Yeah - they're on my bass right now.

RE: Clank
I guess it comes to getting the right tension - I've found the rounds that work for me, but not the flats just yet.
I used them in the studio bout 2 weeks ago, with a bit of success, but just wanted a bit more tension down in C tuning.
I only tune down in C - so my bottom is important to me.

I *think* they're chromes, but I can't quite remember.....
So the Jamerson's are pretty tight?
How do they feel to the
sliding fret fingers?
I like to do a lot of slides and bends. They good for this too?
