 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.
