A Diamond pick but in Large size. Clean, clear, and FAST. Lots of mid-range. Singing quality. Huge, giant, strong tone! Incredible speed, rolls off the strings like butter. Sounds like you're really attacking your guitar, even though you're playing with a very light touch. Lots of gripping action, so you won't be adjusting or thinking about this pick during a show. This is an amazing pick indeed! Remember, once you've been bitten by the SNAKE, you will never be the same! 4.10mm thick.
