just got my 5620T back from the tech. I asked him to address what I believe to be the weak points of the instrument, thanks to everyone here! Let me just say that I am beyond amazed that such a modest investment made a good guitar absolutely incredible. Stays in tune. Capos correctly without a re-tune. And it feels and sounds awesome! Wrench List: Swapped horrid plastic nut for bone nut. Swapped tuners for Grover locking tuners. Swapped stock bridge to a quality roller bridge. Treble bleed installed on volumes. Switchcraft pick up selecter switch and jack. Jack plate added. Fret level and polish. Complete set-up. I am one happy Gretsch owner!
