      Electro-Harmonix 22 Caliber Power Amp (582993)
Availability:  


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

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.

With our Guaranteed Lowest Price, you can be assured of complete satisfaction and the lowest available price, or your money back!

  • Works exactly as advertised

    As reviewed by Ed on 1/12/2010

    Plug it in and play... you really don't even need a preamp. Makes my Marshall 4x12 thump! The power amp does clip after you turn it up halfway... if you want clean power, keep the volume down.

  • Surprisingly Loud

    As reviewed by Terry on 7/8/2010

    I use the Electro-Harmonix 22 Caliber Power Amp next to my SVT BASS RIG as my "effects" rig powering a 16 ohm 2x10 bass cab. Usually running it full blast or close to it for the overdriven tone of a low watt amp pushed hard. (That's what you hear on almost all guitar recordings, not a high powered stack!) I would not recommend it as a "stand alone" bass amp, but paired with a powerfull bass rig it does just what I wanted it to.

  • Very Nice Little Power Amp

    As reviewed by dgnyberg on 6/16/2011

    I just purchased this amp and I think it definitely does the job. I use my Vox-VBM1 booster portion before this, and the sound is amazing. I'm currently driving a 4x8 cab. The cab was originally a 4-ohm cab, The 22 didn't seem to like it that much. Kept cutting out. Re-wired cab to 8-ohm, and everything is very nice! As has been noted, it does need a power switch. But my surge protector turns everything on at once, so no big deal. Already thinking about building a small head out of this and a tube preamp. That would be a nice Hybrid at no where near the price. And it would all fit on my pedal-board
