The Big Shot is a single-head piezo pickup, especially designed for bigger instruments with low mechanical resonance. The extra strong output signal makes it a versatile choice for a variety of instruments. These include instruments made of relatively thick material, such as the sound board of a piano. It is considerably harder to induce vibration on these thicker materials compared to the thin top of a violin, for example. As the piezo crystals react to corpus vibrations, a low surface vibration results in a low signal and a strong vibration creates a strong signal. The frequency range is nearly linear with a slight peak in the upper midrange. This allows for great upfront sound transmission.
The internal jack can be mounted from the outside so no soldering is necessary. The pickup head is attached with a special double-side adhesive film, which is UV resistant to ensure safe adhesion even after years of use. It is ultra-thin and enables the harmonic frequencies to completely pass through to the pickup disk.
