The popular Realist transducer which mounts under the foot of your bridge. Held in place by string pressure, this pickup is simple to mount, reliable, and certainly popular. Requires a degree of vigilance to keeping your bridge in place (which you pretty much need to have anyway). Includes clips for mounting the jack to your tailpiece, which is achieved by removing one or two of your strings and threading them through the clip and back through the tailpiece. The string pressure holds the clip, and jack, against the back side of the tailpiece. An efficient and sturdy mounting system!
