For years in the past, when I only had my Strat, I read guitar magazine and early internet posts about string gauge. Bigger strings mean a bigger sound. Gotta go big. SRV used 13s, ferchrissake! As a result, I put 11s on my Strat, and used 11s for years. In 2015, I bought my Baja. At that point, I was getting back into playing after years of playing intermittently at best. I got a set of 10s on my Baja and put 10s on my Strat. After playing a few guitars in shops that had 9s, I wanted to try 9s on my Baja, so I put a set on. No go. It was then that I noticed the Baja’s neck was very flat with almost no relief, and the truss was all the way loose. 9s just rattled too much with my heavy-handed playing, which I was / am also addressing. How did I fix this? I put 11s on the Baja for a couple years to help “pull some relief” into the neck. I probably should have gotten a fret level and crown and maybe a neck shim, but the 11s seemed to work well enough to resolve the neck issue. I then went back to 10s. The 11s were not bad; I could lower the action a bit, and they felt very similar to 10s until you did bends. I recently bought a new Tele – an American Professional II. It came with 9s. I like the 9s. Sure, I am adjusting a bit to not pulling them sharp, but the feel is so much easier. I have also been seeing a lot of internet examples of how lighter strings “sound bigger”; I don’t think the string gauge makes that big of a difference (at least for me) in sound, so no big deal. Bends are so much easier, and easier to control. I just ordered a three pack of 9s; I am going to put 9s on my Strat as well; the setup changes will be easy. I will leave 10s on the Baja and decide if I am going to keep it. I think I'm a 9s guy now. I have to drop that association of myself with big strings and old internet blather.
