I did a lot of research on small wattage amps and kept coming across glowing reviews of this Ampeg model, both in vintage and new versions. Bought it here, spent a little money to customize it and wound up with a monster amp.Ampegs have a distinctive tone that fits nicely between the jangle of Fenders and the honk of British amps. This model had a good tone out of the box with the stock speaker, which overdrives nicely but cleans up pretty well when you back off. My Strat with Kinman pickups needs only a one-third crank of the amp's tone knob to get great sparkle.I replaced the stock speaker with a Celestion Vintage Greenback and put in a set of Eurotubes and a Beam Blocker to disperse the highs. The results are amazing. This is an incredibly smooth amp that handles fingerstyle jazz like a 50s club amp, but open it up and it absolutely sings with harmonically-rich overdrive. Don't be scared by the lack of controls: that's its strength. When you hear how pure a tone can be without bell and whistle circuitry to muck it up, you'll be a believer. Buy this amp and be amazed...

! remember when these were new- mid 90's. A store had opened in the New Orleans area, and one of the amps that intrigured me was the Ampeg J12's. There were at least two models- the J12R, which had reverb but no tremolo, and had both a bass and treble control, and the J12T, which had reverb and tremolo, but only a single "Tone" knob. At the time, I liked the R model better- my, how I have changed.

Really, one does not need more than a treble cut, which is what a tone control is, if the amp is built right. Active boost/cut bass, mid, treble and maybe "contour" (whatever that is) have their place- that place being an amp that is designed to do many things. Generally, an amp that does many things, might do them all reasonably well, but it will rarely, if ever, do any of them REALLY well. A simpler amp, designed to do just one, or at most, a very few things, really, REALLY well, can do just fine with a single tone knob- and the J12T fits in that catagory.

Fender-ish chimy, clean tones are not to be found here, at least not in the example I have. But if you want power-tube overdrive at reasonable levels, this amp delivers. Blues and vintage rock guitarist, and harmonica players (I am both) should love this amp. Country-clean players may find it does not get quite clean enough, and metalist will hate it. Do not expect to play acoustic guitar through it.

But, tone and mojo are here, in spades. The blue-diamond patterrn tolex sets it- and you- apart, visually, as does the blue pilot light (I only wish the pilot was on the front, so it could be seen by the audience.) Few amps this size- both dimensionally and watt-output- have a 12-inch speaker (or even room to install one,) but this one does, which helps it bring the tone.


IMO, this is a very unappreciated amp. It does had it's issues, and they are of the sort that could drive you half nuts, but overall, I am quite pleased with the one I have. I put it in the same sleeper catagory as the Peavey Bravo- another amp that too few realize is a good one.
First, let me point out that I am writing this review years after this particular amp has been disncontinued. I got the one I own only a couple of months ago, and consider myself lucky to have one.

This is NOT a "feature rich" amp. It's an amp for someone who will play only blues and classic rock through it. No effects loop, no modeling, not even a bass and treble control. Heck, it does not even have channel switching, and you can't turn the reverb or tremolo off with a foot switch! If you want lots of bells and whistles, you are barking up the wrong tree. Stop reading now and get yourself a Line 6 amp- this is NOT the amp for you.

For those still reading, it's got what it needs- a treble-cut ("Tone") can smooth out nerve-grating highs when you need or want that, reverb is nice, and tremolo-equipped amps should ALWAYS have both Speed and Depth/Level controls- any amp or effects box that does not allow you to control both is not worth your time or money. 15 watts may not sound like much, on paper, but they ARE tube watts, which are louder than SS watts, and it is enough for most occasionals where you would not mic the amp- beyond that, you have the PA and sound man to help you out.
It does have it's issues. Tremolo can get very "bumpy" when turned up past about 6- to the point where you just can't bare it. There is a pretty easy fix for this- installing a cap across two of a tube's terminals can mitigate this- my tech did this, but I need to bring it back for a higher-value cap, as it helped, but the issue is still there. A cabinet buzz is too prevelent to ignore, although mine does not seem to have that particular problem- be sure to test for this if you are auditioning one.

But, once these issues are dealt with, you should have a good amp.
Not enough examples on the used market to establish a value, but I'd say if you can get one for a great price, after any repairs needed, you would be doing fine.

The Little Amp That Could

By GuitarJunky

from Philadelphia

Fantastic little no-frills amp. Ideal for the blues or roots rocker. Very organic sounding tremolo. Tone knob is all you need. Full and deep reverb. Will get you through a small club gig provided your drummer isn't an over the top basher. Really shines as a recording amp.

GREAT amp

By KindaLikesGuitar100020392043

from Orange, VA

This amp is fantastic. I got this amp from my cousin about six monthes ago and it is fantastic. I play in a blues, southern rock, classic rock (etc.) band and use this amp frequently. I also attend local open mic nights weekly. I use this amp on almost every occasion and am completely blown away by its simplicity and downright gorgeous tone. Sounds great cranked for a concert or for playing by myself in my room. Reverb and Tremelo sound great. While the tone is phenomenal the volume is what really sticks out. This is a fifteen watt tube amp and i play in a band with another guitarist, bassist, keyboardist, and a pretty wild drummer. I've played on occasion at the open mics with two other guitarists. I can completely honestly say that I've never turned this amp up past three. It is the loudest damn thing I've ever heard. The only setback is that there is no built in overdrive, but for the kind of quality tone this amp provides, an overdrive pedal is no big deal (i use a Marshall Guv'nor through this amp-- excellent pedal by the way). AAAAAaaanyways... Amazing ampAmazing toneSimple controlsBasic effects (reverb, tremolo)More than band capable volumeWhat more could you ask for?

Great Little Amp

By Prof Dave

from VA

Just got the J12T as a backup to my Twin. So far I have been very pleased with it's thick tone. Played with a G&L legacy, it produces nicely balanced, sustained clean. The tone control --the only equalization! works great. It breaks up nicely when turned up to 5-6, and takes effects well. This is an ideal rehearsal, club-gig amp.

Sweet jazz amp

By Wyckliffe

from Canton, OH

I play jazz standards and mostly use my guild x150 w/chrome strings. I use this amp for practice and couldnt be happier with it. I do think it is a little pricey but I would be tempted to buy another if I lost this one. Warm, very gratifying sound for the more bass oriented tone that jazz players tend toward. I just played it in the store and fell in love.

Club Workhorse

By banjfoxx007

from Brooklyn, NY

I've had one of these since 1997 when it was first re-issued. I've used it ay gigs and at rehearsals. I would run it four to five hours a night and the tone would just get warmer and warmer. Sounds great clean and pushed into overdrive without effects. I have used a zoom 505 and managed to get an incredible array of sounds. Everything from Nirvana, Boston , Brian May and the Police. this amp is very flexible and can do it all. It's simple to use so you can tweak everything up front. If using effects it can be quite loud at 2 and actually drown out a drummer never had a problem with the amp. Always had a great sound. Still have the original tubes. I replaced the original handle with a heavy duty one and I would advise anyone buying this amp to do so if they plan on carrying it around alot.

a nice amp

By ampeglover1

from AR

I have had this amp for about 5-6 years and I love it. Some people may not like the tone or whatever, but you need to get the right amp for the job. I play gospel and blues....lighter stuff. My ampeg works great for that, it has a great clean tone and when you start to hammer down on some lead it gives you an overdriven sound that you can only get from a tube amp. I totally understand why a metal player wouldn't like this amp, but it is the right tool for the job when it comes to blues. The only thing that I don't like about it is that it doesn't have a master volume, but if you put a good overdrive pedal in front of it you can't beat the tone.
