My Fender Thinline appears to be routed from the back, with the back glued on, no top to body joint visible, just the bottom. I love my thinline.....I came close to buying a VM Squier Thinline some years back, but the only color they had was black, and really wanted a shoreline gold, which they told me they could no longer get - am guessing this was when Squier was switching over from regular VM Thinlines to the newer ones with the WRHBs....dunno, but they couldn't get me gold and wouldn't deal on the black one, which I would have willingly bought, little to their knowledge....and now, here I stand, with a Fender Thinline with the WRHBs.....and I rather like them, after messing around with adjustments, sound a lot better then my Epi LP '57 Classics, or whatever Epi calls 'em
