Large 19" Tilt Back Legs with mounting hardware. If your ears were attached to your knees, your amp would sound better, but since they usually are located on the sides of your head,
Fender® has Tilt-back Legs! Secured to the sides of your amp cabinet, these legs allow you to tilt you amp back so you can hear what you're doing!
