I need two coils for each string in order to obtain humbucking performance. I simply took the pole pieces from two old scrapped single coil pickups and put them in the lathe. This way they also serve as bobbins for the 0.075mm diameter copper wire.
This is how they look like when one of them is winded with enamelled wire. With this configuration
the nominal resistance for the coils is around 50 ohms or about 100 times lower than on a conventional
single coil pickup. These are gonna need preamps.
All twelve done with my wire winder machine that is controlled by a software called EMC. The pieces
of tape are necessary in order to hold the wires onto bobbins.
The plates that are gonna hold the pole pieces look like this before and after equipped with connector
terminals. I'll go for copper pads from now on considering the huge effort with the approach I've used so far.
Assembly in progress. Tricky to handle the thin wire and also hold it stretched to keep it firm on
bobbins.
All coils mounted and soldered to terminals. Spacer bars of brass visible at the upper left. They are
threaded with M2.
The assembled product. This should also be equipped with another plate at bottom to hold magnets steady.
At the moment they are in position due to the magnetic force only. I also need to get my hands on brass nuts
in the M2 size. A nicety with this pickup is that it has the exact dimensions as a regular single coil and
thus will fit many guitars on the market such as the stratocaster for example.
When it comes to performance I must refer to my hexaphonic pickup experiments
since this one hasn't been tested. Since the
impedance of these are so low they need preamps but all this have been tested earler.
