Amp in a Can is a portable guitar amplifier housed in recycled cardboard tubing
Sound from the proprietary amplification circuitry is controlled via off-the-shelf volume and tone knobs to the front
There's a 0.25-inch audio jack round the back to plug in your guitar
The Amp in a Can is made from 80-mm diameter reinforced recycled cardboard tubing with plastic end caps and a handy strap
OK, I admit to cheating a little bit with the title. The Amp in a Can is not really a tube (valve) amp at all, but rather a cheap and cheerful portable guitar amp housed in cardboard tubing that weighs less than 200 g (7 oz).
