Weather you're a professional looking for better feeling and toneful stings that hold tune, or a beginner that doesn't know where to start, THIS IS IT! The good news is that when it comes to gear, so many things are incredibly subjective and different, well these aren't. These are the best!
I use these strings on all of my guitars, and have now for 6 years. They have incredible stability, tone, and playability. All of my guitars are equipped with Original Floyd Rose tremolos. I am not lying when I say that I can NOT remember the last time I broke a string, or if I even have broke a string since using Dean Markleys. I do remember breaking strings all the time with D'Adarrio strings, and having tuning problems with Ernie Balls, even though I am throughly trained and experienced with setting up and maintaining a Floyd Rose. It's just a simple fact that that these Dean Markley Signature Series, although surprisingly cheaper in cost than most, win in EVERY category when compared to any other string from any other string manufacturer in my experience.
I play everything from David Gilmour and Alex Lifeson, to Trey Azagthoth styles on the guitar, and can NOT remember a string breaking once since switching to Dean Markley Signature Series strings. Bending all day long, tapping, digging into full on chords, and bottoming out the Floyd Rose does not effect the tuning or tone of these strings. I give them a little wipe before and after playing, and they're like new. I change my strings one a month and play in a performing band that does 3 hour sets. Now given that I do use different guitars, one month is a long time for a string to keep tune, feel, tone. These Dean Markleys do every time.
For the price that Musicians Friend offers, c'mon! If I had the money to, I'd buy a boat load of these and throw them in the freezer. Instead, I just buy 10 at a time!
