I'm speaking to those primarily with the Quantum neck, but feel free to chime in if you have the Genesis. I've read, in several places on just random reviews, that many Modulus users prefer the stock D'Addario strings to anything else they may have used. I'm assuming the nickle strings help tame some of the natural brightness that comes from the neck. I just changed the strings on my Q6 for the first time because I had gotten a good deal on some Elixers. While the tone is different, I still have that same even tone all across the neck. All that has really changed is that the "brightness" of the tone has become more dynamic. I think I've liked this change for the better. Simply regarding what I've heard, does anyone else have an opinion on them?
