Hi Guys, I have an SG I believe is a '69 special based on serial number. Can anyone confirm? I also wonder why it has silver pickups instead of black. Were they replaced? Lastly, do you have any thoughts on value? I have seen similar ones on Reverb but they are typically in a little better shape and have more original components. Mine has a replacement bridge and tuners. I have the original knobs, although one has a piece cracked off. I am not sure how all that affects value. Any thoughts appreciated!
