What does the bassist in the Lady Antebellum tune "Downtown" use to get that fat slightly distorted sound? You can hear that same bass sound in the Lee Brice tune "Parking Lot Party" I currently play a 1966 Fender Precision with round wounds. I use a Peavey Tour 700 with one 4x10 cabinet. It has a nice fat sound but I'd like to add that subtle bass distortion, kind of a guttural sound, that you hear in both those songs. Any suggestion on how to make that sound possible?
