bassenvrac's review (This content has been automatically translated from French)" Sadowsky preamp Inboard on Fender Marcus Miller IV"

Sadowsky Onboard Preamp Assembly
Ampeg B1 to live in small clubs
SWR Golight 4x10 Mo'bass + + Big Ben (if I have the courage) live big stage
Trace Elliot 2x10 rpt history not fade of gear
Old Fender Bassman 65 at home because this is my first amp
It's a little anything still everything ...


Configuration: not too simple, you have to be careful
Manual: virtually nonexistent


Marcus Miller sound without the game it's a shame it does not come with the preamp.
Attention to the input setting on the amp


Intended to be installed by me on a Fender Marcus Miller 4c replacing the original preamp and bought at Thomann unassembled kit version.
The equipment is supplied with two mounting planes in English, virtually no explanations, references capacitors shown on the plan do not correspond to those received, which does not facilitate the installation, not easy to do the conversions to mount the right parts in the right place.
For over 50 years planning a good magnifying glass, welds to be made are numerous and hyper careful, do not do the job with the world around ("Honey, you just eat ...").
I installed the hardware on the original plate by choosing MM volume / volume and selection of micro series / parallel controlled by the original mini switch that had become obsolete.
The serial / parallel option microphone is of course not specified in the plan, but doable with a bit of "reflection".
Now if the sound is top, the selection of micro serial / parallel provides more, it would be a shame to miss ...

Internal preamp mounted in the lower
2-band EQ, bass and treble switch and active / passive on the bass knob (push-pull)
1 knob / volume of micro (too bad they are not barbed, it was soon likely disrupt the mic when the handle gets angry slap in;))


The output level of the preamp tt is simply astounding! I mounted my Marcus Miller Jazz Bass sound is dmant. When the strings are new I leave the knob acute tjr 0 and low background, once the strings a little tired I go slightly treble ms dej trs trs are present.


With the bass and treble background 0 is obtained with its monstrous regulation of microphones should all different styles, it's slap personally I prefer the sound of the preamp (high-high). It requilibre bass, the low E to boost the prsence is acute and the ground was incredible shine
With a setting of acute pushed a little you can almost mimics the sound of a metal Ricken 4001 ^ ^


Although a bit expensive but worth it (50 + 310 labor approximately) it completely dope my jazz bass, perfect grace it, change anything and once plugged into my little Mark II and the attention the 104HF DEGT: d

Sadowsky Onboard Preamp Assembly
Identical preamp pedal of the same name as a kit to change the existing preamp with a low active or outright graft it onto a passive bass!

a knob which is also a serious push / pull active / passive

an acute knob

2potards for each volume of the microphones (also confusing when we used a micro balance!)

we regret that the knobs are not serrated, but their strength and courses inspire confidence!


Intuitive course, after the fact c'etre volumes of the two independent microphones!

we get a good sound easily by putting the push in the active position ...

need the manual!


- It is perfect for any style of music, I said ALL well because it is not very typical!
For my part I am energetic music such as rock, stoner rock, and the level of output is simply astounding!

I have mounted on my corvette bubinga 5cordes (the 5th was so so) and it is impressive, the strings are the same value, and momentum is simply awesome! I play with a serious background and an / 8 of acute, so they should now be cut limit for they are not screaming! therefore the new ropes, mini level, and the old strings at a little more important!

Same-settings with another preamp, bold, crystalline, anything is possible now with this amp, do not be afraid to change lest the microphones lose its definition, ca happen again ...
I put 8 because the treble is too present for my taste, but fans will appreciate slap!


The price is more important than the other preamp, but it is justified ...

warwick has changed my aggressiveness of MM (and I joke not, it pierces into the mix dramatically!), the roundness of a jazz bass (well the less obvious, but the round is pretty serious, in the manner of a jazz but not exactly like a jazz, grain and fender warwick differ quite a bit of it!)!

more objectively, this preamp has a rejuvenate my bass and his record is well above aguilar a draft that I find ...

there the accuracy, aggressiveness, but both the roundness and warmth ...

certainly a great product that will boost any low, and when one has a good violin bass, made the move to the next level, and it's really the case, not n'st that a simple expression!

UP AFTER MORE THAN ONE YEAR: The beast is then, and you need to know is tempered in order to make the best with the equalization of the head! But I do not regret the purchase, when I try an active, even a warwick, so MEC preamp, I feel that I play on passive!
