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.

Excellent for the price

These are really a quality guitar string for an affordable price. After changing them over two weeks ago they still are sounding good. I think that I will be using these going forward!

JP New Medium Phospor Bronze

I had been using coated strings for years, but thought I'd try the JP's based on John's recommendation. I am glad I did! They sound great from day one, and maintain their tone for weeks. At about half the price of coated strings I was using, I could change them twice as often - but I don't have to!

John Pearse New Medium Strings

After trying a lot of different brands of strings and gauges this is still my favorite set of strings for both of my guitars. Shoreline has the best price and with the AGF discount and their great service you just can't do better any where else!!.
