More range for a vague reason. If you like heavier, down-tuned music, you can create it with a better voicing.
If you just wanna try it and don't like the extra string, you can set it up as a six string.
It's versatile - for demos and preproduction, I use my seven string for the bass track and can accomplish a good tone with guitar processors.
steve vai use it
Love 7 strings. Wish ESP would bring back the Ltd f 7 string or make an ax model 7 with a neck through body & EMGs
Yeah, it's pity, that they discontinued some 7 string models now (for example EX series). I'm really happy, that I've bought my 7 string EX before it happened.
yep, Im on the 8 string kick now. You can go low and nasty but still play in standard. best of both worlds
Yes, more options for songwriting and interesting harmonys, plus it sounds brutal.
