Josepp, after playing all kinds of guitars with all kinds of strings for over 45 years, I can assure you that I can certainly tell the difference between different strings in both feel, sound, tone and longevity - and I don't care what the brand name is. If you can't tell such differences, then your hearing is defective.

Furthermore, why spend £5 on a set that lasts me a day when I can spend £10 on a set that lasts me a month? Where's the sense in that?

And I don't give a rat's arse what anyone else says, either on Mudcat or anywhere else, about any brand of strings. I buy the strings that I know suit my ear, and I care not a jot whether they suit anyone else. They happen to be Elixir.
