Well I have just successfully finished a complete re-stringing of my guitar, its sounding a lot better now! 🙂
Here are some things that I’ve learnt from the experience:
Its very easy to send the pegs pinging off while trying to tighten up the strings.
The thin strings should be tightened with care as they are very easy to break (thats how the whole thing started).
I seems that when re-strung, a lot of tuning should be expected while they settle.

Quite a coincidence that less than a week after my guitar teacher advised me to only bother changing the strings when they break when *SNAP* the E sting goes. Slightly disappointing that while trying to tune the replacement I bought…. *SNAP*… but I’ve learned my lesson and now everything seems to be good. 🙂
