Demanding musicians need long lasting & great sounding guitar and bass strings.  I tried many different brands before finding the right strings for my needs.  As a steady musician - practicing during the week and playing energetic gigs on the weekends, I needed strings that sounded great, and ones that lasted a long time.  I would sweat profusely on my strings while jumping around onstage under the hot pulsating lights.  The sweat would really dull the sound of my strings.  As I was complaining about my problem to a band member, he introduced me to a new EXTRA LIFE COATED string.  These coated strings are made especially to protect against damaging substances such as perspiration, dirt, humidity, and "acid hands."  I soon found out that they did last longer than other strings and they sounded awesome.  They also come in cool colors: Peacock Blue, Red Devils, and Black Beauties.  I said WOW! - Strings that look cool, sound great, and last longer than any string I've tried before - That's why I'm now advocating DR brand guitar and bass strings at great prices. You can get these strings at my ebay store: Da-Vez Music
