I have recently purchased the aforementioned guitar and I absolutely love it. I have noticed a few issues with it holding tuning and have decided to replace the nut with a Tusq XL and upgrade the tuners to locking. My tech reached out to me and asked if I was sure about the nut replacement as he suggested the current nut that came with the guitar was a synthetic bone with bronze blend and would be superior for tone. This contrasts all of the research I had previously done on this, which has stated the TUSQ is superior for both tone and tuning stability. Thoughts?
