So the poster about this wanted to spend £50-70 on a set of strings he/she wanted and mentioned nothing about changing them every 6 months. Being flatwounds one would also assume a longer life than 6 months.
I think you have taken the argument somewhere it wasn’t going to justify not going there if that makes sense?! Should we then say no point in Buying an American Fender when having a Mex one will not make a difference in the gigs, gig fees, appreciation etc. Or why are you buying a premium Japanese brand when a cheap Chinese copy will do the same.
Flea changes his strings every gig, James Jameson notoriously didn’t bother, Joe bloggs does it every now and again Mrs Miggins does it a bit more often......., it’s all silly comparisons to say what to do and invent a reason for it.
Get the strings you want at the price point you want to deliver the sound you want, know their lifespan, change them as required by you.
