Gauges 11-15-22w-32-42-52.

These are the very same guitar strings that come on Gibson's famous J-200 Jumbo acoustic. They have an excellent ringing attack and presence, and will give your guitar a responsive voice that cuts through, thanks to the special phosphor bronze alloy. And they're vacuum sealed for freshness.

All Gibson strings are bench tested and builder approved to bring the best sound possible out of your instrument.
