OVERVIEW

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.

FEATURES
  • 22-watt power amp that fits in the palm of your hand
  • Handles 4, 8, and 16 Ohm speaker loads automatically

Great practice amp, very simple, good tone

By StratMan419

Comments about Electro-Harmonix 22 Caliber Power Amp:

The 22 Cal has very good tone in a tiny package. Its features are super-basic and it would've been nice to at least have a power switch. The clean tone is good, not bell-like but clear, and putting a distortion or overdrive through it produces pretty much anything you want. I drive mine through a 2x12 cab w/ a Pro Co Rat and custom overdrive. Both sound wonderful through the amp. I haven't cranked the 22 Cal very much but when I have, it does get a nice, natural overdrive of its own going. The bass is flabby I guess, but I personally like the grungy character the 22 Cal gets the louder and harder you push it. If you play stoner rock you'll probably like this amp. If you want something that sounds pretty and clean like a Fender, then get a Fender.

Great for using your stereo effects pedals and dont want to bring second head

By Windwalker9649

Comments about Electro-Harmonix 22 Caliber Power Amp:

Now, I certainly wouldnt purpously go out and gig using just one of these and a cabinet, but.... If in a pinch, my amp decided just to breakdown to a point where there was NOTHING i could do with it for the rest of the show; this is perfect.
For using it in the way I am, its absolutely perfect, and cheap. I mean, If i was a bedroom warrior, and only had ONE stereo effect (and a second cab of course, but you can get one cheap enough with good enough 12" in it) this is worth the cost. For my playing, I need a good cleanish tube amp, and this would be lacking in that departement, but for what it is; Its perfect.

BTW: BEWARE; DO NOT ACCIDENLY PLUG THIS INTO ONE OF YOUR CHORUS' OR DELAYS, OR SAY BYE BYE TO THAT PEDAL, ITS AN AMP, NOT A BOOST.
I dont know how to rate features. Compared to other fullsize power amps, not much. Compared to other pedal size power amps; uhhh, cant find many.
Ive ALWAYS had a love/hate realtionship with electro harmonix stuff. On there own, I love alot of their pedals. I own a vintage DMM, and couple of 70's Big Muffs. The problem always arose when Id try to put them in my effects chain; they're all noisy, and take alot (too much) effort to get to work the rest of the board, and be somewhat quite. Now, with the pedals from the 70's, I can give them a break. Back then, they werent all built necessarily for guitars, so impedence mismatches on them caused a lot of the noise, but ones made over the last decade.. should have fixed it. I used a Holy Grail forever, and always had to give it a dedicated power supply. Tried a friends soul preacher (i have a compressor fetish, and have all the really great ones, Ross,Keeley, vintage Dyna, a few I built), and it was terrible. As soon as i plugged in more than 1 other pedal, forget it.
This on the other hand, probably due to the fact it isnt a pedal, and is the end of the chain (well second to end if you take the cab into account). It performed much better than i thought.
EH doesnt have a reliability problem Ive ever encountered.
This is were it come into its own. Ive spent alot of time working on guitars, amps and pedals over the last couple years. Much more working on them than playing them. I recently started gigging again after getting a few sessions gigs after not playing out for a while. My pedal board is kind of crazy. I try to cut back on it, and only bring a few, but cant do it. There are some pedals that I may only turn on and use for one section of one song, and wont turn it on again that gig. I have a lot of stereo effects; delays, chorus, rotary emulater, flange, etc. The gigs ive been playing, bringing two amps just isnt rational, so it forced me to play those in MONO. I saw this at a friends, and he had it hooked up to a EH Cathedral Reverb, and a chorus. He was using an Egnater as the main amp, and this exlusively for when he wanted the sweeping stereo sound for those effects, and it was perfect. I picked up a 44 caliber, and keep it around incase I get a gig where I need to bring one of my larger amps (now im using 15-22 watt amps w/out needing more). I'm telling you, if you have extra cabs, and want to use your stereo effects without lugging anther head or combo, you cant go wrong.

.22 Cal Amp

Comments about Electro-Harmonix 22 Caliber Power Amp:

A well made tiny amp. Fun to play. I love light weight class D power. I've owned it about a year and have had no problems. My only remark: I need an amp like this with CLEAN power. For me it distorts too early. Maybe the .44 Magnum is such an amp. I haven't played one.

I must be PSYCHIC...

Comments about Electro-Harmonix 22 Caliber Power Amp:

A Keeper!! (however)..I expected... when cranked.... FLABBY BASS....I got flabby bass. Anyway the distortion is NOT inspiring. Why did they bother?They should just keep it like a real (clean) "power amp" like it says on the pedal. Use your favorite distortion pedal and then you have a tiny (where is it?) amp to impress the drummer and singer at practice. Isn't that why you desire the teeny weenie gizmo anyway? Just don't expect smooth, hot & juicy, tight bass distortion. Like I said, why do they even bother? But as a TINY amp it is very cool. Oh yes, the bright switch is NOT very. AT ALL EVEN. It IS loud enough for practice and maybe some small gigs. I think TWO tiny switches would have been more useful, one for a bright (that really was bright) and a second switch for a basic distortion.

Great Amp!!!

By Super Rick-rn1BO

Comments about Electro-Harmonix 22 Caliber Power Amp:

Amazing amp. Don?t let the size fool you. Or the fact its ss either. Very powerful with lots of headroom. 22 big watts. Probably pushing around 25 at fullbore. When cranked the od is very natural and a very class A style. Gorgeous tone. With the bright switch activated its even better. Grittier. The beauty is when you add your favorite distortion or overdrive pedal. Set the 22 Cal. at 12 noon and you have lots of clean volume. Your pedal will sound like your pedal. Start turning the 22?s volume up a little at a time and you start to blend in the amps od into the mix.I bought my first 22 thinking it would be great as a head for a single 10? cab. It is. But now it sits on top of two 12? cabs. Sort of a mini stack. And wow, what a mini stack. I liked it so much I bought another and now have twin 22 Cal mini stacks. This setup is absolutly awesome for smaller, primitive venues. Of course you could just use one cab and mike it if that is an option. I have yet to try running the 22 into a board.Alot of folks like the 22 for a great backup amp. It is. But I think the 22 is just a great amp period. Great tone, more flexible than what it seems to be and way to easy to lug around. The only gripe I have is that I wish EH had put an on/off switch on it. Right where a normal stompbox switch would have gone. Other than that there is nothing I would change. Excellent job EH! Maybe a future amp could have more eq options and such. Maybe something like a 44 Magnum!

not quite

By dr. D-qU2Np

Comments about Electro-Harmonix 22 Caliber Power Amp:

The cranked distortion of the 22 Caliber in no way compares to a tube amp. The reviewer who described its "flabby bass" had it right. But that's typical of solid state amps and some players may like it. Clean it sounds fine. The main reason I'm taking off stars is that this was apparently assembled by chimpanzees - the jacks don't line up properly so the board is stressed when the bottom is forced in place, the feet are all over the place. Playing blues I generally mic a small tube amp and thought this might work also, but it not quite up to serious playing. That said, it's cute and does have uses: practice, backup amp, target practice, etc.

Comments about Electro-Harmonix 22 Caliber Power Amp:

Worth every penny of the [$] I paid. I carry it in the pocket of my gig bag--ready as an emergency replacement head. I also use it at home for practice so I don't have to transport my VOX Night Train 15W head after each practice or between gigs. That way my VOX stays in our practice space or packed for gigs. I found it a little noisy at 16 ohms, but it is quiet and powerful at 8 ohms. I bought the 22 instead of the 44 because it is going out of stock. I may buy a 44 later as well as a Tech 21 Para pre-amp and use either the 22 or 44 as a second amp at gigs.

Amazing AND Bulletproof!

Comments about Electro-Harmonix 22 Caliber Power Amp:

Once you get past the fact that this is the world's smallest guitar/bass/keyboard amp AND made in the U.S., you notice things like how quiet the preamp is and how really good it sounds! If you have lousy speakers or pickups, you can put an EQ pedal between your instrument and the 22 Caliber, but you might be amazed how good your guitar and speaker sound without a lot of junk modifying your signal. This is very probably the most amp for your money possible and works well at home or at a show. You won't drown out a 100 watt amp cranked to 10, but it will drive a full stack of 4-12 cabinets to a level the sound man and vocalist need. It's easy to overload it on a 4 ohm load, but it comes right back, so just turn it down a bit. Clean sounds are great and distortion sounds better than virtually any tube amp. Buy this and a good speaker and you are set for life!

Comments about Electro-Harmonix 22 Caliber Power Amp:

this is a relly solid unit for what it does. i'm running a Blackstar HT-Dual through this 22 cal into a Blackstar 1X12 and it sounds great, i'm guessing the tone you get has alot to do with the quality of preamp your using.
for a price the features are nothing special but it does what it's supposed to.
i'v not had any quallity issues with my unit
for a price the value is nothing special but it does what it's supposed to.

Great Little Amp!!!

By Snagman73

from Ohio

Comments about Electro-Harmonix 22 Caliber Power Amp:

I only gave it a 4 for features because it does not have an on/off switch. I bought this to use as an practice amp through my valve junior cabinet. I run an RP1000 multi effects pedal though it and it sounds very good and very loud. Amazing for such a little box. It also takes my 90's rat pedal very well too. Great product!!
