I was using Dunlop Tortex 1mm for years, and found that they are really good picks but dont last that long unfortunately.
Recently I started using Graph tech TUSQ 1mm picks and was truly blown away by them. They make a huge difference.
As the adverts say they create that ultra harmonically rich sound due to using the same material as Graphtech nuts.
Well, they sound slightly different, yes better, but no as much as they promise. But still there`s an improvement to your sound
The best thing about TUSQ picks is that they are much accurate and much faster.
After couple of months using them, coming back to Dunlop Tortex 1mm might be hard.
Hetfield Black Fang .94. Friend of mine gave me one recently to give it a try. And must say that was a little bit disappointed due to its short life. Those picks last even shorter than Dunlop Tortex 1mm, after few ours they good for nothing. Dont like them at all, even the fact that they have Hetfield signature.
Hopefuly it that essay might help :D
