I just started playing ukulele 3 weeks ago. I started on a little toy uke that was $35. I just upgraded to an Ohana 35G. I got the uke in today and couldn't wait to get home from work to play it! To my surprise, the E and A string make an annoying buzz and vibration noise near the tuners. I cannot play any normal music without that buzz driving me crazy! Does anyone know what to do to get ride of it?! Please, help me!
