Do different brand strings, same gauge, actually make a difference with the sound of your guitar? Is it only with more expensive Amps/guitars? I was curious because I remember seeing a thread that said D'Addario (the strings I use) were overrated and that DR strings were better.
Yea, different brand strings have different quality. Obviously there are different string gauges which have different effects, but better string brands will tend to last longer, which is a big plus, and they do tend to sound slightly better as well, but you need a decent amp that'll allow you to hear the smaller changes in your sound better.
Honestly, It's a matter of feel. I can't stand Elixirs of any kind, because they're too slick. I like GHS boomers 11-50.
I used to use elixirs, but their price and the fact that I had to order the stringthickness (13-60) I wanted, made me change to GHS Boomers, and I don't hear a change in my tone. The only thing changed is the feel of the strings, but that's not an overwhelming change. I have a theory that more expensive strings is just a marketing trick to make more money.
