Slotted/unslotted, When you want the best! These are made from the tusk of the fossilized Walrus tusks discovered by native Alaskans. These extinct creatures roamed the earth some 10,000 years ago. The native Alaskans sometimes find these tusks washed up on the shore etc. These tusks are processed into nut and saddle blanks; bridge pins and end pins. Some are plain, while others are very marbled or otherwise colorful. Some have decorative dots added (all natural, no plastic!). These are a great addition to your favorite guitar and will increase sustain due to their density. You can also expect more volume, clarity and tonal beauty! Prices range from $120 - $200. visit www.guitargal.com/acc.html for pics and selection. Also Mammoth ivory pins, nut & saddle blanks.
