ChickenPicks guitar picks are unique in its design and manufacturing process. Developed by Eppo Franken in 1985. These are some of the best heavy guitar plectrums among many guitar players. The beveled edges allow to glide on and off the strings effortlessly making it easier to play (as compared to a conventional thic k- or heavy plectrum). The thermosetting plastic, the material used, is much harder and denser than all other plastics, avoiding chipped edges. As a result less chirp and other kinds of pick noise. These ensure you years, of uninhibited, uninterrupted playability, whether you play guitar or use them as bass guitar picks.
