I just bought a Ibanez GRG170DX and a Marshall 15CD. The stock strings dont feel so good so i thought ill get some new strings. Im looking at Ernie Ball but i dont understand the lingo. I think ill settle with the same gauge as my stock ones. There are drop tune strings and heavy bottom strings and power slinkys. How do these work? Im a newbie so im just looking at strings what feel good to practice. Also if i get a different gauge does it mean that some additional setup has to be done while changing the strings?
