Rich Robinson Brass Slide D'Addario has worked with Rich Robinson of 'The Black Crowes' to create a new and unique brass slide. The Rich Robinson Signature Brass Slide brings you the crisp, bright tone of a brass slide with a unique taper inside, making the slide form comfortably to your finger. This taper helps prevent the slide from moving, giving the player extra control and comfort while performing.
