My first pickup has 2 coils side by side and and fits into a Humbucker cover, the pickups are really 2 Fender pickups side by side. This design give me a lot of scope in shaping the sound by adjusting the height of the coil by moving the flat work. Although it fits in a humbucker cover it is nothing like a Humbucker as they use one magnet in between the both pickup, but my pickup has 6 pole pieces in each bobbin giving 12 magnetic pole pieces and the magnets can be changed I tend to use Alnico 2 & 5 magnets.
My second pickup is baste on a P90 pickup but instead of one coil I use 2 with a separator in the middle of the 2 coils, what makes a P90 a good pickup is it has two magnets either side of the pole screws.
If you are interested in the pickups only they are £50 per pickup.
This was a project for a client, he wanted a pickup fitted to his Resinator guitar The ones you see are piezo pickups discs. These Piezos replicate sound perfectly, the sound of the CBG is the same when it goes through an Amplifier.
Below them are 2 CBG both fitted with a bridge of my own design and holds 2 piezo's.
Piezo pickups have been around for sometime and are also used in upmarket electric guitars, the material used to make piezo's is also used in a cigarette lighter to make the spark that lights the gass.
Both of these Cigar Box Guitars are fitted with guitartec pickups 2 piezo disks glued in for a clear sound
