I've been using the
WebStrings electric and acoustic sets for about a year and a half.
Reviews:
"Memphis Electric" nickel-wound 6 and 7 string sets, 10-46 and 10-56:
I swear, D'Addario makes these for them. The windings and overall "feel" are virtually identical. Tonally, they're just like D'Addarios, as well - they don't have the greatest initial "brand new" bright tone, but they're very consisten for a long time. I haven't had much issue with breakage, either.
"Portland Acoustic" Phosphor Bronze:
Deep, sweet and dark, just like you'd suspect. Sound just like the D'Addario PB strings. Good life, too.
"San Diego Acoustic" 80/20 Bronze:
I haven't used the D'Addario version of this string, but these are very chimey and bright, and project like a mofo. I played a 3 hour gig on them two weeks ago and they still sound brand new.
Overall, I've been really impressed with everything I've tried from WebStrings, especially given the ridiculously low price. They ship fast and generally have what you want in stock. They messed up and sent me four sets of 11s once, and they sent out the correct 10s the day I emailed them, and had me keep the mistake!
