Here is what The Twelfth Fret has to say about them.Three years ago we were fortunate to discover this small British string making firm. Newtone sent us a few samples and we were in love! We are convinced that they are the finest strings made! Malcolm Newton is the owner and head craftsman at Newtone strings. He is an ex-coal miner, ex-lineman, and spent many years as a wire rope and heavy cable maker. He recently left the industry and found his metier when he began to make strings in the late 80's.
Newtone strings are a truly hand-made string, built one at a time to Malcolm Newton's exacting standards. Newtone strings are consistently true and balanced and use only top quality Phosphor Bronze and pure Nickel windings on tin plated round steel cores. The high quality round core construction results in a full round tone with noticeably lower tension than other strings. Most of our professional session recording customers have switched to Master Class Phosphor Bronze acoustic strings. Mass produced guitar strings use a hexagonal core. This hex core improves the bond between the bronze or nickel winding and the center core of the string so it will ring true. Unfortunately, tiny cavities inside the string between the wrap and the core allow moisture and dirt to accumulate which soon deadens the string. Hex-core strings also have a stiffer feel and slightly higher tension compared to round-core construction. The "Plain" Truth
In my experience as a guitar player and a luthier/co-owner of the Twelfth Fret, I've found that all plain strings are the same no matter what brand I tried. Though some differences show up in the wound strings, the plain E, B and G strings are all the same. But Newtone plain strings are different! The plains are smoother and intonate more accurately. The extra heavy top grade tin plating gives a nicer feel and longer life.
