I use Ernie Ball strings on all my guitars: I use .10-.46 for standard E tuning, .10-.56 for 7-string standard, .09-.52 for ASP 7-string tuning (the guitars are basically tuned up a whole step with a drop B: 1F# – 2C# – 3A – 4E – 5B – 6F# – 7B) and we add a .70 for the 8th string tuned to F#.more
These strings are really good for an overall bright or deep sound. The variety allows for a lot of power within the strings and gives the player a lot more freedom to explore different sounds on a guitar.
These sound great on my flying V guitar, which is actually a cheap Harmony that I painted and modded with DiMarzio humbuckers. That thing wails, and these strings add some nice beef to the power chords. Definitely recommended for all sub-genres of Rock.
