Martin MA140 SP 80/20 Bronze Authentic Acoustic Guitar Strings Light 12-54

MA140 - Gauges:12-16-25-32-42-54

These strings are engineered with the performer in mind and they will always stand up to rigorous practice and performance schedules. We start with our highest tensile-strength core wire, then tin-plate it on all six strings for added corrosion resistance; because what you don't see matters! When coupled with our highest quality wrap wire you get consistent true tone that you can count on song after song. Available in 80/20 Bronze and 92/8 Phosphor Bronze. Martin Authentic Acoustic SP® strings offer excellent tuning stability, corrosion resistance and great playability.

Improved Martin SP
I go back and forth between the Retro series and the SP series on several of my Martins and Altmans so I was excited to try the new ones out since I needed new strings. Yes, it is noticeable that there was zero corrosion when I opened the first set. I have less finger noise and the playability is a bit easier. They donā€™t go as far as the flexible core series, but if you use a pick this set sounds more solid and big.

If you always use SPs you will really enjoy the upgrade and if you havenā€™t used Martin strings for awhile give them a shot! I can see moving from Monel on my rosewood guitars to these and Retro series on my mahogany instruments. Ive only had them on for about 10 hours of playing time and they still sound fresh and hold tuning much better out of the box than the previous SPs.

Now I hope they carry the 12.5-55 set which is prefect for two of my Martins.
ProsPlay a bit easier, stays in tune better, look fresh, dependable.
ConsMy only complaints are wanting 3 pack and 10 pack discounts and the new packing, while beautiful, makes it hard to tell if it?s PB or 80/20.
