At the advice of Rickenboogie, I swapped out the stock neck pickup in my 2010 blonde Rick 4003 with a new toaster top pickup that I bought on the Ric website a couple of weeks ago.
Installation was a piece of cake.
I am so glad I made this swap. Having a lower impedance than the stock pickup, the toaster top sounds so much warmer and creamier and oh sooo good! I pull out the tone knob for the "vintage" setting on the bridge pickup, and I play with both pickups on.
One word to describe the tone: saWEEEEET!
Kudos to Rickenboogie for his excellent recommendation.
