Hi, I have the same issue with my Jake C (P+MM).
Which Nordstrand pickups did you put to replace the Delanos and how is the new combination with the MM pickup (also replaced now?) ?
I can find a nice sound with the Delanos but I always have to go active with a little bit of bass above the mid position. So it's a crappy sound (not fitting the mix) without some EQ. The opposite of my Fender Am Pro II where it fit just right in the mix.
I was wondering if you felt the same and how Nordstrand fixed that (I was also considering Aguilar 4P-Hot).
