When it comes to fast picking on any acoustic if I don't have my Dunlop 1mm I feel at a disadvantage. I went out back to play some guitar and could not find this pick. Instead of playing I spent 20 minutes looking for one pick (even though I probably have 50 others). I have picks that cost $5 each but when it comes to playing my mando, acoustic or 12 string this is the only pick for me. That is why I ordered a bunch. I should wear a Dunlop shirt!
