Bah. I hated this conversation over at www.sevenstring.org
Wanna hear something funny?
1.) This Optimum String Guage idea is pure BS.
2.) I still use something pretty close to what he considers optimum, a set of 10-48's with a .68 low B, and I'm contemplating stepping up to a 10-52 with a .68 B. I've been stringing this way for years.
Here's the thing, thje whole premise of OSG is that there IS a right and a wrong way to string your guitar. That's utter crap. You know why I use such a heavy B string? Because the way I pick I always seem to hit the low B quite a bit harder than the high E. For ME, and for the way that I PERSONALLY play, I can't get away with a .52 because every time I hit the thing you can hear it pull sharp and then settle back into tune (as a vibrating string is technically being stretched by the amplitude of the vibration - think trig - and thus goes slightly sharp, the wider the vibration the further sharp), sometimes as much as a quarter step. It just doesn't work for me, due to the way I pick.
I don't understand how someone can play a .52 or a .54 low B in tune under a .09 (as tension is in many ways relative), but that's just because of the way I hit the strings. For someone with a lighter attack on the low strings, this makes perfect sense.
Anyway, it's crap because it's not 'optimum,' just different. Could it work better for you? Quite possibly, and it's certainly worth a try upping your bass guages a bit. Will it make you a "better" guitarist, magically? Of course not. It may make you more comfortable while you play, however, and for that reason alone it's worth experimenting.
If you play 9-42's or for us seven stringers 9-52 or 54's simply because that's what you've always done, then of course it stands to reason that spending a few weeks/months experimenting with different sets will be beneficial for you. But there's no RIGHT way, just what's right for you.
The dude from Zachary Guitars is certainly an interesting guy, and he has several interesting ideas. But "moderation" has never been his strong point - he's a total extremist, and there's no middle ground, and this is a classic example of this.
