Guess that all depends on what you're looking for. The sad truth is that both sounds fell out of favor with the bass buying public years ago.
the factory pup epiphone used in the korean rivolis was pretty horrible. I can't image they were ever in favor with the bass buying public!
the model g is a better sounding pup in comparison but is also nothing like a gibson mudbucker, but I'm certain you know that. I have a mudbucker for it but until the neck issues with my rivoli are resolved, there is no need to install it.
