This pick was designed by JD Crowe and constructed to his very exacting specifications. The BCT-JDL is the exact pick that JD uses. The pick bears JD’s initials on the inside between the rivets. It is constructed using a custom designed stainless steel band and a 50/1000 of an inch(1.25mm) thick BlueChip pick. These picks are laser etched, professionally machined, and hand beveled to create the best thumb pick available. Available in small, medium, and large. Right-handed and left-handed orientation.
