It took me more than a decade to find bass strings that were both long lasting and great sounding.  After many years of playing gigs energetically on stage under hot lights, I became frustrated after buying strings that only sounded great the 1st or 2nd time playing them.  After sweating through a summer gig, where sweat was poring off of my body & onto my bass like a waterfall, my strings became  dull sounding very quickly.  They lost that new bright sound after only one gig.  Finally the DR company created Extra Life Coated guitar and bass strings that not only last up to five times longer than most strings, but they sound outstanding too! But that's just the start: these Extra Life strings are color coated so they look awesome too!  They are available in red, blue, black, hot pink, and green.   I always loved the sound of DR strings, but when I saw that they made strings that last long, I jumped all over them.  Now as the owner (David Zanoni) of Da-Vez Music I endorse these strings because I believe in them 100%.  So browse my store and pick out the strings that fit you the best !  Da-Vez Music
