DIRECTIONS
8
A) Run a cable from your guitar to the Fullbore Metal’s Input jack and  
 run another cable from the Fullbore’s Output jack to your amplifier. 
7
B) IMPORTANT! Please note, that this pedal is extremely dynamic,  
 therefore care should be taken during the initial setup by starting  
 with the VOLUME, GAIN, and BASS controls at fully counter-clockwise  
 (minimum). 
C) Turn the effect on by depressing the footswitch. The illuminated  
 Blue LED indicates that the unit is on. 
9
D) Adjust the GAIN, VOLUME, LOW, MID, FREQ and HIGH controls until  
 the desired output and tone is acquired. 
E) Depress the SCOOP switch for an instant nu-metal scooped sound  
 that accentuates the low and high frequencies. The illuminated Red  
 LED indicates you are in Scoop mode. 
F) To sharpen the attack of syncopated rhythms or to cut down on excess  
 noise, depress the GATE button. The Green LED will illuminate when  
 the Gate function is active. To adjust the GATE control's sensitivity,  
 please refer to diagram A.
