Electric guitar players will find that these strings are a quick tune up that allows your old acoustic guitar to be played much much much more like an electric guitar. Transforms the stiff acoustic into a softer playing instrument much more compatible with electric playing style.
Also the sound of these rock / blues strings is a little different. The phosphor ones might sound a little soft, but the 80/20 bronze are distinctly brighter sounding on my guitars.
My Yamaha parlor’ish csf1m crimson red small form acoustic guitar sounds great with these strings: bright, loud, clear, very musical. The csf1 crimson red is a little known jewel in the distinguished Yamaha acoustic line up. It also comes with a very high class sturdy Yamaha gig bag. Awesome gig bag.
My Yamaha Ac3r stage acoustic is much larger and this also sounds great, bright, clear, and resonant with these strings and it feels a lot more like an electric with the nice profile Yamaha neck. Nice slim neck. It is a rocking combination, especially when amplified.
Amplified these strings actually come into their own best realm where their characteristic feel comes into play. The sound is awesome, enhanced by the easy bendability and sensitivity.
Unamplified the bronze version sound great to me during leisurely playing. I am accustomed to the sound and feel of these strings.
These strings are extremely resistant to breaking under very very energy intense playing. Ernie Ball is known for making nearly unbreakable guitar strings.
