I actually think that metallic T burst looks hideous, but that's why there's variety. :icon_thumright:
String trees are more a question of "should have" than need. They correct an inherent flaw of the cheap-to-make-and-also-strong strat and tele headstocks, which is the lack of angle on the backside of the nut. EVERY stringed instrument has an angled headstock ensuring a good downforce at the nut, EXCEPT fender products. Sure, you may not "need" a string tree, but you may be losing volume, tone, and sustain because the string vibration is not stopped completely enough at the point of the nut. You want the string to be very firmly pressed down at the nut, so minimal vibrations continue up to the tuners. It's the same reason the Jazzmaster bridge is so heavily criticized and said to cause poor sustain. The fix in that case is to put a pressure bar that does the same thing as a string tree - make sure the strings approach the bridge at a decent angle from behind it.
