Anyone have any info on these? Bartolini doesn't even list them on their site and I really only see them on some of the Ibanez BTB basses (mine is the 675M). Is there a replacement even made? I just replaced the Barts on a Lakland 55-01, which I believe were P2's, with Nordy Fat Stacks and they sound fantastic. Might want to do the same with the Ibanez, I know the 1405 basses already come with Nordy Big Singles. Any help is appreciated, thanks.
