Why is the electrical cavity of all DAlegria basses shielded?
The objective of shielding the electrical cavity with copper is to build a “Faraday cage”, where the magnetic field is null internally. This means that with this arrangement it is possible for the electric circuit not to suffer influences from external magnetic fields, which would represent noises and interfere on the instrument’s sound. The use of copper, due to its high conductance, allows a high level of shielding.
