Ever since I got my new Spector NS-2-JA-R last November it hasn't kept tune very well. Every new day I found it slightly off, usually sharp but fairly evenly across EADG. Where I first thought the tuning keys were responsible I eventually chalked it up to temperature changes in my apartment causing the neck to move. But no buzzing has occurred. I do my own setups. Since the weather warmed up here it stabilized. I am now thinking the culprit may be the DR High Beams. I have Roto 66s on my Tele. I tend to pluck hard but I have never had a tuning issue with that guitar. Thoughts, ladies and gentlemen?
