Wow, an 87 Jem. Sick!!! Wish I had one. The 87 jem had a different neck. it was 19mm at the first fret. The Roadstar, RGs, and EXs were 17 mm thick. They were the same width tho. iirc
I love the '87 Jem. I played the crap out of that thing over the years. It had multiple re-frets and eventually had to replace the fingerboard. I went with an Ebony board for the replacement so the guitar is not completely original anymore. Its a player, not a collector's item.
Here it is, played live, this past February:
The Dimarzio PAF Pro really give it distinctive voice, which cuts through the mix prefectly.
My 2005 Korina has a similar neck with a more rounded profile.
