Perfect match for my guitar
August 27, 2021
These strings are a perfect match for my 50-year-old Alvarez Yairi. They create that satisfying woody sound that I look for.

Very fine strings
May 24, 2021
The Pearse PB acoustic strings are some of the best I've found, after trying out many different brands (I've used the 600L and 570L versions). They have a very nice, musical midrange tone, which I typically don't care for, however with these it is well-balanced in the overall response and does not overpower the frequency spectrum. I've also found that they seem to last better than any other un-coated strings I've tried, especially on guitars that already have a naturally scooped response. Tension of the strings is such that they do not seem to dampen the response of the guitar's top/soundboard, and allows enough physical excursion of the top to reveal the tonal complexity of the instrument.
ProsVery musical sounding midrange that doesn't overpower the response; very good longevity, especially on spruce-over-rosewood. guitars. Very high quality, especially vs cost. Moderate tension for playability without much damping factor.
ConsMidrange may bother some players who prefer brighter strings, but this is very subjective and I found them to be very musical and balanced; they do not seem to last as long for me on guitars that are already naturally warm sounding, such as a typical spruce-over-mahogany instrument, but these are minor quibbles and I'd say they're still worth a try.

A perfect string for my Martin and me!
September 28, 2020
John Pearse Phosphor Bronze lights bring out a rich, balanced tone out of my Martin D-1 which is going on 27 years of gigs- all kind of music. And MANY string changes!

The Pearse strings are definitely a refinement in terms of feel( smoother wrap on wound strings and nice 'give' on fretting/vibrato/bending) over other brands of PB's used for many years.
Great mix of warm and bright tone, and last 3-4 gigs, or weeks of home play- fine with me.
Outstanding strings!

I order these from you for my husband's custom "Blanchard" acoustic guitars. He uses them on his Taylor, too. They are his "go-to" strings for his finger-style guitar playing.

These strings sound vivid and bold. They have at least a long a life as any other phospho bronze strings I've ever tried, but of course not as long as coated strings.
ProsGreat sound

I’ve been buying expensive string, good sound. But these play better.

I have played for 50 years and tried numerous strings and while there are many good strings, these are great!.. They last along time and sound great and have a nice tension to them. I have them on my Gibson J45 and my Maton guitar, and I get compliments on the great sound... yes , these are good guitars but great strings also help!... I highly recommend them .. give them a try!!!
ProsEven sound, long life, nice tension
ConsNone... these are the standard I use!!!

I have used these strings exclusively for nearly 20 years. Nice tone, good feel, and good life. I use these on my Seagull Standard Body to enhance it's "big" sound for larger venues and give me the sound I want for country/bluegrass numbers.

These always outshine the others....

I use the 600's and 550's on my Martin J40 and older Yamaha FG340. You can hear a difference in sonic /tonal quality/sustain almost immediately, and it only gets better as they settle in. I'm part of an acoustic guitar duo ( Hawk Creek ), and the 600's blend better with the sound from my partner's Taylor. The 550's have an insane amount of sustain, but the overtones don't fit as well with the other guitars' sound ( not the fault of the strings..just how the two sound together ), so I only use them for solo work.
I can highly recommend them both.
ProsSustain, overtones, price, longevity
ConsCan't find any.......

600L Phosphor Bronze
September 7, 2014
I use the 600L's on all my acoustics, HD28, Taylor GA8, National N. Martin SP phosphor bronze lights hold their 'new' sound longer, about 6 hours. JP's loose the 'new' sound in 2-3 hours. The Martins work harden after the 'new' sound is gone. The JP's don't work harden for 10 or 12 hours or more. They stay springier and allow two fret bends without hurting your fingers much longer that the Martins. I can use these for practicing for 3 to 6 months. No string goes on stage after 6 hours. I am a uric acid machine and have killed a set of these in one night but that is not the fault of the string. I can do that to any string. These are my go-to string for all my acoustics. Their electric strings work the same way. The work hardening thing has to do with the alloy they use. Keep up the good work.

Best strings ever
June 23, 2014
John Pearse strings last, sound good from the minute you put them on and handle multiple changes in alternative tunings. They don't sound dull like coated strings and they sound a lot more lively than Elixirs. The only strings I'll use on my acoustic guitars. Great for finger-style and heavy rhythm players alike. Anyone who doesn't like these strings doesn't know what good strings are supposed to sound and feel like.

I am writing an overdue review on a set of strings by John Pearse that I bought over 10 yrs ago... and *still* remember the experience. That should tell you something right there. I bought a set. Don't ask me the type or gauge or where I bought them. I can't remember anymore. All I do remember is they lasted no more than a week and they had begun to turn nasty. They corroded or tarnished very quickly. I am not a sweaty player, either. I am not a uric acid "machine". lol.. I am a serious fingerstyle player, however. (and a lady. ) But, I never forgot my experience because it stuck out as "very unusual and bizarre". I have never had a set of strings..in 32 yrs of playing serious, invested fingerstyle guitar playing.. by any manufacturer that corroded as quickly as this brand. Perhaps I got an 'old set' that had been sitting around too long? I hope so. Because that was more than unacceptable. I hope it was a fluke. But, regardless, it influenced my decision to never try them again...just from one bad experience. Sorry. Hope everybody else who's used them is having a very different experience. Peace.

I use these on my Martin OM 28-V, with JP .013 and .017 singles (purchased separately) on the 1st and 2nd to give it better bite in slack tunings, especially open D, which would be weak otherwise. Works great--try it!

I put these on my Yairi DYM94 and after a few days of playing they began to sound like a grand piano. It never rang this clear with any other strings on it.

I think they are the best strings on the market. I use the 700L on my YamahaLL45 and 600L on my Martin D18 and HD35. They get a lot of play on stage and at practices and have proven themselves to maintain crispness and clarity much longer than many other brands. Our lead player uses the 600L exclusively on his National Radiotone Bendaway. Way to go John Pearse.

I've tried many strings and just keep coming back to JP light , new mediums and medium strings. They're perfect for my guitars and never disappoint me. Also, they last longer than most others.

I've always liked John Pearse strings but I've found that they are so hard to find; I would encourage people to try them.

Just wondering what other products does just strings .com sell? Just strings I imagine.

I arrived at using these strings after buying and using a large range of brands and models of strings to find the ones that worked best on my high-end Guild. These John Pearse strings came out as the winners. Nice ringing bright tone when new--then settle into a fine smooth, rich tone for the rest of their playing life. They last well, also. Good flexibility in playing as well. Been very satisfied with them.

Great strings!
February 2, 2011
I've tried quite a few strings and these have been the best. They feel really good and they have a nice warm tone with crisp highs. Could have a bit more bass, but if you bump up to the mediums you have plenty of bass.

Buy 'em!

It is felt that the fundamental pitch is very large?& Deep sound. Moreover, it lasts long.

Very good strings.

I used them for the first time recently on my Tacoma mahogany jumbo. The strings greatly help the midrange and treble on my bass-heavy guitar. I'll keep using them.

Thank you for asking for my input on the John Pearse Strings. I have used them for over 6 years and they seem to work the best on my Taylor 512 and my Takamine LTD-90. They have a very good pitch and last longer than other strings I have used. It would only be by chance that I would use anything else.

John PearseÒ Strings

"English studio musician John Pearse first began researching into music string manufacture in the mid-sixties. The first person, ever, to teach guitar on television - his BBC lessons have been seen in six countries while his PBS series, STRINGALONG, was shown in most US television markets whilst becoming perhaps the best selling video guitar course both nationally and internationally. He is the author of some forty books on such diverse subjects as instrument building and technique- to cooking and the traditional art of fly fishing! In 1965 John began his collaboration with British Music Strings, a London string maker, to develop a guitar string with both a longer life and a more accurate vibrating and nodal pattern. His designs were so successful that, over the years, both British Music Strings and Thomastik marketed strings under his name. John also designed string lines for Bourne Guitars and Jay Associates, makers of the Jester guitar line.

In 1978 he came to the United States to develop a unique line of accessories for the C.F.Martin Company. It was here that he again met dulcimist Mary Faith Rhoads. After eighteen months, he decided to leave Martin, and, with Mary Faith, started Breezy Ridge Instruments to produce the Breezy Ridge Hammer Dulcimer. His revolutionary design proved itself to be the best sounding Hammer Dulcimer ever made. Next came a line of music strings designed especially for the professional musician. Within months, word of these exciting strings had spread across the country and pressure from both the public and beleaguered dealers had persuaded John and Mary Faith to make their line available to stores and things have just kept growing since then!"
