Something I've been wondering quite long, but never had the time to really try it out myself: Let's say I buy two sets of strings, both with the same gauge, a cheap one and an expensive one. What are the differences I can expect looking at following:
- Staying in tune
- Anything else?
And, as a more general question: How and why (for example because they produce different overtones or whatever) can another type of string affect the sound, if they have the same gauge?
