Reviving this old thread to say thanks! My Nashville just didn't sound right, and I was starting to look at suggestions for replacement pickups. After reading all your posts, I decided to tinker with the stock setup. How crazy is this...I lowered the middle pickup flush with the pickguard, and disobeyed my Fender manual to go 9 or 10 64ths on the neck and bridge... and voila! No more muddy tone. I think these tex mex pickups aren't inherently bad; they just require a different setup. I play through a 15" Delta Blues, and it's such a good match for this guitar. Thanks again.
