Well, the question is how often do you NEED to change them? Are you regularly recording guitars? I never change my strings between projects. After I have recorded all the guitars I let the strings sit on the guitar while I write new songs, then practise them, THEN change and record next project
So I guess I use the same strings for about 6-9 months and then I'm blown away by the difference in sound because I've gotten used to dirty shitty strings.
Oh btw, sweaty hands... let's form a club! I sometimes get very sweaty hands and it just feels as if my hands are a ticking bomb against the guitar. I know the longer it takes me to track something with sweaty hands, the more the strings are degraded. But sometimes I have no hand sweat at all, it's weird. I guess it depends on how stressed you feel while playing. Maybe a glass of wine would help
I tried that once though but I didn't stop at one glass, I downed the whole bottle and ended up listening to Strapping Young Lad and typing here on the forum instead.
Wow, 52 in that low of a tuning, that would never work for me. It would be pure spaghetti!
