The same system installed in HP Lutherie’s line of Iris violins, now available for your standard acoustic violin. Easy to install, with no modification of your bridge required. Very accurate tone, very powerful, with extremely high signal-to-noise ratio, eliminating virtually all extraneous noises. Violin/viola preamp circuitry is built into the chinrest – simply remove your current chinrest, and replace with the included chinrest. Cello and bass pickup systems contain the preamp circuitry in a small wood component that mounts on the tailpiece. Kit includes a variety of attachment brackets, to fit most bridges, pickup, extra 12V battery, chinrest wrench, cable, and instructions, all packed into a wood box.
