Re: Fender Jangle, Twang, and scale length
I've come to the conclusion that the two most critical factors that give fenders their twang and jangle is the design of their bridges, and their pickups.
You can take an alder body and bolt on a maple+rosewood neck or an all maple neck, put a floyd rose and some humbuckers in it, and it'll sound rich and beefy (and coincedentally, it'll essentially be a charvel or jackson).
But put those bent steel saddles on it in a fender-type bridge, or a tele bridge, and some single coils, and it changes completely.
Bolt-on construction gives a bit more snap and articulation (IMO) than set neck, but that's not enough to change the sound of the alder/maple/rosewood combo to a twangy thing.
Wilkinson bridges are warm and beefy sounding. They don't sound anything like a vintage fender bridge (that said I haven't played the VSVG, which is supposed to sound more like a vintage fender bridge with bent steel saddles). Floyds don't sound the same. Even if you leave the vintage fender bridge on and change the saddles out to something like a Graphtech set (which I've done), it warms up the tone considerably and loses a ton of the jangle. Still, the essential bridge design does tend to leave a bit of it in there.
And the pickups, obviously, have their own sound.
Despite the bridge and pickups having the most impact, i still think it's the sum of the parts more than just those two factors that makes the fender so jangly/twangy
