johnny echols

Hi folks... my name is Johnny Echols, I am co-founder and lead guitarist in the rock group LOVE. I just wanted to say hi, and ask a question. I acquired a Gibson SG (Les Paul) Custom, many years ago. The serial number is 614748 (Made in USA) it appears to be made of solid Walnut, or figured Mahogany, if someone could point me in the right direction, It would be greatly appreciated. Thank you.
