Here is another guitar that Mitch Easter sold last week.It's a 1968 SG Special and it sold on ebay for $1600. At the bottom is a video I posted before but if you haven't already seen it check it out. Damn...I want my MTV!
I think one reason it did not sell for more is because of non original tuners and this crack(below). Mitch said that crack was there when he bought it(at least 25 years).
