Using an old bin of Lego bricks that hadn't been touched in 15 years, Dave Chatterson constructed this Lego amplifier—a replica of a Fender Princeton Reverb amp—in under a week.
The replica amp is not only fitted with realistic looking knobs, a grille, handle, speaker, switches, power cords and foot switches, but also has similar internal wiring to match. But because all of this was constructed using Lego parts, the amplifier doesn't actually work. That's ok though—since it's not being held together using glue or any other sort of adhesives, if someone were to actually rock out on this amp, it'd fall to pieces. [Fender via CrunchGear]
