Current GRETSCH SynchroSonic Bridge - Chrome This is a new item for sale. There's a reason for this. The SynchroSonic bridge comes with flat-head screws to secure the saddles, but these are missing, so I've attached different screws and washers. The screws for the SynchroSonic bridge are in inches, so it's difficult to substitute with other screws. Of course, the original height-adjustable thumb screws are included. - Model: Guitar Bridge - Material: Metal - Color: Silver - Included: Adjustment screws Thank you for looking.
