    I have a MIJ P-Bass Lyte Deluxe that has a 3-band active eq. I'm considering removing the pcb, battery, etc. and running it passive (the existing pups aren't active, just the eq). I'd change the pots to vol & tone for each pup with a series/parallel switch to fill the 5th hole. Any problems with doing this mod?

    Look into Bartolini and Aguilar preamps. Many of them come prewired with a switch/toggle/pot for switching from active to passive. Make sure you get one with a seperate passive tone control. This way, you can have your active EQ and then switch to passive and control it both ways.

    Something to think about.

    Does the Lyte Deluxe have a P/J configuration? I used to have the standard P Lyte, and after I changed the pickups I put them in a passive franken bass. They worked fine, so I think you will be ok with doing this.

    I just did this on my son's Les Paul bass. just get the right parts & wiring diagram and you'll be ok. it took us a little over a hour to do and it turned out great. fender has the diagrams on their website and you can get the parts from many places. go for it!

    Showdown - The one I have has a P/Humbucker configuration.

    New pots, caps, and switch are on the way. I'm crossing my fingers that this turns out to be a success.

    It should work fine.

    My P Lyte Deluxe active-to-passive transformation has been completed. Each pup has its own volume and tone (I used 250k pots and .047 caps from Bass Parts Resource) and a DPDT On/On switch provides series/parallel options. In parallel mode, each pups controls work individually, as expected. In series mode, the bridge volume control acts as a master volume, and the tone seems slightly fatter than both pups wide open in parallel mode. Initially, things look like they will work out pretty well. I'm looking forward to getting this baby back in regular service.

    Yep, active to passive is simple. Passive to active can be a pain because of routing though. Glad it worked!
