The PQ-9125-00is a 1/8" thick blank TUSQ acoustic slab. It is a great option for someone who wants to custom shape a new saddle. A lot of the work is already done for you. The PQ-9125-00 is also available in a convenient luthier 10-pack ( LQ-9125-10) TUSQnuts and saddles have rich tones without the inconsistency found in ivory, bone, and other natural materials. Bone and ivory have hard and soft spots (grain) throughout each piece, hampering the consistent transfer of vibrations to the guitar top. TUSQ nuts, saddles, and bridge pins are designed to transfer the correct frequencies more efficiently from the string to the guitar body. Overview Specs Instructions Overview To be updated.
