I'm trying to figure out what gauge of an E string I should use with Circle K, with standard tuning, on a pbass. You know that set that Fender ships their basses with? The 100-to-45 one? I really like the feel of that 100. The 105 E in a DR Sunbeam set is too floppy for me, but I love the feel of a TI Jazzflat E. The Fender 100 E feels slightly tighter & stiffer than the TI Jazzflat. [edit: Oops, I meant jazzflat, not jazzround! The jazzround, from what I've read, is definitely too "noodly" for me) It's been so long since I've played anything else that I don't remember what a D'Addario or Ernie Ball feels like, but I seem to remember that a DR Black Beauties 105 felt good. The nut of the bass I'm throwing the Circle Ks on looks like it's perfectly cut for a 100 E.
