Here's what I experienced recently,
I installed a new set last 2 weeks if im not mistaken, then after practicing for 2-3 hours a day for 3 not consecutive days, My D string's coating wear off in the picking area. I don't believe that this is just because of my picking or pick because this is the first time I encounter this kind of problem.
Actually hindi naman issue for me yung pag wear agad ng coating on my D string, my complaint is on my treble strings. Ang issue is, after a week of practice (on and off) yung bottom part ng treble strings ko ay tanggal na yung coating and has corrosion na din. Yung mga tear ng string are aligned sa fret wires from 2nd fret up to 24th fret.
Sa B string ang worst na wear and tear while minor lang naman G and E string
I don't know what happened, kasi ngayun lang naman to. and my fret wires starting to wear na din. ouch.
