Pickup swap

[ptidwell]

Greetings,

First post here.

I have a Lakland 55-94 with stock Lakland (Hanson) pickups and LH3 preamp.

Swapping out the Lakland/Hanson pickups for Bartolini's jazz pickup 59CBJD-S1 and MusicMan pickup DL5CBC 

Anyone have a diagram for this replacement install for the Lakland 55-94?

 

Thanks.

If you know the phasing of the pickups, you can use this basic bass signal chain:

pickups - blend - vol - tone stack - output

 

You can use a coil tap switch before the blend if there are 4 wires in the MM. If you need a new blend, use a hi-Z Bourns 250k MN or a lo-Z Noll Mixpot (which is slightly complicated to solder).

 

As you can see, the mixing is done before vol, so you need one wire going to the preamp (which is practically the tone stack) from the vol pot.

 

Check that all ground wires are well soldered in their respective places (pot covers, ground contacts...) before the first trial.
