Circuit MJ1

There are electric basses with a mix of a humbucker and a single coil, with the humbucker usually sitting in the bridge position. The simplest circuit for this offers the following options

1. Bridge humbucker,

2. Bridge humbucker and neck parallel

3. Neck

Circuit MJ4

This circuit enables the pickups to be connected in series in positions 3 and 4, which increases the bass and mids and reduces the highs.

1. Bridge humbucker

2. Bridge single coil outer coil

3. Bridge humbucker and neck in series

4. Bridge single coil outer coil and neck in series

5. Neck
