I have no problem with the sound - tough, but clear. Great intonation. All five strings sound the same - unlike with some 'prestigious' string makers. Sold, last long, can take the abuse. Great for touring and never changing your strings.
My only gripe are the gauges, but they are not unusual - I just don't get the 0.05" they lose on the A & E strings. It results in an uneven playing feel in comparison to the D & G strings. I'm happy with a fatter low-B. If I wanted to use these, I'd have to buy them as single strings, or as two sets, or a set and two added single strings.
If that doesn't bother you and you don't mind harder strings that are a little rough, these are great. If Ernie Ball did a set of 40-60-80-100-125 they'd be my second set of choice. Great quality, just - for my liking - odd gauges as a set.
Sound: Conventional, especially after bashing them in. Similar to GHS Stainless Steels. Solid, but not overbearingly modern. Probably good for rock, which I don't play.
Deffo worth a go if you're currently shopping around for affordable, solid players.
