 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.
