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.
