MM: Zwei Humbucker

Circuit MM1

The simplest circuit enables individual and parallel operation of the two pickups here with two tone controls.

1. Bridge humbucker

2. Bridge humbucker and neck parallel

3. Neck humbucker

Circuit MM3

In the middle position of the switch, the two outer coils of the humbucker are connected in series. Compared to circuit MM2, this leaves more heights.

1. Bridge humbucker

2. outer coils in series

3. Neck humbucker

Circuit MM5

A Megaswitch M enables five different switch positions:

1. Bridge humbucker

2. Bridge outer coil

3. both humbucker in parallel

4. Neck outer coil

5. Neck humbucker

Circuit MM6

This is a variant of the MM5 circuit. In position 3, the outer coils of the two humbucker are connected in parallel, which increases the treble.

1. Bridge humbucker

2. Bridge outer coil

3. Outer coils parallel

4. Neck outer coil
