Real And Innovative Design. These guts are the mesh between our hunting guts and stage guts. They have the versatility to produce your typical hollow goosey tones and that sharp crack that contest callers look for. The Raid gut set would be great for the live stage and the field. With the more traditional goose call sound and the ability to get loud or gravely. These guts are sure to produce every sound you look for in a goose call. If you want a gut that can be tuned light or stiff these are the ticket.
