 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.
