Hey everyone, I have a 4 string Ibanez ATK300 (34 in. scale) I'm interested in having set up for Drop C tuning C,G,C,F. I'm leaning more towards using a 5 string set and throwing out the G string as to keep string tension nice and tight. Would you recommend using a 5 string set for this tuning, or just using a heavier gauge 4 string pack? For either, what gauge would you recommend? I'm trying to do my homework before I decide to have the nut and bridge filed along with the rest of the altering set up. Thank you!
