Material: African Ebony, Clear Horn, Black Horn & Buffalo Bone. Instrument: We recommend Groove Tones for Acoustic Guitar, Electric Guitar and Gypsy Jazz Guitar. Tone: Buffalo Bone has very clear clean tones, which can help to add some brightness to the tone of most guitars. Buffalo Horn has very balanced rounded warm tones. Design: Groove Tones are the first choice for anyone who needs a larger, heavy duty Guitar Pick. They have a thick and pointed playing tip ideally suited to any hard use scenario. They also have a large grip area, which has a indent for the thumb and a scoop for the first finger. Contents: This tin contains 1 of each of the Groove Tones Guitar Pick. Notes: Although we have tried to ensure that our photos represent the Guitar Pick that you will receive, there is a high level of variety in our picks due to the nature of many of our natural materials.
