The Wilson K-4 Bass Pickup has 4 piezo electic elements that install in your bridge. The optional hole position provides natural acoustic bass sound without feeding back. Individual volume control of each string is possible with K4, K5, and K6. The degree of the side-to-side emphasis can be controlled by the exact location of each pickup element. Rotating each pickup element allows individual volume control.
Special mounting tools and mounting bracket are included with each Wilson K Series pickup. You can view the tools and installation shown in Additional Images on page two. Made in Denmark.
