Hey I just have recived Schecter Demon 7 CRB few days ago, i have changed after 3 days string to Daddario NYXL 9,5-44+60 . I have set up action at 12 Th fret from lowest 7 string to 3 mm and highest e string to 2 mm. Going lower than 3 mm gives me buzz first three fretes. I guess it is limit or maybe guitar tech could make it lower? I have slight bow with neck like it should be. Its Tune O Matic Bridge. Guitar is tuned half step to Bb Standard Whats your action ?
