Wow, I wouldn’t wish that on my worst enemy! Unless they were an acoustic player.
Ok Seriously, I can’t imagine being stuck with only those to play guitar. I have some, but never play them. FOR ME, they aren’t the best, or even one of the best, at anything. But, years ago, medium plastic picks were all I ever saw my dad or the couple other guitar players I knew use. As soon as I started playing, I quickly started shopping for other pick styles.
