Don't get it. Why would someone want a 7 string? Lets make a 14 string whilst we're at it. Or maybe a 9 string, or maybe a 27 string......
Awesome guitarist though. Seen him up close and personal a couple of yrs ago
That puts Rick Nielsen's quintuple-neck guitars to shame!
No 7 String but he did rock the baritone hybrid for Isolation.
I don't know why he would use a baritone hybrid, "Isolation" is just in Drop C. I would see for maybe one of the songs where he's tuned that E down to Ab
He had said that the Baritone Hybrid was more for his solo stuff in Drop B.
He probably just used a regular stoptail version of his Tremonti model for "Isolation."
A great deal of the AB material, especially from Blackbird and AB3 is drop B though and he's using his black signature model with Another Animal sticker on it for those tunes
