

5.

 

In/ Out Jacks - 

Connect a cable with a 

¼

” plug between the guitar or the output of 

another pedal to the 

In

 jack.  Connect another cable with a 

¼

” plug between the 

Out

 

jack and another pedal, amplifier or recording device. 

6.

 

9V DC Adapter Jack

 

-

 All pedals (except the Zendrive 2 and Nu-Valve) can operate 

with a 9V battery or a 9V DC adapter. Please use a 9V DC adapter 200mA with a 
center negative plug. 

7.

 

Status LED - 

The LED is On when the pedal is active.  The LED is Off when it is being 

bypassed. 

8.

 

Bypass Footswitch - 

Works in conjunction with the LED. Indicates when 

electronics are active. 

9.

 

9V Battery Clip -

 In pedals that operate with a 9V battery, remove the screws on 

back cover and the battery clip will be located close to footswitch. Ensure that the 
clip is connected correctly before closing the back cover.
