As an interesting aside, I recently purchased a 2008 Amer. Std. Tele. and was wondering what strings the factory puts on. The website says Super 250s:

for all US and MIM non-tremolo electrics.
An email to fender with this question received this reply:

Gauges: (.009, .011, .016, .024, .032, .042),
p/n 073-0250-203"
ships on 2008 Amer. Std. Tele.
