Thanks to Fender boning me again, I just waited two weeks for Bass Strings Online to find out that the gauge of Fender flats I ordered were discontinued so that portion of my order ended up getting cancelled. Oh well, we're all at the mercy of the vender, in this case, Fender. D'Addario doesn't make a 45-105 flat that I've seen so should I go with 45-100 or 50-105? If it were you, which would you choose. Looking for old school thump. Maybe I'm going the complete wrong direction and need to be set straight?
