When you need a thumb pick for your guitar, the Jim Dunlop Zookies sold at Strings and Beyond are a popular choice at an affordable price.
Zookies thumb picks from Strings and Beyond feature a 3-angle tip with options of 10 degrees, 20 degrees or 30 degrees so you can choose based on your personal preference. The angle options allow the player to have a more natural hand position as well as better string contact. This is achieved by the pick's construction. When you play the guitar with this pick, the tip will be parallel to the string so that you don't need to fight to have good technique. Use your Zookie or Dunlop thumb picks immediately because there is no "wear-in time" required, and the secure fit will be comfortable and easy to use.
