I have this ESP M-1 CUSTOM, which I bought in 1988, and about which I know nothing. Being a Strat guy, I never played it; I just bought it cause the shop gave me what I thought was great price if I bought it along with an amp I was after - I got the guitar, the case, and a new Marshall 4001 (Studio 15) for three bills. Over the years I've tried researching it, but always came up short - even what's left of ESP couldn't tell me anything. Can anyone tell from the images of its Japanese; American; worth much; why it has a Jackson-looking headstock, etc? Any info would help.
