Help: Does the Silhouette w/piezo have split shaft pots?

Does the Silhouette w/piezo have split shaft pots? I was getting ready to order new knobs, and remembered my Special has set screw chrome dome knobs, and that makes me wonder if they are solid shaft. I won’t be around my guitar all day and it’s killing me to know! Any replaced the knobs on a piezo Silhouette?
