The patented Oyster pickups offer a natural and powerful reproduction of the instrument sound without active circuits or preamps. The excellent sound result is achieved by a perfect interaction of diaphragm, piezo element and plastic contact gel. All Oyster models are fixed with a dual-sided adhesive foil or alternatively with a removable glueing pad that won’t damage the instrument. It is designed for installation inside a guitar using a thin, surface-friendly adhesive foil. Extremely broad frequency range as with all Oyster models, which obviates the need for further equalisation.
