A stringed instrument bridge comprising: a bridge body; a receiving surface located on the bridge body; a first angled member abutting a first side of the receiving surface, the first angled member having a first angled surface with a first threaded hole; a second angled member abutting a second side of the receiving surface, the second side on an opposite side from the first side, the second angled member having a second angled surface with a second threaded hole; a plurality of saddles, each saddle configured to sit the receiving surface; a first wedge lock, the first wedge lock having a first slotted screw hole, the first wedge lock configured to attach to the bridge body at the first angled member via a first screw configured to engage the first slotted screw hole and the first threaded hole; a second wedge lock, the second wedge lock having a second slotted screw hole, the second wedge lock configured to attach to the bridge body at the second angled member via a second screw configured to engage the second slotted screw hole and the second threaded hole; where when the first and second wedge locks are loosely attached to the first and second angle members, the saddles may be adjusted into an adjusted position with respect to the receiving surface; and where when first screw is tightened and the second screw is tightened, the first and second wedge locks fixedly hold the saddles in the adjusted position. The invention also relates to a saddle for a stringed instrument bridge, the saddle comprising: a first threaded hole extending from the bottom side to the top curved surface on the first side of the peak; a second threaded hole extending from the bottom side to the top curved surface on the second side of the peak; the first threaded hole and the second threaded hole are both offset from the longitudinal centerplane and configured to allow tool clearance from and instrument string; and an unthreaded through hole from the first vertical planar surface to the second vertical planar surface, the unthreaded through hole having a domed shape; a retention wire threaded hole extending from the bottom side up into the bottom surface of the unthreaded through hole; a retention wire set screw configured to screw into the retention wire threaded hole and further configured to impinge a retention wire against the top surface of the unthreaded through hole; and the domed shape configured to center a retention wire over a retention wire set screw.
