The GSP38WB features an attractive wooden base and the innovative Hercules Auto Grab System (AGS) yoke: the arms turn in and up with the weight of your guitar to hold it securely and simply open up when you lift it off. Also features a specially designed AutoSwivel yoke, which rotates clockwise and counterclockwise to allow unconventionally shaped guitars and basses to hang vertically. The yoke is completely covered with finish-safe Specially Formulated Foam (SFF) rubber to protect your guitar's finish.
