Re: Baritone string gauge?
^ in the ERG forums, a lot of people gripe about standard strings not being long enough, or having tapers that don’t go past the nut. That’s typically on really heavy strings, like well over .070”, but that’s a good warning.
At that scale length (and anything over 26.5” to my ears), your tone is going to be way more bass than guitar or even baritone. Trying to get a string gauge with adequate tension that still sounded like a guitar on a 27” 8 or 7 string ultimately proved to be a failure to me. I’m much happier with 25.5” guitars tuned down, proper intonation all the way up the low string be damned.
That said, embrace that it isn’t gonna sound very guitary and it should be a fun instrument.
