The PQ-6060-00 is the perfect option to replace and upgrade the nut on your Epiphone guitar. It is also a great option for many other common acoustic and electric guitars. It comes pre-slotted to make for a quick and easy install. 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.Warning: This product is not a proper fit for Epiphone guitars manufactured after 2014, as there has been a slight change in their their string slot specs. We have a blank version of this nut (PQ-4025-00) as an available substitute while we work on a slotted solution.
