DiMarzio Model P® Bass Pickup
Important: Read all of the following instructions before proceeding. If any questions or
problems arise, you may refer them directly to us.
The Model P® is a direct replacement pickup, for installation in all Precision
basses except those instruments of very early release which do not have two-
section pickups. No modification to the standard Precision bass is necessary. If
you choose, an optional miniature switch can be installed to provide Dual-Sound
capability. Instructions for wiring this switch are included in Part II of this sheet.
Part 1
A) The first step is to remove the original pickup. This can be
accomplished by the following: unscrew all screws fastening the
pickguard to the bass, and lift the pickguard carefully from the
instrument. You will have to loosen the strings to accomplish this.
Now remove the four screws holding the original pickup in place. You
can now disconnect the pickup by unsoldering the two wires that
connect it to the bass. Unsolder the two wires furthest from the
pickup; one wire should be disconnected where it is soldered to the
volume pot, and the other where it connects to the base plate
underneath the pickup. The pickup can now be removed from the
bass. Both halves of the original pickup can be left connected
together. Now install the Model P® pickup: draw all four wires from
the Model P® through to the control department, and then screw the
two halves of the pickup into the bass. It does not matter which side
the two halves sit in.
B) Solder the red wire to the same leg of the volume pot the original
pickup was connected to. Solder the green wire to ground, preferably
the back of the pot. Solder the white and black wire together. You
should then put a piece of tape on this solder connection, to make
sure it does not make contact with any other part of the circuit. You
can now replace the pickguard, retune the strings and adjust the
heights of the Model P® sections to suit taste. Fine adjustments can
be made with the pole pieces.
