 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.
