Re: Its amazing what a fresh set of strings and a little set up can do for your guita
I've taught after school guitar lesson at the high school for years. Students bring me dozens of guitars every year that have horrible action setups, rusted strings, ground in dirt etc. There is nothing I enjoy better that handing it back to them the next day with a full setup/intonation, a good cleaning, and a new set of strings and watching the look on their face when they play it. Most of the lower end guitars have REALLY bad setups from the factory, and new players think strings are supposed to last the lifetime of the guitar.
It is also surprising how much a setup can change over time on my own guitars. I spend one evening at least once every 3 months just checking intonation, string height, neck relief, pickup height, String radius, etc and putting new strings on all the guitars I have been playing.
