I currently have a Nate Mendel P that is working great for me - I've replaced the Seymour Duncan QP's for Aguilar 60s pickups, and replaced the badass II with a BBOT vintage style fender bridge.
Strung up with flats it's great for that dead, thumpy sound, but I still miss having the sheen of rounds for pick playing and slapping ..
What does everyone think about having two of the "same" type of bass?
How do you justify it to yourself that you 'need' another?
