The K&K Sound Big Shot Internal is a single-sensor 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 stronger signal. The frequency range is nearly linear with a slight peak in the upper midrange. This allows for great upfront sound transmission. This model includes a gold strap button instead of the standard chrome strap button.
The K&K Big Shot Internal includes a prewired internal-mount endpin jack. The jack is prewired so no soldering is necessary. The pickup sensor is attached to your instrument with a special double-side adhesive film (included), which is UV resistant to ensure safe adhesion even after years of use. The adhesive is ultra-thin and enables the harmonic frequencies to completely pass through to the pickup sensor.
