ok boys and girls, I just got home with my squire jag bass and pulled out my fender jag out of the closet, put them side by side, took all the neck measurements with calipers to nearest tenth.
Here they are (Fender vs Squier):
Neck Shape @ nut to 1st fret: C(Fe) / V(Sq)
Width @ nut: 38.2mm for both
Width @ 1st fret: 40.0mm(Fe) / 39.7mm(Sq)
Width @ 12th fret: 56.7mm(Fe) / 56.6mm(Sq)
Width @ 20th fret: 63.3mm(Fe) / 63.4mm(Sq)
Thickness @ 1st fret: 21.5mm(Fe) / 21.0mm(Sq)
Thickness @ 12th fret: 25.0mm(Fe) / 23.5mm(Sq)
Neck Heel: @ ~15fret(Fe) / between 14th & 15th frets(Sq)
Fretboard: Rosewood Natural(Fe) / Rosewood ebony stained(Sq)
Inlays: Aged Pearl Blocks(Fe) / Fresh Pearl Blocks(Sq)
Neck finish: Glossy aged look (Fe) / Natural unfinished(Sq)
Tuners: MIJ style(Fe) / Mexi style(Sq)
I put them side by side, and both line up flush on top of the other, same headstock shape and pattern, same neck lenght, same body contours and length, same neck pocket and screw alignment, pickguard screw patterns are identical at the lower half, the top half has a varied pattern from both models due to different shaping of the pickguard on the fender, the top has a few extra screws around the top active plate controls. Jack and control knob plates are identically cut out and placed, bridges are identically lined up. the bridge pickups are however differently alligned. the Squier bridge J is a tad bit closer to the pickguard. Also the Squier's pickup screws are black, where the fender's are chrome.
Squier's neck plate is the same as Fender's except it has a Squier logo imprinted into the plate.
Comparing them, I'd say Squier is the more versatile bass. neck is thinner and more comfortable and stays more consistent in thickness than Fender's. The thinness also allows for more flexibility over the fender's stiffy neck. So you can actually bend in the neck a bit more for that slight drop tune kinda like a whammy tremolo immitation. Tone is amazing on the Squier, it's just great all around. Don't get me wrong the Fender is a sweet model as well, but it seems to lack some characteristics of tonallity that it was made for, and quite honestly it's a bit too quiet when running as passive as opposed to the Squier's high output pups and they're all passive. Pretty sweet stuff, just need to drop the action a bit and it's gold! Hope this answers some of your questions regarding comparison of the two and their specs....oh and before I forget Squier has the Mexi style bridge as well, Fender has the MIJ bridge.
