PS: What do you suppose they'd sound like on an electro-acoustic?
That depends on what you mean by electro-acoustic, I suppose. I'm not sure how they'd work on a mainly acoustic guitar with a piezo/other type of pickup, but I've seen quite a few Taylor T5's and Michael Kelly Hybrids with electric strings.
A friend of mine used to collect nasty, used electric strings and string an old, no-name acoustic with them. That certainly made for a "unique" tone, but that's probably not what you're going for.
Anyone else have any idea of how electric strings would sound on a more traditional acoustic/electric?
King Harvest has surely come.
I think nice, shiny new nickel electric strings give a very bright sound. I like it.
Nickel wound strings ("pure" nickel, not the nickel plated steel usually called "nickel" now) used to be the most favored strings for acoustics, I understand, and the phosphor bronze ones only go back maybe 50 years. Brass was the other, cheaper option to nickel. (Still available as 80/20, sometimes also called "bronze" but it's really brass.)
