Fred Kelly picks are top class, but if I Had to choose just one of their range it would be these. For me the speed pick promotes the best touch sensitivity and accuracy of all thumbpicks I’ve used. The delrin offers a warm tone and the speed pick shape seems to provide a stronger bass response than the regular shaped thumbpicks. Comfortable, durable and easy to customize the blade length if required. The medium thickness picks seem well suited for guitars that prefer to be driven a little softer, such as cedar top instruments.
