If you are into tweed and worn out looking gear these are for you. Tonally they sound like a standard brass Rock Slide®, but they resemble something from the bottom of the Bayou. We individually hand age these using a multi-step recipe of destruction. They have a perfectly smooth finish for playability. DISCLAIMER: Every single slide is aged by hand. Appearance WILL vary drastically from slide to slide. Some look like the picture, some come out with more black, some come out with more golds or rust colors. Inside Diameter: 17.5mm Total Length: 47.5mm Weight: 40g
