I'm looking to buy a 1988 model Sillouhette, but the seller doesn't have much information on the guitar. He bought it used in 1990, and says it was stock when he bought it. It has sat in its case since then and he's only played it once or twice. What would be different about this guitar spec-wise from the current production models? It has a Music Man hardtail bridge, string through body, HSH pickup config (bridge and neck have covers on them). Any info would be very helpful. Thanks.
