The Tone knob on the Blue Ranger, is a high cut filter.  

With the knob set at full clockwise, you enjoy the full 

bandwidth of frequencies, so as you turn the knob 

counter clockwise, you start to filter out the high frequen-

cies.  This allows you to fine tune your tone regardless of 

which guitar/pickup you are using.  You might find at high 

gain settings that reducing the highs will tighten up the 

sound, and at lower gain settings, the high frequencies 

will add some bite and crispness to your notes.

Our Bypass button; which switches the Blue Ranger on 

or off,  is True Bypass, which means that you are either 

getting 100% of this great effect, or 100% of your signal 

is going on to the next effect or your amp…no buffering!

The Battery

 is located inside the pedal. To install or replace the 9V battery, loosen the screws on the bottom 

and remove the bottom plate. Be careful not to scratch the unit.

Always remember to unplug your cables from the pedal to conserve battery life. Some battery drain will take 

place when the line cables are connected to the pedal, regardless if the pedal is engaged or not.
