22 Caliber Power Amp

The Electro-Harmonix 22 Caliber Power Amp is a versatile 22W guitar head that fits in the palm of your hand. Its excellent tone and extreme portability guarantees it a spot among your mainstays for performance, rehearsals, or recording. The 22 Caliber delivers everything that you would expect in a much larger amplifier. Though the input and gain structure was optimized for guitar it will work great with other instruments as well. Just plug it into any 4-, 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.

The volume knob controls the volume or loudness of the amplifier. As you turn the
Volume knob clockwise, the 22 Caliber's output gets louder. At a certain point in
the knob's travel, the output will start to overdrive. At this point, you are beginning to exceed 22 Watts on your loudest notes. Turning the volume knob further clockwise will produce a more overdriven sound from pure power amp saturation. When engaged, the power amp's bright switch adds a subtle high-end boost presence to your output signal. When in the normal position it is defeated yielding a signal that passes from input to output uncolored.

Plug the output of your guitar, effects pedals, or any other instrument into the input jack using a standard 1/4" instrument cable. Connect the 22 Caliber's output jack directly into almost any speaker cabinet. Use a speaker cable between the Electro-Harmonix 22 Caliber and speaker cabinet as you would with any power amplifier, though you can get away with using an instrument cable if absolutely necessary. Additionally the speaker cabinet must have a power rating equal to or greater than the 22 Caliber's output power capability. A speaker cabinet with a 30W rating is recommended. Electro-Harmonix has always been a supporter of the portable musician, particularly when it comes to amplification. The 22 Caliber power amp surely proves that great things come in small packages.
