Okay,I've scanned through quite a few threads but can't come up with a definitive answer...I've listened to "East Bay Grease" ,TOP's first album through headphones a few times recently. To me Rocco's tone sounds very full,kinda thuddy,like flatwounds....I've read he only uses rounds....Maybe in the old days he used flats,then switched to rounds? How many companies made roundwound strings circa 1970....Rotosound,Fender,maybe GHS ?....Maybe Rocco used heavy rounds with high action and had a very resonant P-bass,so the tone was more flatwound-like,if that makes any sense....Course,I know Rocco plays very strongly with a heavy hand,which could account for a lot...Another question,I just got got the TOP Live At Iowa State DVD. Rocco played a Mocha colored Fender P-bass with a maple neck...Could this be Paul Jackson's old Fender P,the one pictured on the "Headhunters" CD? I know Rocco has said he has a Fender P-bass that Paul gave him...Sorry, it's a rainy Saturday and I'm bored...
