i find that i’m changing my strings around every 3 weeks and currently using GHS 135 and have a good few sets of GHS 155 also… i wouldn’t say i’m changing every 3 weeks because the strings are totally gone but i find that they start to loose a bit of tonal edge and defo loose their ability to hold the note
changing to a new set gives me momentum and renewed playability/enjoyment, which has to be worth the £6 every 3 weeks
Keep Picking Y’All
