Hey guys. I'm having a bass built and was wondering: -A search revealed one saying that a zero fret virtually accomplished what BFTS was designed for.Does it? -My neck will be built by USA Custom with zero fret,but the BFTS would be installed later.I'm imagining this to be a technical nightmare.Would it be in your experience? Would it be unnecessary redundance? *Of inccidental reference I notice McCartney often played higher on the neck and claimed it was because the Hofner was light and lended itself.He had a zero fret added to his Ric 4001.McCartney claims himself technically inept in my Beatles Gear book,but he must have heard something that compelled him to carry this feature over.Any comments? Thank you for your time.
