Maybe a contrarian post, but I stopped using Elixirs years ago. I was constantly snapping G and D strings, always at the nut or bridge. Not a problem with the guitar, it was the same across half a dozen instruments, and friends had the same issue. Elixir weren’t interested when I complained. Then there were the restrictive trade practices. Elixirs here in the UK are ridiculously expensive, and Elixir don’t allow their US dealers to export cheaper strings to the UK; price fixing.
Then there’s the tone. Like all strings, Elixirs sound fine when new and played in for an hour or so. After that, they are just ‘ok’, but they stay ‘ok’ for longer. When I was gigging regularly I needed the great tone for each gig, and that meant string changes at least every other gig. With Elixirs, the cost was prohibitive, and the so-called advantages of coated strings were lost.
I’ve gone back to my old standby; D’Addario Phosphor Bronze, bought in bulk from Strings and Beyond. Cheap enough to not worry about frequent string changes, no breakages, great tone that lasts longer than expected, especially if I give them a wipe before putting the guitar away.
