EJ 15 - Gauges - 10-14-23-30-39-47EL(Extra light) - Gauges - 10- 14-20-28-40-50Over the the last 8 years of my playing experience, tried out different manufacturers and the whole restringing process has been somewhat divine. The most important lesson that I have learnt is - If you donno how to re-string an acoustic guitar properly it doesn't matter what brand it is. So get that right !Now to the review:Tried every brand that i have got my hands on - John Pearse's , martins, fenders, ghs, dr, rotosound, cleartones, Dean's, pretty much everything except for the elixirs( so no comments on that) and have always come back to these two brands that fight for the top position in my list - D'addario and Ernie Balls... Both to me are excellent strings. Daddario- EJ 15 Feel - 5/5 (better than EL, but has a little more buzz than the EL)Tuning - 5/5 ( Always stays in tune)Lifespan- 4/5 ( Coastal area- 2 weeks without any string lube, Dunlop string conditioner on, goes for another 2-3 weeks, playing time - 2-3 hrs a day)Tone- BrightErnie Ball ( Extra Light)Feel - 4/5 ( is a little hard, but hardly any buzz )Tuning - 5/5 ( always stays in tune)Lifespan - 5/5 ( they beat the d'addarios hallow. easy 3 weeks before i use the conditioner then another 3-4 weeks and still have a lotta punch left )Tone- Not as bright as d'addario but has its own flavourBoth are amazing brands making seriously good strings. and they end up being personal choices. Cant go wrong with either of these two brands
