Let me start by saying, I LOVE TIJF's. I crave those killer mids that slot you into the mix perfectly. On a P Bass, there is not much better than that. But the problem..... while I love the low tension, my current band is playing in Eb, and the TI's are proving to be just too uncontrollable at Eb. I've been playing D'Addario XL's .... .045 to .105 tuned down, and they rock.... but I really miss the flats. Someone here posted that they would have a tough time hearing the difference between the TI's and the Sadowsky flats. So, I've finally gotten a set of them in, and got them strung up on my '08 Custom Shop '59 P this morning. I'll say this..... I've never played a set of flats that sound this good right out of the pack. They don't sound quite as woody as a broken in set of TI's, but we'll see how the break in (New TIJF's don't sound all that woody either). They don't have the hi mid zing of the Chromes. Definitely don't have the highs of Labellas or the old Fender flats (I have a set of each here that are both well over a decade old and completely broken in...... I've just re-tried both sets over the last few weeks). And definitely not as scooped. I went with the .045 to .105's..... they feel pretty good. Not nearly as stiff as Chromes, but a heck of a lot more controllable than the TI's when at Eb. I probably could have gotten away with the lighter set of Sadowskys.... but we'll see how they feel over the course of the next few weeks. Most flats tend to "loosen" up as they break in (although I find the TI's tend to stiffen up a touch). Anyway.... so far, so good. Rehearsal tonight. We'll see how it goes!
