Hello. Yeah, it's me again. I'm a baritone 6-string lover. I've never owned a 7-string of any kind before.
The answers to these questions are probably obvious, but I haven't been able to get a solid answer on either:
1) What's the true advantage to owning a baritone scale 7-string vs a standard scale 7?
2) What would you, personally, tune a baritone 7-string to?
I know that typical 7 tuning is like my bari but with a high E added for extra lovin'
B E A D G B E is typical on a 7 I would assume.
What do you tune a bari 7 to?
I tend to keep to standard tuning, so I can only speak to your first point, but the big benefit is increased string tension in the bass. It's really noticeable, too, and has a fairly significant impact on your overall sound. If you're primarily doing rhythm work, they're excellent guitars - the trade-off is that the treble strings become tighter, leading to increased difficulty doing bends (unless you're, you know, a man), longer reaches between frets, and a more piano-like timbre in the high register.
You really have to play one to know what they're like.
Or just join the fanned-fret master race and be done with all those weak-ass scale length arguments for good.
