I change my acoustic strings so infrequently it's hardly the sort of thing I feel comfortable mentioning in polite company, but I'll say that after playing martin marquis red label for many years, I couldn't get 'em anymore. And then it was whatever was on sale cheap. But I've finally seen the Elixir light, and I feel far less guilty about how long I often go between changes. I find the Elixirs bright and balanced and harmonically complex. And this is on a mahogany Martin DM dreadnought, which ought not to be so complex, what with the laminated back and sides; but there you go. It ain't rosewood or koa, but it's surprisingly rich with the Elixirs.
