First Uke (Pono), first post, big buzz

Greetings from Canada folks! Got my first uke last week, a Pono PTE all mahogany tenor. It's very nice. After a couple days playing it started developing a buzz on all notes and got worse the more I played. I figured something came loose inside so I managed to squeeze my hand through the sound hole and sure enough it was the pickup jack nut. I could get one finger on it and tightened it a little - no buzz. It'll come loose again so I'm going to have to get in there somehow with a wrench. Something to watch for if yours develops a buzz.

Cheers, and now back to 'Between the Devil and Deep Blue Sea'.
