The guitar strings are the first strings I played after I switched from DR Strings (after 13 years)..
They sound way clearer and brighter, punchier. They just make the guitar sound less dull.
I mostly play Drop A on a 7 String and use those strings, I play hard and normal guitar strings (ernie ball etc) ripped very frequently.. This stopped with DR and now continues with D'Addario!
The sound lasts way longer than the DR's too.
Give them a try if you enjoy heavy sounds but like to keep it clear.
I play a Shecter KM-7 MK III in Drop A or G# tuning (Periphery, Merrow, Conquering Dystopia but also stuff like Carcass, Entombed and similar)
