Electro Guembass
The tuning is ADGC, there are sheep casings strings from Morocco (possibly nylon strings instead). The body is made of lime-tree, the soundboard is made of spruce, the neck is made of maple, the fingerboard is made of chequer-tree. There are 2 sensors: 1 electrostatic mic and an active Piezo mic (for the volume and tune settings), two straplocks.
