What kind of strings should I be using on my new sevenstring when I got it in Drop A? Does it work with the standard ones ?
yeah, it works fine with the standard ones.
It's kind of like going from standard to drop D on a 6 string. That B sting should be able to handle A fine.
Drop A? My six stringer is in drop A, you should go for drop E or something.
i rarely use 70-13 gauge because i rarely use drop a on my 6 strings.
You'll be fine, only dropping one string down a step.
