 i   don't   know  much  about  this  one 
 because i  broke it  instantly.  it's  a 
 walkman   anyway,  runs   off   of   the 
     standard two double a batteries.     
                                          
 it has  a  switch for normal tape versus 
 copper oxide  /  metal.  it also  has  a 
 switch for  something called  avls  (can 
 be    set    to    norm    or    limit). 
                                          
 it  has mega bass (on  or off) and dolby 
 nr (on or off) and two band eq  (i think 
         thats the dolby thing).          
                                          
 it  does have  a  speed hole  which  i 
 found  out about by destroying it. like, 
 thats how i found out about speed holes.
