22 Caliber

Power Amp - DISCONTINUED
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.

EHX FLASHBACK

All things are as they were, except you are there (well…kind of). 1978, Apple Computer was two years old, cell phones… what are they? And EHX introduces a state-of-the-art 200 Watt Slave Amp. If you happened to make it into the Electro-Harmonix Hall of Science at 150 West 48th Street in NYC, you’d see several up on stage.

Over three decades have passed, and EHX is still re-defining amplification, now with the 22 Caliber and 44 Magnum Power Amps that can actually fit in the palm of your hand!
