SPEED HOLE                
                                
                                          
 TURN  YOUR  WALKMAN LIKE A TURTLE. THERE 
 MIGHT  BE  SOMETHING  THERE  THAT  LOOKS 
 LIKE A SCREW HOLE  BUT  IT  COULD  BE  A 
               SPEED HOLE.                
 THE   RULE   IS  IF  YOU   CAN'T  GET  A 
  REASONABLY SMALL SCREWDRIVER IN THERE,  
          IT'S NOT A SCREW HOLE.          
                                          
                 USAGE                  
                                          
 USE  THE  SPEED HOLE  LIKE A  SCREW HOLE 
      BUT WITH A TINIER SCREWDRIVER       
                                          
                  THIS                  
                ADJUSTS                 
                   THE                  
                PITCH                 
                                          
 SOME  CASSETTE PLAYERS HAVE SPEED SCREWS 
 BUT NO HOLES  FOR  THEM. TO GET TO THOSE 
 SCREWS  YOU   NEED  TO  DISSASEMBLE  THE 
 WHOLE   THING.   COULD   BE   WORTH   IT
