I suppose I’m turning old when I’ll have to settle for these for the price that would’ve bought me a set of the much better D’Addario classical strings not that long ago, yet moving on…
These strings by Martin are alright. Not bad by any means, yet not brilliant either. It clearly shows these are likely generic strings Martin slaps their brand name on, though, as there’s no particular quality or differentiating aspect about them that sets them apart and make them a solid choice for any other reason beside the price (well, perhaps apart from the fact they have ball ends if that’s something you need).
They sound okay, but not bright not particularly vibrant, either. They won’t bring the best tonal properties of your guitar, but they’re far from the worst classical strings I’ve ever got to try (as far as brand-name strings go, I’ll go ahead and attribute the (dis)honourable award to Rotosound).
If you’re on a budget, or the convenience of the ball ends is a must, then by all means! go ahead, yet I’d spend a buck more and go the next tier up, namely, in the Ernie Ball field of things…
