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.
