You wanted the best, you got the best
These are the black magic of the guitar world. They’re dirt cheap, they don’t make any sense, and they can handle tunings as low as C# standard even though they’re .10’s. And I say ‘handle’ because these are somehow able to stay taut at places where other strings of identical gauge would become noodles. I broke one of these trying to tune it a half step over standard, which is pretty typical for me when I’m using light gauge strings. BLACK. MAGIC. This sounds kind of negative but these are my favorite strings in the world. They shine like bridge cables and the tone is diamond hard. I’ve been only using Dunlop heavy cores on a few of my guitars for over two years, now. Get a set, tune below standard, and enjoy your stable intonation on those insane two-step bends. I put these on my Mustang, half a step down, and if you want to do pull-offs until your fingers bleed, by god, that is the way to do them.

Good electric guitar strings, metal a.f.
Bang your head with these great strings specifically catering to the budget metalhead. They are totally on par with other brands that cost 3 times the price . Nothing to complain about at all, and they last a while and I rarely break one. Great value for a gigging guitarist that likes the feel of fresh strings but doesn't want to spend a bunch of unwarranted cash.

Made for Metal!!!!
These Strings are rather unique to me. I used them for about a month and I found that they stay in tune well, but they have a really bright tone and work well with higher gain mid scooped Metal. I don’t play that style as much as more mid pushed so the brightness was tough to overlook. If you are looking for a String that is excellent for low tuned Metal, these would be a great choice! They are purpose built for this in my opinion. The other thing I would say is these Strings are really durable! I felt very confident bending them up a whole step!

Quality strings
I have yet to break a string with Dunlops. They're strong, feel smooth, and last for months. These Heavy Core strings sound loud and have a big midrange tone. Compared to normal Dunlop strings, they have a little more tension, and this is good because lower tunings don't sound floppy. They're still as comfortable to play as the normal strings too. I recommend these strings for rock and metal players, but they're also good if you just want a louder and present sound.

Amazing strings for metal chug.
Sound great, clear but warm. Let's the midst and highs cut through. Great sustain. Take lots of abuse from the Floyd, and still hold tune. Last a while as well. Highly recommend for low tunings.

Excelente sonido y relación calidad-precio
Muy buen sonido y sensación. Recientemente mandé a servicio mi PRS SE Paul Allender, la cuál tengo afinada en D (un tono completo abajo) y el resultado es bastante satisfactorio, el sonido en las cuerdas bajas se siente lleno y bastante cálido incluso con un fretwrap, mientras que las cuerdas altas tienen brillo y la tensión adecuada. Hasta ahora la afinación se ha mantenido excelente, aún abusando del trémolo y haciendo bendings y dives. Hasta ahora mis cuerdas favoritas para afinaciones graves en mi PRS.
