The PQ-9400-00 is a great option to replace or upgrade the saddle on your Gibson acoustic as well as many other popular guitars. It is 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.
