At Pickboy that's been our motto since 1967 and we've been on a quest since then to bring guitarists the best sounding and playing guitar picks.
Felt is a traditional material for picks. It's used on many classical instruments to give a finger or deader tone. Pickboy felt picks are like an ice cream sandwich; our standard celltex pick sandwiched between 2 layers of felt. This helps produce a nice warm tone and a nice bit of thump at the start of note.
Pickboy triangle felt picks are great for the dialing in the "classic" early rock and R&B bass tone from round wound strings. The 11PH has a medium feel and produces a nice round and warm tone.
Felt picks sound great on electric, acoustic guitar, mandolin, ukulele and also bass.
