The Sophie Lloyd signature model takes the form of the bolt-on Aries while adding Lloyd's preferred specs. Three options exclusive to the SL are the Iron Age killswitch, the Sustainiac system, and Sophie's signature truss rod cover. To accommodate the killswitch, the rear Aries bevel is reduced into a sleek, minimalistic contour, while a different control layout is utilized for the Sustainiac system. Various specs are customizable to the customer's taste, such as fingerboard and top wood, finish, and headstock shape.
