JP: Ein Singlecoil und ein geteilter Humbucker

 

Circuit JP1

In this widespread combination of pickups, two volume and one tone controls are often used. Only a single volume regulator is smarter for practical stage operation. A hole will be free during the renovation; So two tone controls can be connected, one for each pickup. A Megaswitch T enables individual and parallel switching.

Circuit JP3

With this circuit, both pickups are connected in series when the switch (Megaswitch T) is in the middle position. This results in stronger bass and mids as well as fewer highs. Only one tone control makes sense here.

Circuit JP4

This circuit offers extended options through the use of a Megaswitch M. The two coils of the split humbucker can be connected either in series or in parallel. With series connection you get stronger bass and mids, with parallel connection you get stronger highs. A version with two tone controls is shown here; in instruments that only have space for one, this is connected in parallel to the volume regulator, e.g. in circuit JP2.
