Review: Some really good strings - Context: I'm an extremely, extremely mediocre player with under 15 years of playing. I primarily play dropped tunings and recently purchased a 7 string so I decided to give these a shot. The strings on the guitar were an expensive brand so I was weary about slapping these on but right after some flubbing around I dialed in my tuning with the Stringjoys and I immediately noticed a difference in tone. The strings beforehand would produce a noticeable hum and buzz when idle and during play. The Stringjoys are quiet, I can bend as needed and they'll keep in tune. I'll be these first to admit I am horrible at restringing so having a set that withstand my heavy picking is honestly a little weird. The guitar I'm using is a 26.5" length bolted on neck so that might be helping a bit. I noticed zero slack while playing Drop F. I used the 11-70 set and found that my tuning pegs and nut didn't mind the extra girth, unlike your mom. Anyway, intake my word for it or don't but these strings surprised me and fit my needs.
Review: Best strings I've played, worth the money - I've been playing a lot in the past week since these arrived and I couldn't be any happier. As soon as I started playing, I knew I made the right choice. The strings have stayed in tune even through heavy usage. The bottom end is perfectly capable for drop tuning and it sounds amazing; there's no looseness or string buzz in the lowest string either. I love how crisp and clear the strings sound, especially the higher end strings. The strings also feel great overall. The perfect balance of light and heavy for my fingers. All in all, I'm very happy with everything from playability to sound to feel. They're the best strings for my extended range guitars that I've used thus far.
