Question about string separation

[Brad Malone]

I have a Mullen D-10 and the string separation at the changer is 5/16" and at the roller nut 4/16". What is the string separation on 12 string pedal steels? Also, what is the ideal string separation for best tone?

[Jim Sliff]

I don't think there is any exact standard. Previous discussions (you could use the search function and find several threads) seem to indicate there's not any consistency - they are all close, but not exact. I recall someone saying Sierras were more closely-spaced than som others, but I could be wrong.

As far as tone goes, string separation is irrelevant....well, as long as they're not close enough to hit each other.

Here's one for you Blanton guitars do not taper at the roller nuts,They have the same string spacing at the bridge.It makes it a lot easier to get in between strings on the first fret,also less bar pressure is needed to get a clean"no buzz"tone.

Most steels are 11/32" at the changer.

Some 12 stringers are 5/16", to reduce axle flex.

My Denley is 3/8" at the changer.

1/4" sounds about right for the nut.

Wider string separation effects the magnetic signal somewhat, giving a more distinct tone with less blending together of the notes. Try comparing a six string lap steel to a 10 string, the tone differential is not only caused by the different impedance's, the picking is also more positive and solid with more space to play with !!

Baz - I don't disagree, but with most pedal steel strings differing in spacing by 32nds of an inch, it's not really significant...so in the context of the question I was just trying to give a relevant answer.

When you get to different instruments like lap steels, yes, it's different.

Thanks Basilh, that is what I thought I read somewhere but you said it better. String separation does have an effect on tone.
