John Pearse Phosphor Bronze Acoustic Guitar Strings

John Pearse Phosphor Bronze is our best-selling string. The tone is meaty, articulate, and lively, and in my experience (your mileage may vary, of course), they last longer than any other uncoated strings I've ever used. This is why I use these PBs on my own guitars more than any other string. 

My favorite gauge, by the way, is the New Medium. Stringmakers have been producing Custom Light and Slightly Light strings for years, since folks often like a string a bit lighter than true Lights, but not quite as loose and slinky as Extra Lights. Well, John Pearse's New Medium gauge fills that same gap on the heavier side of things. New Mediums are just a bit heavier than Lights, but not quite as heavy as true Mediums. It's worth tossing in a set with your next JP order—if you're like me, you may find yourself restringing all your guitars with New Mediums.

PB Bluegrass - Excellent Sound

Finally found the string that brings back the bluegrass sound to my Washburn. Good base and twang at the top. Hey, sounds good playing normal stuff too.

John Pearse strings brings the zing

Have used these for 6-7 years now on my Martin. Have a rich, warm tone with shimmering brights. Sounds fat enough when strumming, and like a 21 year old stripper breathing in your ear when finger picked. They last a bit longer than the competitors, with the exception of coated strings. Use Fast Fret after every set and you'll be fine and on time. Thanks Shoreline for the best price and free shipping.

John Pearse PB New Mediums: Great strings! Shoreline great to deal with, as usual!!

I wanted to give the John Pearse strings a try after several people on Acoustic Guitar Forum raved about them. Of course I went to Shoreline (where else would I go?) as they are the very best to deal with. Once there I read John's comments about his love of the New Medium size so decided to give them a try. I ordered two sets of PB's in New Medium. As always, shipping was free and fast and they arrived in short order from the opposite coast. I put a set on my Emerald X20 custom carbon fiber guitar and I have to say, these are great strings. I bought the 'regular' ones which are relatively inexpensive and that have lasted a good amount of time so far. I normally run coated strings (Elixir Nano's or D'Addario EXP's) but so far these strings are holding up great. The one is warm and wonderful, the feel is really good, not too slippery like the Nano's but not quite as grabby as the EXP's and the New Medium size is perfect as well. I'm going to order another couple of sets in 80/20 as well. Highly recommended.

John Pearse Phosphor Bronze Lights

Have used these for a few years on maybe 7 or 8 different acoustic guitars. I find they keep their tone and suppleness very well, even compared with coated strings. I really like the warm tone which develops after a couple of hours of playing and lasts a good 4 to 6 weeks for me. They are excellent value and of course Shoreline service is excellent too.

Better than D'Addarios?

Hard to discern a difference between these and D'Addario PB lights that I've used for years.
