Andy, what string spacing would you suggest with a 57.5 - this is a BIG guy. And what at the bridge. I had him finger a four string C chord, to see if his left hand could be clean, and it can't. He touches adjacent strings. I've also asked him to check his span. Even though it's a far from perfect test, it at least gives some rough guide. Because besides the 57 or 57.5, I'm thinking maybe 660 or 664. He's playing a 650/52, and I had him finger F on the first string and try to finger A on the fifth fret. He can get it into the early part of the box, so I suspect at least a 660 would work. I wish I could see him in person.
Hmm, just this moment, as I was writing the last sentence above, I had a thought - maybe I could watch him on Skype. It's better than nothing. I'll ask him.
Probably something like 49 at the nut and 62 at the bridge. Or just recommend he pick up the guitarron
Hey Andy - that Guitarron is not a bad idea - especially when I tell you his span - it's almost ten inches. I told him how to measure, and I just got back the stats: from fingers One to Four - Seven and a half inches. From pinky to thumb - Nine and Seven Eighths.
Would love to hear from more of our luthiers on this, given these figures. I'm going to see if he can Skype, and that might help, but in the interim would any luthier here have any ideas or comments given that span - both on nut and scale. The problem of course is that I don't want to see him lose his money. If we don't get it right he obviously can't return it, and it's basically zero chance of selling it.
My immediate thought is to make an extra wide fingerboard, even more than has been discussed, so that there would be room to widen the string spacing if necessary. But I guess there is just so wide it can be made and still be practical and playable.
And 660 seems like a bare minimum - I hope I can see him on Skype with a 650 in his hands. It would give me a better idea.
Appreciate any thoughts, comments, ideas. Short of converting a cello to an arch top guitar.
