Ok so i'm debating a purchase, and im turning to you all for help, i own a gibson sg standard already and im debating buying and sg with p-90's are they that tonally different? Would owning both be over kill? I'm mainly looking,wanting the p-90's for a great clean-single coil type pronounced note definition style clean and slightly overdriven tones is the p-90 equipped axe the answer to my dreams? Are the tones achieved from the p-90 axe that different then the sg standard I already own?
