The PQL-6060-L0 is the perfect option to replace and upgrade the nut in your left handed Epiphone guitar. It also will work on many other common guitars.
engineered from the same material as TUSQ, THE TUSQXL is impregnated with PTFE - five times more slippery than graphite. It has all the tonal benefits of TUSQ, bringing out the hidden harmonics of your guitar all while drastically improving tuning performance.
TUSQ XL is consistent from piece to piece, and within each piece, to offer you harmonically rich tones without the problems associated with natural materials.
