Stepped / Tapered strings. Why?

[fretmeister]

What is the purpose of tapered low strings?

It seems very odd to me. My basic physics seems to think that changing the diameter of the string so drastically must arse-up the vibration.

What say you?

Well given that the first inch or so of string coming over the bridge and the nut is almost redundant in terms of vibration then I suspect that a tapered string will make it a lot better.

Taken from the FAQ at www.professorstring.com:

[b]"Why are some bass strings tapered?[/b]
There are two popular theories that suggest a tapered design is better than non-tapered. The first theory suggests that having too much mass at the string's fulcrum point (the bridge saddle) effects performance, particularly stability and clarity. In theory, tapering eliminates the problem. The second theory suggests, by eliminating the windings from seating on the saddle, tuning performance can be improved. In theory, tapering also eliminates this problem. Is any of this true?...you be the judge."

A tad inconclusive I have to admit! I don't use them regularly myself but on the occasions I have I've found the string to ring a bit more clearly than non-tapered. Perhaps something to do with the tapered part giving a cleaner break angle over the saddle.

I get all my strings tapered on both my gigging basses... if only to sit lower on the saddle.
The single core might be a bit more exposed and breakable...but not if you string it correctly.

Certainly for a 120 gauge and up... less is more, IMO

Mate my super heavy strings much easier to fit into standard bridges. The extra flexibility at the bridge contact point also can reduce inharmonicity a bit, bit more like a piano string.
