I bought this bass new in August 2019. Serial number leads me to believe it was made in 2018. Played it very little. Mint condition. I'm not a fan of any bass without fretboard dots, so - this match was doomed from the start. Showing how the low B and E affect the bridge pins as well, that's how it came. I'm assuming that's how they are. Haven't had any issues with slippage.
