Thanks. Was just curious. I do the 2.4mm —> 2.0mm range myself, but might start going a touch lower.
Try lower the saddle until dint appear fret buzz with your playing style.
On my setting, only get tiny fret buzz on fret 10th the D string(TiJF344 ) if I deliberate it hard. No problem with others string.
Setup the bass is fun thing and good learning for myself.
