I believe this has been discussed here before...however, it's a good discussion to have and always interesting to read responses. What strings do you use and why? I bought a strat about 4 years ago from a guy in Cali...he threw in 12 sets of Fender Super Bullets as a free bonus because he didn't like the strings...At the time, I was using Ernie Ball 10's. I decided to take the "Sting Challenge" I took all those Super Bullets in to a guitar store and the guy let me trade them for all different kinds...D'Addario's, Ernie Ball, Blue Steal, Dean Markley, Boomers, etc...I tried a ton. Long story short, I came full circle back to Ernie Ball. I really like the longevity of the string, and the bright clean sound it has. I use 10's on my strat and 11's on my tele. I like D'Addarios too, but I have really sweaty hands and find that Ernie Ball seem to last a little longer for me. For acoustics, I LOVE Elixors (sp?) I tried them on my electric and I went through a set after a 2 hour gig, so I didn't like them a lot...anyway, I'm really excited to see all of your responses!
