Great strings

I have these on my Martin 000-15M and think they sound great. The added durability and life is nice while still sounding great. Has been my go to string on all my other acoustics as well.

Great sound!

These strings came stock on my HD-28 and they sound great. I see the reviews about them being tinny and it’s to be expected, they’re new strings. However, once they mellow out after a few plays they sound fantastic.

Martin really did a great job with these, I have them on all of my acoustics. They do last far longer than any other brand of stings I have used. Satisfied customer.

Great Strings

I have a PRS A10e all mahogany guitar that has always been strong with D'addarios. There were some tonal qualities about this specific guitar that I wasn't totally in love with. There seem to be some low-end overtones that were a little overpowering and distracting, especially when miking it up for recordings. I spoke with my local guitar tech about the guitar when having it set up and he suggested trying these Martin strings. I wasn't fully aware at how much different string brands can change the tonal characteristics of an acoustic guitar. For this specific guitar there was quite a change in the low end characteristics. The strings sound bright but balanced, and really rounded off the low end. The woofy 200Hz overtones are vastly diminished giving the guitar a significantly more pleasant and balanced sound. I could totally understand where for some guitars this might not be a desired effect, and all in all will be different from guitar to guitar, but in my case they made a guitar I wasn't super fond of a favorite.

Current favorite

Tried these out on my always-out-of-the-case Yamaha- was shocked by the playability and sound. This was months ago- have bought sets. both light and mediums for my Martins and a replacement set for the Yamaha- still not needed. They stay in tune and don't seem to deprecate in sound. Ny past go-to has been Elixir Nanos. Will continue to compare back-to-back, but these are really very, very impressive.

Martin Authentic Acoustic strings

They seem much brighter and ringee then the lifespans they replaced,maybe they will warm up when they play in .
