i recently got into death metal and have a few questions. The guitar I currently have most likely cannot have 11.s so i will have to get the nut filed. Will I be able to go back to 9.s or 10.s if I dont like the 11.s? Also will 11.s work for drop A and B? Can I standard tune with them? Someone also recomended me getting a baritone for really low tunings? Will i not be able to get low tunings out of an Ibanez rg 321?
