So I have an odd predicament here. It is involving my very beloved fender stratocaster. Awhile back, I put a warmoth neck on it. Rosewood fingerboard, 59 roundback profile, 10-16 compound radius, corian nut. It sounds great, and really looks nice on the guitar. There's one little thing that bugs me. For whatever reason, it feels like the top 3 unwound strings aren't ringing out completely. It's like their ability to vibrate are being impeded by something. I can't figure out what though. The action is pretty much right where it needs to be, the relief is just perfect, and I even re-intonated recently to help tuning. It's just from nut to bridge saddle, nothing but pure string, and there is plenty of room for vibration. Can anyone tell what this is or help me analyze it?
