Electro Harmonix Nano 22 Caliber 22w Power Amp

The 22 Caliber is a versatile 22-watt guitar head that fits in the palm of your hand. Just plug it into any 8- or 16-ohm speaker, and you'll get a big, sweet musical sound.

Crank the 22 Caliber's volume, and it'll go into overdrive -- like a vintage amp with a single volume control. Flip on the Bright switch to add some bite and definition.

It's not just a guitar head; it's a shrunken head, with all good voodoo.
