I enjoy work, but not when I’m playing guitar. I know what you meant - 9s or 9.5s are fine. After watching the video that was posted above and listening intently with headphones I’m convinced that the lighter strings actually have more clarity. The last part of the video where he A/B’d the recording with 12s versus 8s was an eye opener. While the 12s sounded good (he’s a great player after all), they actually sounded muddy compared to the 8s. Anyone who thinks they’re getting more clarity because they’re using heavy gauge strings is absolutely mistaken. My friend, who’s been playing as long as I have (roughly 58 years), uses 8s and gets a great sound; he was a west coast session player in the mid-sixties, toured with the Jazz Crusaders, and his band opened for Jimi Hendrix on the West coast a time or two. 8 gauge is too slinky for me but works for him. I’ll never go back to 11s!
