I installed the Wilkinson P pup in the neck position and it sounds GREAT!!! But,... when both volumes are at 100% the signal is half of what it is with either volume cut. Individually P works great, J works great, but combined it is only OK. What is wrong? P is a new Wilkinson at 10K, and the J is a stock non-alnico 7K. I ordered a Alnico with a higher resistance of 9K. Suggestions??? It looks and plays awesome. A Lakeland or Sadowsky starts at $1000 up to $8000. Too rich for my blood.
