The jangly single coils on vintage Jags have been replaced with hotter humbuckers, the bridge has been replaced with Fender's "Adjust-O-Matic" version of a Gibson "Tune-O-Matic" bridge (whoo hoo!), and the circuitry has been completely modernized. Here's the circuitry summary from Fender's website:
"Upper: Master Kill Slide Switch, Neck Pickup Humbucking/Single-Coil Blend Control, Bridge Pickup Humbucking/Single-Coil Blend Control;
Lower: Neck Pickup On/Off Slide Switch, Bridge Pickup On/Off Slide Switch, Normal/Low Cut Slide Switch"
So I get a kill switch, coil splitting, and a cut switch! Sweet! This guitar has tons of tonal options. Eventually, I'll probably want to go with some significantly hotter Dimarzios for both the bridge and the neck, but I'm not complaining. I think Fender did a great job of modernizing a classic guitar, kinda like Dodge re-releasing a 1970 Challenger but with air bags, anti-lock brakes, a modern AC system and BOSE stereo, and a more fuel efficient HEMI V-8.
