1-2 months is a LONG time compared to my strings which rust in 3-4 days. until i bought fast fret
it lasts much longer now before rusting. amazing how much RM20 can save you in the long run

its a bit oily, but you'll get used to it too. plus, it makes sliding a lot easier
what i do is apply some on my strings and wipe it away thoroughly before i play. not all the oil will be removed though. you can still feel it. after i play, i wipe my strings and apply a whole lot of fast fret and leave it that way

double the price but triple-quadruple the lifespan
i used to use elixir strings. lasted for 3 months + before i snapped one due to over-tuning some people use elixirs for like 6 months and its still bright sounding add that with fast fret....
now i've switched to d addario cuz i cant find 10-52's in any other brand besides d addario near my place

yeah, my strings rust THAT fast. on d addario anyway, havent tried ernie balls

but now with fast fret, it makes a whole world of difference

i don't put my guitar in the bag, i leave it on my stand
that might be a factor... condensation ?
