Hello everyone!

         I just got my first Poly-800 MK1 last Saturday. I'm super stoked cause its my first analog synth! I'm also very grateful for you all in this group. So, I am very interested in the Hawk-800 and atomahawk mods, but I'm a little timid to try the upgrade because I don't have much practice with a soldering iron. I guess when I get tired of the functionality, or lack of, then I'll give it a go. 
      
       Anyway, my volume pot is scratchy. I think I can pull it apart and clean it but what does one use as a cleaner? I've cleaned wha wha pedals pots before and they just get dirty over and over again. 

      Also is it possible to get the Hawk-800 pre-assembled? 

     Has anyone totally destroyed their Poly trying to install the Hawk-800? 

                                Thanks,
                                       J.
