Fingernails for guitarists is all we've been doing for over twenty five years now. I'm not advertising here on this thread, just letting you know that you can have great sounding nails all of the time, and can apply them in less than 5 minutes; If you wish. Some of the best guitarists in the world have been using our nails for many years, including: Eliot Fisk, Grisha Goryachev, William Kanengiser, and many more. And for those of you paying $1.85 each per Rico nail, you can get the same pre-formed nails for less than 20 cents each.You just have to look around.
Anyway, here's a short demo I made of the sound you can get from good artificial nails applied correctly. Recorded directly into an inexpensive video camera.
