Tired of changing strings?
I started using Elixer nanoweb custom lights on my acoustic guitar 7 or 8 years ago. I am in a country band that plays 2-3 show a week. Sometimes I will also do an occasional acoustic show on a weeknight as well. These strings are a good bang for the buck.
That being said, I can usually play on a set of strings before they start losing tone for 4 to 6 weeks before changing strings. The key to keeping these or any strings sounding "alive" is to clean each string with a dry rag before putting up your guitar after every ( and I mean every) you play. These stings will start to look worn long before the tone starts to go away and you know they are done when you start having to tune after every couple of songs.
Overall, I highly recommend these strings both the acoustic and electric version. Been using them for years and have tried some others over time, but always come back to these.
