Input 
Plug your guitar in here!  

 

Volume 
This adjusts the input sensitivity. Use low settings for maximum clean headroom and higher settings 
when you want to introduce more natural valve overdrive to your tone. 
Balancing your input Volume level with your master volume level is crucial in delivering the tone and 
feel that works best for you. 
 
Voice I/II switch 
Switched the Voice I, the V40 has a relatively flat response for an American Style sound. Switching to 
Voice II adds more upper mid-range frequencies into the mix for a more traditional British Style sound. 
 
Treble 
Controls the high frequency content of your sound and is also a powerful tone shaper when it comes to 
overdrive character.  
 
Middle 
Controls the midrange frequencies in your sound. Run the middle control higher to help cut through a 
band mix, or generally fatten and ‘widen’ your sound. Run it lower for a lighter, less ‘in-your-face’ kind 
of sound.  
 
Mid Kick switch 
When switched ON, (downwards), this will add more mid-range frequencies while boosting them at the 
same time, allowing the Middle Knob to have a wider sweep and range of frequencies to control.  
 
Bass 
The Bass controls the low frequency content of your sound. Higher levels of bass can be good at low 
volumes, but take care when running the amp louder – you may find you need to reduce the bass 
control. As with all the EQ pots, adjust to taste! 
 
Reverb  
The V40 has a built-in Digital Reverb and this control varies the amount of Reverb added to the guitar 
signal.  
 
Reverb ON/OFF switch 
The Digital Reverb can be switched ON/OFF using this toggle.
