Here Is what Gordon Giltrap says about Wyres strings:

Wyres have an indefinable “MAGIC” to their sound and it's more than just the fact that they have an astonishingly long lasting string life. Coated strings by their nature last longer than an uncoated string, but with Wyres there is something more going on here, something far deeper! It is the way they “FEEL” when you play them. The warm “SINGING” quality of their plain strings and that lovely clear sustain of the wound strings that I find truly inspirational. These strings are special and I hope they work their indefinable magic for you.       About Wyres   Wyres Strings began from humble beginnings. Our philosophy has always been to test, develop and make the best musical strings possible. Naturally as musicians, we are exceptionally discerning and try to employ our most creative skills to develop great products. Very often musicians will be invited into the factory to test strings and give us real time feedback. In technical areas unfamiliar to us we do consult engineers, chemists and even metallurgists for advice and we try to incorporate new ideas into our production. Our 1st generation of P.T.F.E. (polymer tetra-fluoro-ethylene) coated strings is a prime example of one of these innovations which we debuted at the NAMM 1997 Show in Anaheim, California. We have continued improving on our P.T.F.E. coated string process and are today offering a 3rd generation P.T.F.E. coating.   Wyres Strings are currently manufactured in the USA and we are one of the few companies to actually manufacture their own strings. In the near future, Wyres Strings will also be manufactured in Canada.       This Listing is for 1 x Set Wyres Professional  Handmade Gordon Giltrap  11 - 52 Signature 12 STRING Set of Coated ACOUSTIC Guitar Strings
