It's a bolt on, checks out in every regard - super light, easy to play, sounds great... but there's some problems. First, I discovered that someone pulled the original pickups and replaced them with FVH100I Gotohs, so there's no chance of getting a date code off the original Greco pickups. Second, it's got this weird variation on the "Gneco" inlaid headstock logo. I've got 2 LP Grecos with original pickups that I've dated to 1974 and 1973 respectively, and I found a graphic of some of the variations of the Gneco logo, but I can't find any other examples of this logo anywhere online! Greco guitars pre 75 have the 3rd logo and post 75 have the 4th, but can anyone help me ID this lovely old SG with the 2nd Logo here?
