"Good Strings"
Your brand of guitar strings doesn't really matter, as they are only a few locations, which manufacture all of the brands. But the price of the strings on Amazon beats any music store.

"Mandatory Read"
Take this to heart. I have been playing for 16 years this Christmas. For the first seven years I experimented with different brands and gauges. These were the strings I settled on after all that experimentation and I have never looked back. Slinky 9's are ALL I have bought for the past nine years. There are two types of electric guitar strings: Expensive and cheap. NEVER buy cheap strings. They sound too bright and about one out of twenty will break when you wind them up. Expensive strings are a little more complicated. The durability factor is much better with expensive strings. About one out of eighty will break. The difference between the expensive brands is in the sound. Some are "tinny" or bright. Some sound like bass strings tuned way up. With that said, Ernie Ball Super Slinky 9's have what I call a "V" voicing. It's like they have a little equalizer built in set to a good rock setting. You know, boost the mids and highs and roll back the mids. THESE... are the only strings designed specifically for rock/metal/southern rock/progressive heavier jam bands/etc. Period.

Man... I sound like a commercial. It's because I am passionate about these strings.

"They are ok"
They are ok because one of them broke the first day but i think it broke because my guitar was messed up that day when i put them on but other than that they are ok.

"Gnarly strings for a tubular price."
These are the standard strings I've been using since about 2000. And after going through only 4 pairs since then, I doubt I'll be changing brands. Especially at this price. Just look at that. In just about any store they're up to 3 times as expensive. Don't let the price fool you. Sure, there are some strings around 20 bucks, but that doesn't mean they're better. Ernie Ball is one of (if not, the) top brands when it comes to musical instruments and accessories. The sound quality and tone with these suckers is phenominal. You can bend, whammy, slap and pluck these things as hard as you can, and they won't break. In fact, I've been on the same set of strings since about October 2003 and they're still working like the day I put them in.

There isn't a whole lot to say about strings. I mean, they're what you need to play the guitar and that's about it. These work well, therefore, they're good. Nab a few extra sets of these while they're so cheap.
