Pickup:: PJ Wiring
Now here is a wiring method for the Precision Bass (P-Bass) pickup
and Jazz (J-Bass) pickup. This method has
the sensors in parallel wiring mode.
This wiring method shown is for passive sensors.
NOTE: You should be able do this with active sensors, but you need to get power
(9v or 18v)
to the sensors.
This configuration is common on many Precision copycat models, such as
Ibanez, Jackson, Carvin, and many others. The beauty of this configuration
is that you get the best of both worlds, a nice Precision pickup sound, and a
similar Jazz bass sound, which works well for live situations, plus the single
bridge jazz bass pickup sound.
The critical thing here with this type of pickup configuration, is that when
you use a single coil Jazz Bass pickup, you will need to sacrifice the
hum-canceling wiring of the Precision pickup, thus you will need to wire it as a
single coil pick. If you do not do this, you will find that two string are
definitely out-of-phase. However, if you do not wish to have two single
coil pickups, which are susceptible to hum, you should use a split coil J-Bass
pickup (Dimarzio make this type) and then you can wire the P-Bass as
hum-canceling and have the best of both worlds, with out the hum.
Note: that the sensors are wired this time in parallel, not series. I
also have two volume control knobs and one tone control. There are other
options for this too.
Below is the inside wiring of my P-J fretless bass. Note the back CRT
paint on the walls and back. This is conductive paint for electronic
shielding, and it works very well.
