Sometimes people get confused on the gauge size of metal finger picks and I'm here to clear the confusion! The gauge size determines how thick the metal of the actual pick is. So a metal finger pick that has a .025 gauge thickness will be a thicker, more stiff finger pick, whereas one with .020 will have more give and be thiner. Hope this helps you when purchasing your next finger picks! Shop finger picks at the Banjo Ben General Store! #bluegrass #bluegrassmusic #fingerpicks #banjoplayer #guita
