D'Addario Electric Bass XL Nickel Wound 6 String Bass Long, .032 - .130, EXL170-6star rating 5Greg CriderJuly 25, 2010I've used these strings for decades in their 4- and 6-string versions. They have a good, balanced sound with plenty of highs and controlled lows. No other string that I've found lasts as long, keeps pitch as well, keeps as consistent tone string-to-string, and is as easy on the frets (for round-wounds, that is). I try others, but I always come back to these. My next step is to try a .32-.40-.60-.80-.100-.125 custom set.
