Review: Change is as good as a rest - I've bought Elixir strings for as long as I can remember and can't fault them...so why did I buy Martin strings? Well, I'd bought a Martin guitar and so thought I'd match it up with these strings as they were highly recommended. I'm not a big fan of new strings...much prefer them when they've been on a few weeks and lost that bright zingy sound. These didn't really suffer too much from that and whilst they sounded new and bright they had a rich depth from the off. I've had them on now for around 3 months and they still sound excellent and stay in tune despite some bending and changing tunings several times. They are certainly as good as Elixr strings whether they ;last as long remains to be seen but so far so good...I should add, I keep strings on for a long time as I like the dull sound as they age! I would recommend trying them as theya re a good price and I'm sure you don't need a MArtin to appreciate their sound.
Review: Wonderful tone. - You don't buy these strings for long lasting brightness and durability - go to Elixir if you want invincible strings. You buy these for the tone. And these are the best sounding strings I've played. At first they're nice and bright and rich, then they age like fine wine! The more you play them, the better they sound. They get to a nice woody, vintage tone after about a month of playing. Definitely the best strings I've used, and after trying Gibson's, D'Addarios, Elixirs, I think I'll only ever use these from here on out. The only drawback was a string snapping when tuning down after about a month and a half of playing them, but I can easily look past it for the tone these bring.

## Questions & Answers

**Q: Are these ok for use on a resonator?**
A: No. 12s are much too light in my view, especially when your reso is tuned to open D or Open G. Heavy strings (15-56) tuned D or G will make it sing and are designed to come up to pitch lower tensioned. I've tried Martin's reso strings but NewTone Strings, Michael Messer National Phos Bronze are tops. :-)

**Q: Would these be suitable for an old resonator guitar?**
A: After looking at the Martin string catalogue I would say that Retro strings are NOT suitable for a Resonator guitar.
Their catalogue does, however, show that for a Resonator guitar their "CLASSICAL STRING - Nickel wound" is suitable and their reference for those is Model number M980 (16 - 56 gauge) with a tension of 172.8.  The RETRO strings, which I have myself, are for normal wooden acoustic guitars.

### ⭐⭐⭐⭐⭐ Simply the best strings
*by M***I on 21 September 2020*

I've tried a lot of different strings on my hummingbird. Didarios (all types) are always clattery and metallic. John Pearce nickels are too wooly. These are just right; a nice bit of twang and sparkly, with plenty of bass and depth. I've put them of 3 different guitars (Gibson, Taylor, Cort) and they are just by far the be best sounding strings on all of them. I almost feel obliged to buy a Martin guitar, given how good their strings are ;)
