I have a little story that involves one of those casings as well.
I already told it a Jules' place, but I figured it goes well with the other stories in this thread.
A while ago a I bought a casing plus mount ring too from Greatdealz on Ebay.
With the BaCHBird project in mind, I thought it might come in handy.
Almost at the same time Krishna (BostonGuitarRepair) told us how the inside of those sixties Thunderbird humbuckers look like. He told us there were MelodyMaker like pickups (with a bar magnet) inside.
So I bought two G3 single coils from the same guy on Ebay. The two G3 pickups will fit in perfectly if I cut off the middle lugs on both.
Haven't done anything final yet, though. I want to wait till the BaCHbird is here.
I did do some hobbying and wired them together as a humbucker.. Simply without any pots, just straight onto the jack plug.
Two single coils taped together with gaffertape.
- two orange wires from the groundplates of the coils to the bridge (ground)
- the white wire from one coil to the orange wire from the other coil.
-black wire to the ground of the jack plug
-red wires to the tip of the jack plug
I mounted this improvised G3 humbucker upside down over the strings with some gaffertape and original screws as "stalks".
I used my (mahogany) BaCH Telebass for this experiment.
The pickup location; just about 1cm from the end of fretboard.
I must admit I'm not 100% convinced yet.
I miss the low frequencies.
Especially if you compare it to the soundsamples Jules put up on his site...
Although that may be caused by the improvised set up? Or maybe a poor connection to the jack (gaffer taped)?
Maybe I should add that I had to take the input volume down quite a bit on my recorder, because the output of this G3 combination is really very high!
