Got my first set of flats, ever, today, but first a little background on what I have been using. I started learning to play bass around age 11, way back in 1977. All I have ever used on a regular basis has been Ernie Ball Slinky (nickel wound) sets with a set of GHS Boomers thrown in there a time or two. In 2001 I got married and well, bass playing, along with my Carvin LB70, went out the window, soon to be followed by the marriage in short order. Over a decade later in early 2016 I traded a Peavey 1820 cab for a Cort Curbow Signature Series bass. I immediately put a set of Ernie Ball strings on it and started playing again, for the first time since late 2002, early 2003. Fast forward to August 2018. I started gigging with the Cort and decided I had to have something better and bought a brand new Ibanez SR400EQM strung with D'Addario XL nickel wounds. Then two weeks ago I bought an old Epiphone P Bass ($65) with crap pups and electronics. Replaced all that with EMG GZRs. And put on a set of DR Black Beauties. They sound a little "tinny" to me, but with a little wear that will probably work itself out. Then a week ago I bought a 2012 Ibanez SRX2EX2, again like other Ibbys, it had nickel wound D'Addario XLs. I have absolutely fell in love with this bass, but the strings are a little worn so I decided to experiment and go with "flats" which brings us to today... I bought a set of D'Addario XL "Chromes" 50 - 105 gauge flats. Now it's really too early to tell, but... I sat down, took off only the "E", restrung the new "E" flat on there, got it tuned up, and plugged it in just to get a taste of what it would feel and sound like. All I can say is wow! So time to get off TB and finish stringing her up. As soon as I'm done I'll sit down and run through a few songs and see how they really sound. But I have to say I was impressed for just a few notes and one string. If my first impression is going to be the same for the rest of the strings, then I'm going to be a very happy camper. Hate that I've waited 40 years to try a set of flats. I guess sometimes an old dog can learn new tricks afterall.
