If you want to buy the Sans Amp, try this and save money!!!

By fredolee16, 02/02/2015
First of all keep in mind that this behringer unit of the SansAmp unit is not a overdrive pedal concept. It is a tube emulator so those guys that are trying to bash the pedal because "the drive knob doesn't work well", didn't read or understand the concept of a bass driver pedal (tech 21 or Behringer BDI21). I play bass three times per week. Play in a local church but play for a rock band too. I play bass since 2000 and have several basses and other stuff. From 2003, the Tech 21 SansAmp bass driver was my main trick to my sound. For whatever reason, I decided to sold it to try something different but every stuff I tried doesn't give me that warm like Geddy Lee sound that I loved. I see this Behringer in a local store and immediately noted that is a copy of my loved Sans Amp bass driver so, for $30 I decide to take the risk. What a surprise. It is almost identically. I my opinion sounds a little bit better because has a little more midrange so I find it that it add less color to my sound than the Sans Amp so it's a little bit easier to find a clean sound. Yes, it is plastic, but I take care of my stuff so this is not a problem. This unit or the Tech 21 are excellent for passive basses. I can't play my jazz bass without this thing. It simply add punch to my bass and that warm sound that I really love to play rock. The other difference that I find with this and the Sans Amp is that the Sans Amp has a little more output than this but I just add more volume and bingo. The bass driver pedals add a little color to your sound so even when it has a "clean sound setting" it's a little hard to find a super clean sound so If you love a super clean sound, maybe this or the sansamp are not the pedal for you. Remember that this is a tube emulator. If you love a little warm sound (especially to play rock) you will love this unit.

Excellent value for money

Tube amp simulator with DI output.
I give it a 10 because it allows me to program sounds (like the VT Bass Deluxe). Given the price, I'm going too far, I know!!!


It's really easy to dial in, to be honest:
- A presence control ("brilliance," an enhancer)
- A drive control to dirty up the sound
- A bass control
- A treble control
- A level (volume) control
- A blend control (tube simulation rate)

The manual provides well thought-out presets.

I give it 8 because it doesn't have any mids controls, like the Sansamp Bass Driver it's a copy of.


The AF samples are excellent to get an idea.
I love its sound quality, it adds warmth to the sound and you can find whatever you want. I used it for reggae and slap and it's awesome.
No noise and many, many possibilities.
I got rid of it because I got a tube preamp but I sometimes miss this small magic box if only because of the ease with which I could get a killer slap sound.
I must say that I didn't compare it to the Sansamp but my opinion on certain Behringer pedals (the most recent ones) is that they are (almost) as good as the originals at a ludicrous price. The BOD400, apart from a slight difference in gain, is almost the same as the ODB-3 and the TO800 sounds like an Ibanez TS808 (although I must admit that I didn't compare these last two with the same instrument).
The only thing you can criticize it for is a lousy switch. But the BDI21 isn't conceived like the others and doesn't have a shitty switch (even if it wouldn't dare jump on it too vigorously!!!). The buttons are a bit loose, but nothing to worry about.


Test passed, considering the price.
If this pedal was sold for 100 bucks by a more renown brand, I'm sure many (including me!) would fall into the trap.
If you have an average amp, go for it.

Jazz Precision rather than ...

So it's a direct box. It can serve either as a direct box, or preamp, or emergency replacement if it was not his gear on hand ...

It is therefore an effect pedal format, which comes before amplification (hence the name pre-amp'...) der lol ... For specifications:

A level input / output level one ......
two parameters of equalizer settings: bass / treble
Can we find a "presence" (the goal is to increase the harmonics of the game)
Finally the "Blend": The wheel to increase the simulator lamp. The particularity of this effect is to bring a warm side to the sound without breaking the bank!
Then there is a footswitch / input and output jack "classical" / DI output for those wishing to enter directly into a table / Ground Lift switch to prevent ... I know not what? " A priori is to avoid the buzz in some contexts (neon, overvoltage, poor land taken ...).

I find the config complete and very well thought out. While the look is average, but at the same time a pedal AC arises from land, often in the dark, so ... For 30 € we will not ask for much more?

Of course not rackmount model ...
I think it's digital! Not light, but fairly convincing ...

XLR audio is connectable by the DI, or by conventional jack ...

It is regrettable that there have no marks around the knobs ... This is the only negative I find. The case seems solid (metal).


Setup: Simple! One branch ... Turning the level and it sounds! Course must be refined after!
Editing sounds takes a little time to find the sound that suits us, but we get a tampering his "inflated" more convincing ...

Manual? It is useless ... The only interest is to give two or three examples of classical sounds to try it at the beginning ...


This is where is the best! I think this little box is amazing! I was looking for a preamp box, and Noel, Father foo brought me this little box! What a great idea! Since December 26 I use it all the time ...
Initially I was using two types passive bass jazz bass. The advantage is a sound that is inflated, rounder, more "powerful" without breaking your ears ... It's warm, velvety, slamming against the side we criticize the sometimes passive JB!
I used preamp for concerts, and nothing to say! The macbhine done very good job. It gives me a heat lamp that I was not with my amp transistor. Certainly it's not real light. You do not compete with any Ampeg head lamps ... But for beginners it does it is!

This simulation lamp is a great idea! For cheap you can warm her sound! What cool ...

Face side: worries ... Well plugging in my old P Bass 79 (which has a large output level huge!) It was not going at all ... Well this is probably my settings! To me, they were perfect! And do it all again! Pwouah ... But it pretty saturated from the start. So I think it's a pedal for the rather low standard with modern microphones that send less than the old series. After maybe the P bass does not go with? Anyway for the jazz bass, there is a little warm side of the old low warmed to the lamp ...

The sound that I prefer:
- Drive: 9 pm .. To bring a hint of crunch ...
- Level at 15 h: to boost the output signal.
- Equa: as I am bass player: sharp at 10 pm or 11 pm to 14 pm and Basses
- The Blend: 15 pm, because at bottom it deteriorates too much signal ... It is the enemy of the good too.
- For harmonics (presence): I alternate between 12 and 14 h. Beyond that is too harmonic, below, the sound muffled sounds too ...

This is my setting, it is = Me, but I think I found a good compromise. After sometimes I play with the drive and the level to bring a small saturation very nice!

I put 9 for the problem with my P bass ...


I use it for 2 months. I am very satisfied, Father Christmas was the nose (without going broke !!!). Tried other models? No. on the other hand I tried the "real" tube preamp, and it's true we do not play very much in the same court! The sound is warm, sympathetic, etc. ... But it's still digital "simulates" a lamp ... It's not a lamp! So for some € you underfoot a small pedal that will improve your sound, amplifying the input, bring what I call a "smooth", a softer, less aggressive, some say plsu homogeneous.

What I like most? The box side to do anything! The side preamp, DI, equations, Boost ... For a few Euros! Obviously, if we have 200 € are a lot better. For those who can not, it's a great compromise: The sound nice without being discovered ...
The ratio Q / P? Unbeatable for what it's done ... After no limit if it is ...

Quite honestly, I would do this choice (Mr Noel finally!) Because I think it improves his record to have a practical tool that lets you move better sound at lower cost. And especially "his" sound anywhere!

After two months: it's always been on my amp, I use it every day ...

Excellent stuff!

It is an amp simulator pedal format which also DI.
Connectivity of + DI pedal.

Rgler allows the sound before the effects of renter directly to a table without an amp.


Simple Config.
In order
1) knob "drive" = fat is in the sound until a lgre disto.
2) Treble: I spend
3) bass: same
4) level: Determines the output level of the pedal.
5) presence: Ramna treble on the front of the stage but it is more subtle than a. .. In the limit of compression, I think. At noon that knob allows for a balanced sound and richer in harmonics.
6) blend: my prfr: simulation of lamps. A background! It


gnial. For a few dollars, that stuff turns your microphone or your amp lambda too "right" amp in "of character."

Obviously, it works not like Samsamp, but for Zikos bar or local festivals ... was enough even for real Zikos dsargents (I accumulate, arf!)

Only BMOL has lost a kind micro JB flt ct his easel and singing to add bass and potato. In short, fans of Jaco deprecated.

on the other hand, rockers of all stripes, and the rastamen slappeurs There's something ... For 15 euros secondhand ...

Intressant as a backup in case of roasting amp ...


Utilis past few months, I do more releases them. I advise everyone to get particulirement a round, serious, warm.

If you use a low entry level and / or an amp quite right, this beast will make you happy.

If you use a head lamp while Ampeg and Precision U.S., I do not know why you're reading this review. You can dispense with this pedal.
Frankly, is able to view the 10/10 low price, Obviously ...
