D'Addario Casein Mandolin Pick

This D'Addario pick, designed for mandolin virtuoso Chris Thile, is made of Casein to capture the unique feel and tone of genuine tortoiseshell.

The Chris Thile Signature Casein Pick was developed to meet Chris's own specifications for maximum comfort, tone and playability. Casein gives players access to the texture and warm, balanced tone previously found only in natural tortoiseshell picks. The Chris Thile Signature Pick's wide, triangular shape offers added control, and each corner's beveled, pointed tip offers supreme glide and articulation.

D'Addario features one of the widest range of guitar picks in the industry. With various material choices to find the tone you are looking for, to the various shapes to fit your comfort needs, D'Addario has the pick for you. Look no further.

"Too curved to be usable"
Overall: 0.5 out of 5 stars
Verified Customer zZounds has verified that this reviewer made a purchase from us.
Out of the package, this pick is curved quite a bit, about 1/2 the pick thickness, and so far from being flat I found it unusable. I emailed D'Addario about this and they said since it is based on natural protein (but let's be honest, still a manufactured material), a "slight bend ... can happen naturally" and suggested I hold the pick while using it to try and reverse the bend. Seriously. I can't play with a bent pick, and while I do understand that casein *can* bend, I should not have to start with a bent pick. Ridiculous. (And, since I took it out of the package, there's no returning it here.) FWIW, the sound of this pick is rather bright compared to denser high-end "plastics" I've used, more like a Primetone of similar gauge. It feels smooth across the strings, but, of course, it feels very different on up and down strokes because of the curvature.
