Great aren’t they, they have been my string choice for the last few years after sampling a set, nice tension and sound, they mellow slightly over time , but not too much, they also sound good on a precision , nice playing cam 👍
Maybe push the pickup in a bit to take the pressure off the screws when you are unscrewing , I’m guessing there’s foam or a spring underneath pushing it up 🙂
The D and G strings do sound a lot quieter with the thumb, so I tend to add a bit more pressure to compensate or turn the volume up a touch, I also find some Basslines sound better, especially some of Flabba holts ones, he plays with the thumb a lot
