Daddario are a good alternative to other branded strings.
I believe for long time I used Ernie ball strings but one day I started trying these Daddario and surprisingly I found them very nice. Since then I use them reguarly. The sound is fitting my needs and even if the guitar I use atm has cheap pickups mounted, these strings have been able to deliver also a bright sound when needed. Lasted long and quite resistant as well to some sweat, when playng hard on live stage under hot stage lights. No oxidation, although using a strings cleaning product help them lasting longer, without losing their qualities. Go try yourself. Cheers
If someone told you that bigger string gauges sound better or stay in tune better they are full of it. That is a myth. Bigger strings make most 7 strings sound muddy and you lose note definition. I have these on my Dean RC7x with a 25.5" scale length, I have it tuned to B Standard for 7 String (B E A D G B E), just like a 6 string with 09 to 42 strings, and an extra 54 for the Low B. I play almost every day for at least a half hour to an hour. Only gotta tune up about once a week. These strings stay in tune well, are very crisp, and if you clean them (which you should with any string) they should last about a month. Better and more affordable than most of its competitors
