hi- sorry - my response before sounded a little forward. That seam your pointing to, is the 2 pieces of the laminate top comming together down the middle, theye are glued on to a couple of pieces of soild maple underneath. I do have 2 J.P. edwards les pauls , again they both have a one piece mah. back with a 2 pc maple top , and a 2 pc -thin flame laminate gluded on top of the maple top. ( i will post some photos tonight) . i have heard that some have complete soild tops ? but, i really do think yours is the laminate top. in any case, these are excellent guitars for the money! I got one from 1995 , one of the 1st one's made, and got the 2nd one off ebay a couple of weeks ago, except for the s/n , i can not tell them appart.
