Hi. Even though there are plenty of guitarists that think otherwise, I currently believe there's an audible difference between maple and rosewood necks and here's why. My JTV-69 (with a rosewood fingerboard) was overdue for either a fret job or neck replacement and I found a JTV-69 neck for sale, so went with that. This new neck happens to be maple and I didn't think it would effect my sound much at all, but it clearly has in some respects. On the plus side, my clean sounds have more note definition playing chords and I have more natural sustain, mostly from the new frets, I assume. But if I strum or pick agressively, the sound can get more harsher on the high end. Also, distorted presets are now pretty muddy in the low end. With my Helix, the global eq would be the way to go, I think, with some high and low cuts, which I've just started experimenting with. But, I'm curious if there's anyone here, like a luthier, who believes this difference still couldn't be related to the different necks. The neck fit perfectly. The bolt holes lined up. After attaching the new neck, I changed the tuners (to Gotoh) and tweaked in the action and intonation. But this is my first time changing a neck on a guitar, so maybe I missed something that could have caused this problem. Any non-snarky experts out there willing to chime in on this?
