Not so, I had both side by side, there is absolutely no comparison between the Epiphone EB-0 and the Gibson SG except they look a lot alike, The EB-0 has a bolt on neck and one cheap pickup, the Gibson SG is a glued neck and has two great pickups, the sound difference is like night and day, also, I would buy medium scale strings for this bass because the short scales are just a tad too short, with the short scale LaBella Deep talking bass strings the silk may rest on the nut, the medium scale gives you 2 more inches. I used to use round wound strings but I agree that the bass sounded muddy, I put flat wound Labella deep talking bass strings on it and viola, no mud, very nice tone
I use and love LaBella flats as well as short scale basses. So the Gibson SG sounds like it's right up my alley when I get ready to add new bass to the group.
