Holy crap we are talking some serious tension here. I had to detune twice just to make sure I wasn't up an octave. But I love the tone. And I was surprised to find the slap tone is as good as any, (pop isn't very good though). My G String on this set seems dead? Is it due to the extreme tension? I mean it is really dead. Almost not usable. Does anyone have fender's email? I tried firstname.lastname@example.org. No reply for a week so I am thinking it is not correct. And if it is the right email, I won't be buying any more fender products anytime soon!! I am using them on a bang around bass(SX, that poor neck is going to snap off!!!!) but am thinking of going flat on a bass I use for performing. I really dig the tone. I play mostly classic rock and country. Will flats cut it for rock?? And I am thinking of going Thomastick Infeld because of the tension thing. Comments, Observations??
