Marshall MS-2 Mini amp

Marshall MS-2 mini amplifier

This is a small amp (about 5 inches tall by 3 inches wide). It has a belt clip on the back, input and output (for headphones) and is powered by one 9v battery (the square ones).

It's like the one Jack Black has when he's wandering around the classroom playing guitar in the movie 'School of Rock'.

Unfortunately it does not go up to 11. :)
