Audiofanzine FR's review

(Originally written by C21h22n2o2/translated from Audiofanzine FR)
- Amplification technology (tube, solid state, ...)?


- Output power?

*...-10 dBu and more... Very high output level!!

- Connections?

...Everything you need! Two programmable FX loops with adjustable level ...XLR ...jacks...

B--amp... crossover... limiter... everything.

- What about controls, effects etc.?

Chorus and compressor... Great...


- What about settings?


- Is it easy to get the right sound?


- Is the user's manual clear and comprehensive?

... Better than perfect...


- Does it fit your music style?

... Yes...

- Which guitar, bass or effects do you use?

Spector... wow...

- What kind of sounds do you get and which settings do you use ("crystal-clear", "fat", ...)?

... every possible sound... I'm a Cannibal Corpse, In Flames, Death fan...

Also great for softer music... from Duran Duran funky sounds to Guns'n Roses rock sounds and more modern stuff like Muse.

I specially like the SWR or Alembic-like settings... but everything is possible from Ampeg to Euphonic Audio and Demeter... Everything!!!

- Which sounds do you prefer / hate?

The main problem is that it's discontinued... good luck! =)

If you are lucky and find it... watch out because it requires 115 volt AC power... It tends to clip easily with an active bass... and also with a high-output level passive bass...

Pros: see description above...


- How long have you been using it?

A long time... I take it everywhere with me... this device is just mind blowing!

- Which feature do you like the most / the least?

You must buy high-quality tubes... and not especially high gain tubes... with non-selected cheap Sovtek or Chinese tubes you'll get a bad signal to noise ratio!

But you won't regret buying quality tubes... Standard selected JJ ECC83 tubes are enough to blow you away!

- Did you try any other models before buying it?

Yes... almost everything available on the market... Ampeg, Aguilar, BBE,Tech21, EBS... But I wanted an exceptional quality and a large sound range to pick from... And I wanted to have the possibility to save my settings!!!!...

- How would you rate its value for money?

...That's a good question... The quality is great!! That's for sure, but the price can be very high, so good luck...

- Based on your experience, would you buy this product again?

I already bought another one!! I found it in an auction. And I'm still looking for more... But I don't wanna become neurotic =)

Back panel:

-Crossover 180 Hz to 1400 Hz

-Direct Out (XLR male swtich Pre / Post and Ground Lift)
Midi Thru, MIDI Out and MIDI In Phantom (to connect the power of a midi foot)
In-Phantom Power
-Switch on / off

In short it is a preamp for 80 years whose connectivity is very comprehensive.


The configuration is simple and rather intuitive.Les various connection capabilities are enormous.
The independently made to parameterize the lamp and transistor provides a real plus.
Outputs Low, High and Full can either have the bass or treble, or both (full). This is useful if you work with several speakers.
Contour settings and equalization complement. It can push its settings without any problems and refine them.
The compressor and chorus are a little small hurt but work. However, I prefer to use other machines specially dedicated.
This preamp is a sort of Swiss Army knife bassist I find everything in there.


The factory settings allow a wide range of sounds. Funk metal through the rock, it is very versatile.

I use it mostly with a low active Ibanez BTB 400 accorée to play in the metal, I'm very happy.

The only problem is the saturation lamps. When did Full selects the preamp breath but it's long since I 'lai not been checked.


I've had two years I used to rock and metal, it is very suitable. It is suitable for other styles too, it was used by Victor Wooten and Les Claypool among others.

I love its flexibility and huge possibilities. Management lamp / transistor is excellent, everything can be set on the preamp.
The value for money is great, with the experience I remake this choice without hesitation.

A preamp very complete!

masplug's review (This content has been automatically translated from French)

the ADA MB1 Tagus has a transistor and a tube.
dentre with a level of output and Tagus.
it is all but jack output XLR DI which is
2 insert his "loop" is super practical and they are adjustable in level DEnter and outputs.
between a jack.
output HI, LOW and FULL one.
an adjustable crossover, a serious limitation.
a MIDI IN, OUT and IN a power supply but with the power supply must be added externally. (or put it directly on the pdalier)
with its very practical dailleurs pdalier.


the handling is not simple at first glance
but it is well trs.
can be found trs sounds good but you have to spend a bit of time because it was soon all EXAGRES trend! (Laigue the grave ... etc ...)


compression is the ... no gloves! but not clean either.
more for a treatment effect of compression.
the chorus is not the glove either. good pedals in loop is more efficient and nicer.
but the grain is, the effective EQ.
sounds good gnrale.
function "contour" and the overdrive is good.
looking for a can, you can get deep bass and brilliant highs while remaining prcis everywhere.
LTAG lamp "talk" too. he brings his key.
there is a "shit" of memory, enough to make it home for diffrent, repeats' scnes small, large, studio, etc ...


I use it for some time but I do not know how many years.
I once had a problem with LTAG lamp CTAIT its power supply.
rpar since it works well trs and I'm happy.
before, I used it directly into a power amp and two SWR 4x10.
CTAIT trs well.
but now I use it with an Ampeg SVT6 head, a Hartke 4x10 and 2x15 6 and Tobias signature.
a sound standard and prcis!
