I put a new set of D'Addario EXL170-6 on my bass last week and WOW. I play an Ibanez SR506, gospel music and it sounds amazing, tone for days. I replaced the DR Fat Beams with the new D'Addario's and I love the feel and sound of the nickel. These are definitely bright strings, just right. I liked the Fat beams but I think I am in for D'Addario from this point on. I have found my sound.
