Picked up my US deluxe Fender strat (1998 model) a couple of months ago, and was getting a weird resonant sound. Took off the scratchplate and backplate to make sure nothing there was resonating. We seemed to have tracked it down to the neck, but as it didn't sound anything like fret buzz, we assumed it was the rod. The rod was already tight, but a small tweak seemed to cure it. However, a month on and I've been playing it again, and it seems the noise has come back, except at low Db (strings 5 & 6) instead of Bb at 11th fret, 2nd string and 3rd fret, 3rd string. So: anyone had something similar? Is it fixable and if not, is it worth going with a Fender replacement neck? I'm not all that worried about staying all-original - it's a guitar for playing, not gazing at. Cheers guys. I await your sagacious responses!
