yoTrakkz's review"good but not for me"

JMI Amplification JMI 30/6
The JMI Amp 30/6 is a bit of a departure from the traditional ideas that many guitar players have of Fender amps. This is definitely solid-state, since it's got a few effects, Chorus and Reverb, built in. It has a three-way EQ and a volume, gain, master volume, as well as the aforementioned effects. There's a 1/4" input.


I personally have a difficult time getting good sounds out of solid-state amps with my gear anyway, but that's because I am madly in love with tube amps and I forget what I'm dealing with sometimes. One of the benefits of solid state amps is the effects, and if you'd rather leave an effect dialed in then mess with pedals on the floor, I think that's sometimes the good way to go. The manual will explain the amp well, and give you good safety and reliability pointers, but other than that it's mostly useless as this amp is intuitive enough.


This is a pretty solid-sounding amp. The solid-state world is a tough one to navigate, and thus a really exceptional amp is hard to come by. I don't know if this amp really leaps out above the rest of the pack, but for solid-state at a reasonable price, it's pretty much a good buy. I don't know if I like the clean sound but there's definitely some distortion on it that's really cool. The Chorus effect, which is the main selling point, is certainly better than the older built-in solid state choruses on many of these amps, but I still don't think it's anything better than what you can find on a really good chorus pedal. The reverb is also just ok, nothing to write home about. Reverb is mostly more important for recording anyway, and in which case an outboard reverb of some type or even a plug-in is preferable.


I don't know if I'm in love with this amp, but I'm sure some people will be satisfied. People who just like to play and aren't completely anal about their tone will find much to like. Again, it's reasonable for solid-state, and good enough. I would recommend it to amateurs and hobbyists, not pros or serious musicians.

iamqman's review"Back to life"

JMI Amplification JMI 30/6
JMI amplification has seen a rebirth of the greatest sounding British amplifiers in the world. These amps were the initials on the back and the faceplate of the the original Vox amps from the early 60's. If you come across a Vox Ac30 with the acronym JMI on it then you no you have one the first and very best Vox amps built.

So fast forward to today and you see the company begin to build amps once again outside of the Vox name. These are prefect recreations of the originals and sound and look the part. These amps have such a phenomenal tone that it makes you cry to see the price thye are asking for these amps.


The chassis includes the traditional JMI red control panel, point-to-point wired circuit, three channels and six inputs (Vib/Trem, Normal, Brilliant). The control layout is as follows: Vib/Trem Speed, Vib/Trem Volume, Normal Volume, Brilliant Volume, Cut (tone). Voltage: Variable voltage selector. Available with either Blue Alnico or Celestion Green back Speakers.


As soon as you plug into a JMi amp you will immediately know the difference in the today's version of the Vox Ac30. Compared to the Vox Ac30 they are putting out now is not even fair. This amp absolutely dominates that amp in ever way possible. First of the tone is superb and the build quality is unmatched. Plus these amps are made in the UK, unlike Vox today which is made in China.

Try plugging in a Gibson Les Paul or a Rickenbacker 360 and you'll here a sound that you have been seeking all your guitar career. This tone is flat out addicting. You can sit there and play this amp for hours on end. Hook up one of there treble boosters they off er and let the Queen/Brian May riffs fly.


Other than the price these amps are spectacular. At new these amps come in at around $3699. Youch that is a high price for a combo amp. These are basically boutique quality amps so in comparison to a Bogner or a Diezel then you are in a good place.

I would recommend this amp if you are searching for the best Vox tone period. If you like boutique amps then this amp is right up your alley.

JMI Amplification JMI 30/6
JMI reborn and we offer this fabulous JMI 30 / 6 you'll understand a VOX AC 30 JMI era in all its splendor. So as the legend Canneaux 6 entries with "Normal" "Brilliant" and "vib trem" SETTINGS:
Vib / Trem Speed
Vib / Trem switch
Vib / Trem Volume
Normal Volume
Brilliant Volume
Cut (Tone)
Top Boost (optional)
ECC82 (x 1)
ECC83 (x 4)
EL84 (x 4)
GZ34 (x 1)
(Top Boost features optional extra year ECC83)
The Top Boost is an option and is on the rear panel with Treble and bass control, footswitch for vib trem, available with Celestion Greenback or Fane Alnico Blue 30W ... The amp delivers


It is the most faithful to the original, while HANDWIRED, UK manufactured, the control panel is identical. the firm itself is almost perfect exept two or three details like handles, Black Tolex and corners but does not license JMI VOX and can not use these small units. cons from the bar before the HP was respected and remade as the old combo. The finishes are Black or Fawn Tolex, it seems to me more faithful to the original. Note Custom Colors also more or less tasteful.


The sound of this combo is, I think the most convincing of all JMI vox post that I had the opportunity to hear. uncritically, Vox cc2 is light years away. found in the chemistry of this amp vox, dynamic sound impressive, the power that makes difficiliement apparently saturable, the test of this amp was made in the store and 2 of 10 volumes was hardly bearable. Anyway we realize that direct the sound it delivers is a real AC30 sound. Vib-Trem is the incredible offers a vibrato and tremolo speeds all three packs.


It is difficult to realize the potential of this amp because it will be difficult to express the feelings felt after that test, it is at least for me the best of all. JMI thing is to pay extremely dear, I think the combo is around 3000 Euros in France ... but for an enthusiast looking for a faithful re-release Vox sound must plunge. We're starting to see some qql in stores, they are all to be discovered for re-JMI also publishes other legendary amps and achieved at this level is a real "comeback Brit!

phoenix440's review (This content has been automatically translated from French)" JMI / Vox AC30 / 6"

JMI Amplification JMI 30/6
All-tube amp from 1961 or 1964, I do not know.

VOX everything is marked, and on the back it says JMI.

It is a JMI AC30 / 6 (because 6 entries), Top Boost.

He stalks the girl on the sides to allow them to fix the walls of amplifiers (not present on the reissues).

It is in poor condition (torn tissue, there is a tower that has been done to put a microphone I think Tolex ripped).
The circuit is him in very good condition. Originally, there is just a capacitor which has been changed by a service in its review (he had a concern when I recovered). A system of distortion has also been installed to do cruncher before it thoroughly (and deactivated easily Dessoude).

Welded point by point, I think handmade, all components are "Made in British".

The loudspeakers are VOX (silver alnico I think I'm not sure), in good condition.

I recovered with lamps and Dario MINIWATT Brimar (who lived surment, but not yet found the money to change everything).
There is also a lamp rectifier (GZ34).

Recovered in a barn, I was sold 30 € (yes ...) by someone who did not know what it was. I have no idea of ​​his past, I just know he is still very long without being used in a farm barn.


Simple, 3 channels (or one branch is chosen), 2 inputs per channel (low and high I think).

Attention has put on 225 volts for France

Then we turn it up and play.

Attention, it heats hugely (small vents inssuffisantes).


Very good for blues - rock - hard rock.

You have to push the volume to feel the trick. Very difficult to use, you have to play in a big room where we can not disturb anyone.
This amp is very powerful, it's maddening.

I play an Epiphone Les Paul Slash (micro seymour duncan).

Playing outside in the countryside, with only two lamps amplification (ie 15 watts), a neighbor yelled to 300 meters after 5 minutes.

Obviously the sound is there.


I recently (at least functional), I keep it obviously is a little treasure

I leave my email in case someone wants information: phoenix440 at hotmail dot com
