 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.
