Wow - you guys are good. Nice detective work!
When I first saw it I thought the same thing as Jos regarding the size of the imprint/stain… btw, there's actually paper there… then like Darwin mentioned there's black paint in the corners as well as the tilt adjust mechanism. And being its a maple body, it could have been indeed a Broadcaster…. a day or so later I notice some markings on the paper residue that seems vaguely familiar so I GOOGLE' G&L Broadcaster to see what the inspection sticker looks like and there's the same marking - remnants of the rectangular frame… SO then I checked the pot dates… saw that there is in fact a body stamp - but as Ken points out, its barely visible and really hard to make out… BUt, it clearly shows a 9 after the 8 in the year… And I wondered why it would be stamped at a later date again like Ken mentions but one more check to the BC neck pocket image and just like Jos stated - nope, Broadcasters didn't have em!
So, it does seem its was a repurposed Broadcaster body… but still kinda strange to think they'd ship one out like that… I thought perhaps it was a factory 2nd or and employee guitar… A few more things - it has the early selector switch mounting screws but is missing both the copper ground plate in the control cavity and the tilt adjust set screw…. this along with the funky shielded braided wire going to the output jack makes me think it was an employee guitar or was an left over body that some folks cannibalised at some point - and took the neck, and parts from an '89 ASAT and assembled it…. But the stamped date of 1989 on the neck pocket would rule this out…
Anyway, below are more photos - Btw, I swapped out the crap EMG select pu's and installed a set of '87 MFD's that sound Fab! The p/g is the customised powdered alum one that I used to have on my burnt '90 ASAT SIg. One last thing, the rosewood or ??? of the fingerboard is very light in colour and seems to dry out very frequently… It was that way when I bought it so I used quite a bit o lemon oil but it didn't take long to dry out… I recently rubbed the fingerboard down with Fast Fret which I believe is just mineral oil and it revived it but already has partial dried out. Doesn't bother me or affect the playability but its a bit curious...
Anyway - thanks guys for chiming in!
Cheers,
