Ernie Ball Super Slinky 7-String Nickel Wound Electric Guitar Strings - 9-52 Gauge

Perfect for standard tuning. Even half step down is good. I'd give five stars, but the low b really needs to be just barely bigger... like .54 instead of .52. I'm a firm believer in getting the smallest string that doesn't turn into a rubber band at your tuning. Unless you're putting so much distortion that it eats your tone up anyway, it just sounds better. The .52 B is perfect for standard tuning, but drop A, while doable, is just a bit too low for that string size. Drop Ab is definitely past what I'd say for a .52. Considering Drop A is to a 7string what drop D is to a 6 string, I thinks its a bit of an oversight. And its really only just barely too small. I'd bet a pretty penny that a .54 would be enough to make up the difference. And by time you want a drop Ab tuning, you're probably better off with the regular slinkies anyway.
