Hi all, I have been playing guitar for 40 years and have never owned an Epiphone. I was able to pick this one up from a friend. As near as I can tell it is from 1991, made in Japan. Does anybody have any stories or knowledge of this model? The previous owner added the Bigsby and replaced the stock pups with Seymour Duncan Antiquities. Loving it so far but I am thinking about changing the spring in the Bigsby to a taller one. Thoughts and comments welcome.
