The strings are picked up by small cylinder shaped piezo elements with the size of 5 x 15 mm installed directly underneath the strings in holes drilled into the bridge. The volume and sound of each string can be regulated individually by turning the elements.
The Wilson PU is also available as single element PU, which can be installed into the bridge’s leg. Depending on its position, the element capture more of the strings’ or the body’s vibrations.
