I use these on a Stratocaster. You will need to add extra tremolo springs if your guitar has a tremolo system like a Strat since these strings will add stress. I used Pro-Line brand and in five minutes had the tremolo bar back in place. You may also need to adjust your set-up if you standardize on these. That said, these are very good strings. My Squier Strat is now jazz ready. These strings make the guitar easier to play in tune when forming chords, and it needs much less re-tuning than with lighter strings. These are heavier and less bright than most pop-rock strings. They are also less affected by string-pull and I raised my pickups to compensate for the loss of brightness somewhat. Since they are flat-wound noise from sliding your fingers is eliminated. I recommend these for Jazz and Standards of course, but you may like them for rhythm with any style of music. I used them to accompany a solo clarinet for a “New Orleans Night” show (just me and a the clarinet with some vocals) and I could not have made a better choice.
