This was how my aluminium pickup worked in the end after lost of thought, so I hadn't cracked it

but I had  just discovered a new way to make a vibration pickup. Listen to the song "sloth" for how it sounds...

Looks like the aluminium forms 2 coils around 2 mangiest
And then is inductively coupled at the crossover point
Kinda like a transformer
Aluminium although non magnetic does weird stuff with magnets
See aluminium and magnets on YouTube
The secondary coil is like a step up I think
Does anyone know if these alumitones have a power supply?
I think I kinda get the idea but theres something clever
Happening I haven't quite got yet....
Maybe some more experiments are required
In the patent is says u shaped core and a coil off at perpendicular
So presumably the u is like a transformer
And the perpendicular coil is some form of step up device ?
Note the magnetic field adjacent to strings
Maybe you get lenz law and eddy currents
Along the aluminium?
Hmmm intriguing .....

Wicked well done that man!... Thanks Mr Oily,( have emailed you... send us back a mailing address via the email I sent and I will send you one to play with )

and Thanks Uncle John....I have just built a 2 string using these pups, as it should be with a broom handle and it sounds great, works a treat with my cigarbox amp I built !

Bug,

Here's the Alumitone patent:

Going to build a six string version with remote springs like a reberb, to get bounce back on the vibrations

worked on my roasting tin resonator guitar with piezos, so should work on these pups.

Gotcha! Neat.
