Up until now, I've used HD lights on my 2014 K24 alone, which has always been a winning combo for me. I've used standard lights on my other guitars. My 2020 714 has been such a beast - lots of volume, sustain but with still more overtones than I'd prefer, especially on the treble strings. Well, I recently strung it with HD lights, and now I can't put it down! It has become a perfectly balanced guitar like my K24 and my 2019 614. As has been said before, a change of picks or strings can make a significant difference in tone, before one starts messing with other mods to improve the playing experience. I just hope that Elixir continues to offer the HD lights, because I'm sold on them for at least two of my guitars at present. Just passing this along....
