The PQ-9276-C0 is a great option to replace or upgrade the saddle on your acoustic guitar. It is 3" long and compensated to help improve the playability of your guitar. 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.
