It's what you've been missing in modeling


from Texas

This amp has the entire classic tube amp vibe, from sound to looks, at a very reasonable price. It has a sweet, clear yet full sound on my Strat with Kinman pups, but will start to break up nicely at about 5+. It has a truly great, singing sustain without the fuzz that master volume amps often exhibit. Contrary to what has been said at times, the beauty of this amp is the LACK of extraneous tone circuits and pre-amp gain. I'm sure my Strat's premium pups have something to do with it, but I have been unhappy with my amp tone for awhile...this Ampeg solves that. And if you notice, boutique makers like Kingsley are doing the no-tone circuit/no gain control. This one mirrors that approach to good effect. I imagine some hot HBs would overdrive this to the near-metal stage, but it shines on classic tonal things. It gets real jazz tone at lower volumes, but then moves to the Vox jangle and on to plexi Marshall smoothly. I have been playing since vintage amps where first introed, and I've played them all; I've been using the Vox ToneWorks SE modeler lately so I'm not hidebound about tradition. But from the time I plugged this jewel in, my playing was faster, cleaner and more assured. Tubes give you the edge when they are packaged right. I'll put in some premium JJ 12AX7 and EL84s to freshen it up, but as it comes out of the box, it's a big, big winner. Thanks, Ampeg. You've done really well with this one...

Sings like Canaries in Harmony!


from NZ

This amp rocks! The clean sounds you can pull from it with a strat are unbelievable, and when you push it to beyond 5 on the volume knob, it goes into smooth breakup, overdriving in the way only a tube amp can. Its great for rock, blues, jazz and more. With a strat, definitely try the accordion input, as it brings down the harsh attack. Not an amp for heavy shredders, but great for blues/rock.

the true vintage guitar mate

I tried lots of amps and 2 models managed to match with my vintage 52 tele, Les Paul custom and Sg std. One of them was Ampeg j12t. to my opinion and for being fair the only serious rival for this little monster is a fender blues jr. Ampeg has a smooth clean tone copying exactly the vintage tone of the blues era of the 60's. I also discovered that with a careful miking, j12t plays perfect in big gigs. I used both my amps in a theater (600 people capacity) and no-one believed that this super tome came out these little amps. Ampeg is a "must have" amp especially for blues rocking music

WOW Nitty Gritty tube tone.


from DC

Vintage looks and huge vintage tone. 15w of tube tone that can be used to gig small clubs, but really will shine in the studio. Don't be fooled by those with burned out hearing aids, this little amp was a steal. Reminds me of a ampeg amp I had 25yrs ago, less power but the same great tone. 12" ampeg speaker, solid built like a brick. WOW...

This amp rules.


from UK

This amp bangs. It's a recording amp rather than a gigging job. Saying that, running the line out to a bigger amp sounds amazing. Amp modelers? No way. Use this baby as a pre-amp live! The reverb is a bit bright for my liking, but most guitarists would probably prefer that.

Wonderful, a real beauty!


from Alabama

This is one of the best sounding amps you will ever hear. Its tone and sound are wonderful. I play a Washburn J 10 Orleans through it and the sound is very sweet. Mike
