The PQ-9125-00 is 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. TUSQ delivers a rich tone, crystal clear bell like high end with big open lows and a significant increase in harmonic content and harmonic sustain. Increase harmonics equals more richness and character in your tone. Its the difference between a four piece choir and a twelve piece choir singing every time your play a note. Dimensions: 101,83 x 3,27 x 12,85 mm.
