1 tjjohnzz 5 months ago This 1978 Gretsch Roy Clark prototype was discussed in the topic "1978 Gretsch Roy Clark Model 7683" a few months ago. It will be put up for sale in October with Greg's guitars in Daytona Beach. I am giving Gretsch lovers the chance to make an offer before it goes on the market. It is prototype #1 of only 2 made. There are many pictures, videos and discussions on this guitar in the above topic.
