Passive circuitry for basses - Part II: wiring diagrams
Here I'll present some different schematics for passive basses.
Feel free to post your own in here. Firts of: an attempt for a passive wiring for a Stu Hamm Urge like pickup configuration.  In this diagramm the P has a series/parallel switch (like the fender S1 switch). The neck J and the P pickups are selected witch an on/on/on switch. The bridge J is dialed in with its own volume potentiometer while the neck J and the P share one which is positioned behind the on/on/on switch. At last we have a master tone pot. Like this it is easy to have a normal J configuration, a normal P config, a normal PJ config and all together. possible variations: one volume pot for each pickup, perhaps concentric with a tone control for each pickup.

Bit confused...
Bought DiMarzio Model J pups, and noticed that they have 4(5?) wires, not like the diagrams which have two... I'm guessing those are incase the bass has an active preamp... ? |

Janelectro -
Funny you should post a passive conversion of a Urge II, as that is what I am in the middle of now. I am looking at a slightly different route and would be interested in your thoughts. Knob #1 - Master volume Knob #2 - Blend based on switch positions Knob #3 - P tone Knob #4 - Jazz tone Switch positions: Position 1 - All three pickups selected - blend pot blends between P pickup and front or rear Jazz pickup Position 2 - Both Jazz pickups only - blend pot blends between front and rear Jazz pickups Position 3 - P pickup only - blend knob has no effect This basically duplicates the active circuit without the 3 band eq hi/low stacked eq control and the seperate mid control. My question is how to wire it. Any suggestions? Thanks! John Last edited by jharms80439; 02-23-2005 at 04:32 PM. |

Would it be possible for you to post a passive circuit for a PJ bass with a Vol/VOl/Tone/Series parrallel switch?
