the first pocket operator, so number   
     twelve of course. aka po twelve.     
                                          
                                   
                                          
    naked circuit board in a silicone     
   shell. if you purchase the silicone    
  shell for an additional hundred percent 
    of the original price. it's a drum    
                  machine                 
                                          
    it's very small but has very decent   
    sounds. you can use it. control is    
   limited. it's rigid. it's crisp. it's  
            hard to deal with.            
                                          
                                   
                                          
  see po sixteen, other pocket operators, 
         or just some other gear.
