Welcome to the Forum, Teobeck! It's a pleasure to have someone here with your years of knowledge and experience. We have a few members here that are well-steeped in the Blues, so you could fit in quite well if you choose to stay.
It sounds like you have some fine equipment as well, and appreciate great, pure tone. I have tricked out a few of those Epi Sheratons with nice pickups and all the good electronics, and they have each turned out to be excellent guitars.
Keep on keepin' on!
If you find somebody to love in this world
You better hang on tooth and nail
