I bought this pick for an electric guitar. I really like thicker picks, because the thin ones are so uncomfortable for me, but it fits perfectly to my playing style. The durability is quite brutal. This stuff is almost indesturctible, even though I use quite thick strings, 12-68 for Drop Bb tuning. Plus I play guitar everyday two or three hours.
The feel of this pick is awsome. It doesn't slide out of my hand.
The rhythm parts are heavy and clear and if you want to play solo or lead stuff, this thing does its job well. The movements are so fluent with this.
Of course the price is higher than a "regular" pick, but the durability compensates this fact.
If I want to summarize, I could say that, this is an awsome pick, which will be perfect for rhythm and lead parts as well. Keep in mind that the higher price comes with a better durability and quality. This is not Dunlop Tortex or Gator, which are good picks, but this is so different. One cons about this and it is about more personal preference. If you do not like thick picks, you will hate it, and I do not recommend to buy the Dunlop Primetone 3mm XL pick. Otherwise you can not make a mistake with this stuff in my opinion.
