Daddario EXL150

The "Daddario EXL150" 12 string electric guitar string set in nickel plated steel, these were supplied from the factory with my Danelectro DC59 twelve string, they sounded great and the factory setup, (was probably the best I have had on any new guitar !!) so I was happy to find the Daddario strings are cheap and readily available.
The set are made up with plain and round wound strings, gauges are 010/010 - 013/013 - 008/017 - 012/w026 - 018/w036 - w026/w046.
These are fairly "bright" sounding strings when new, I find they take a couple of days to stretch in and for the sound to dull a little, after that they sound great - clean, clear and stable, with the little Danelectro they give that classic 12 string jangle, full, crisp and articulate.
I use Elixir nano webs on all my six string electrics so I'm used to strings lasting a long time, the Daddario are obviously not in the same league but they do last quite a long time and certainly for the price they are quite brilliant.
I would find it hard to pay three or four times as much for the equivalent set of Elixirs when these perform so well, I think the only reason I would try an alternative is maybe to try a set of flat wounds some time for a real vintage tone but until them I'm more than happy to stick with the Daddario's.

I use them on my Epiphone G1275 and I can say that they are indeed a really good sounding pack of strings. They preserve that sound for a really long time and if I had cleaned them properly I could have still been using my old ones.
They aren't of such expensive brands, but they are still really good for their price. And because they are a 12-string set they aren't going to be prone to breakage, because most of the times strings break on bending and how often are you going to bend while using a 12-strings guitar? I haven't had a broken string of that pack.
All in all, Daddario EXL150 are my go-to for 12 strings, because their sound, intonation and overall quality surely meets my needs.

I've been using these strings on 3 different electric 12 strings for a few years and they really do the job - light enough to make things easier, but tight enough to avoid being flappy!

The 3 guitars I use them on are all very different, with different scale lengths and feels. In all cases these strings deliver great sound - nice and bright with just the right degree of 12 string sparkle.

D'addario quality is good too - High 3rd strings can be pretty flimsy but I never have a problem with these snapping. Intonation and durability are great too, The strings last a long time and keep their tone and intonation well if you keep them clean.
