M: Ein Humbucker
Circuit M1
There are a number of electric basses with just one humbucker, mostly close to the bridge. If this has four output wires - as is usually the case - different coil combinations are possible with a Megaswitch T: here each individually for stronger highs and both in series for stronger bass and midrange.
1. Bridge coil
2. Both in series
3. Neck coil

Circuit M2
Here, in switch position 1, both coils are connected in parallel, switch position 2 is single-coil operation. Both positions sound rather high-pitched. In switch position 3, both coils are connected in series, which results in stronger bass and mids and less highs.
