A conventional guitar pick is retrofitted with a special adhesion material covering a selected surface region of the pick so as to enhance gripping between thumb and finger for playing and to provide convenient temporary storage, when not in use for playing, by temporary attachment onto a nearby object such as the body of the guitar. The adhesion material, specially structured to utilize suction to grip onto any smooth surface without leaving marks or residue when removed, is adhesively attached to the pick in the form of a tape or film to provide a suction gripping surface formed by special structure ranging, from multiple articulated suction cups integrally molded from rubber-like material in a uniform grid pattern, to foam-like material with a random pattern of suction pores of size ranging down to microscopic.
