The ABM 3022 PRS Style Wraparound Bridge is milled from a solid block of brass for superior quality and tone with precision cut string slots. In addition to the compensated string slots there are allen/hex screws behind the bridge posts that can be adjusted to move the whole bridge backwards and forwards and also slant it to add more intonation room to heavy bass strings. The bridge is supplied with imperial 5/16-24 threaded (PRS USA spec) bridge posts and body anchors/bushings and fits the PRS 81 mm wraparound post spacing (please note wraparound bridges usually have an 82 mm spacing and so this may not fit non PRS guitars).
