I had no idea USB Volume Knobs were a thing until today! I’m grabbing one because I keep pushing my PC speaker away from me when I adjust the volume. Even better, this idea was born.
The Spinal Tap wordmark replaces the Marshall logo seen on the amplifier. I honestly believe Thinkgeek or any company could make these without the Spinal Tap or Marshall logo, as long as there is an 11 there for the gag. There’s no pointer on the dial, which spins infinitely, so the numbers are purely for decoration.
