Re: squire strat mods
If you have a reliable straight edge, like a steel ruler, you can lay it against the frets and determine if you have a low or high fret. If you can rock the ruler over the 9th fret, it may be because it isn't fully seated and you can push it back into the fretboard to correct the buzz. Check projectguitar.com for instructions on how to do it. If you tap it too hard and set it lower than necessary, you'll just move your buzz to the 10th fret and you'll need to bring it in to a luthier or tech to fix. If the issue isn't the frets but is actually the neck itself, I think you need to decide how much money you want to put into an $80 guitar to make it playable. A decent neck could easily run you more than 80 bucks.
