Perfect drop-in replacement for the Enya Nova Go Sonic Guitar. You can even use the original posts but the new ones have the same thread pitch so you can swap them if you want.I was having issues with the stock OEM saddles. The E & B strings were cutting into the soft metal, widening the slots and causing those two strings to sound like a sitar. The Musiclily Roller Saddle Bridge fixed this issue, not only that but it improved the intonation and tuning stability. Super happy with this upgrade, overall it��s a 100% improvement.
