Artifacts on normal map bake

Hey Polycount,

I'm trying to bake a normal map for this guitar in Substance Painter, but i'm getting these strange artifacts when I test the normal map in Marmoset Toolbag 2.



I don't see these artifacts in Substance Painter



I originally thought it may be the topology on the highpoly model, so I retopologized the highpoly in zbrush but I'm still getting this issue.

These are my bake settings and I've messed with the max frontal and rear distance settings to no avail.



Here is the normal map.  I don't see any artifacts on the normal map, but I put a layer of normal map blue on the affected areas and the issue disappeared, but it would be a pain to paint all this out as it's also showing up on the other parts such as the pickups, whammy bar, bridge, etc. I only showed the body because it's the easiest to see.



Any help would be much appreciated, thanks!
