I was in the same boat as you...........I'm only gigging with my 5's, and they were all active instruments (Sadowsky, Modulus, Warmoth Gecko). For my newest bass, I definately wanted to go passive, and at this point I am more than happy with the results.
My
Crook Custom is a 5 string passive, with Bill Lawrence PuPs (reverse P, J), an aluminum Hipshot B Bridge, and the control set up is Vol, Blend, (blank), and Tone. The (blank) is set aside for the Lawrence Q control. I bought it with the PuPs, but we wanted to see how the bass sounded without it first. I'm really pleased at this point, and I may never install the Q.
This bass sits in the mix like no other, with focused tone that is neither too brittle on top, nor too muddy on the bottom. My primary band is heavy on Telecasters, with acoustic guitar, and occasional baritone guitar, mando, and fiddle, and lots of vocal harmony. That leaves only a precious bit of space for the bass to sit in the mix and not get in the way nor get walked on, and this one does the trick!
