Tech 21 SansAmp Bass Driver DI
Tech 21's Sansamp Bass Driver DI is an awesome little box that offers both the flexibility of a direct input box, and the sound and control of a pedal. This is an analog piece of gear that has 1/4" connections for an input and two parallel outputs, and it also has an XLR output. It can be powered by a nine volt power supply and isn't rack mountable as it is controlled by your foot.


The make up of the Tech 21 Sansamp Bass Driver DI definitley makes it quite a flexible piece of gear. It can be used for live shows or in the studio, but I've only used it in the recording studio. As far as parameters go, it's got knobs for level, blend, treble, bass, drive, and presence, as well as a switch for phantom/ground. It then has a switch to engage or disengage the parameters. A manual shouldn't be necessary for most users.


Both as a traditional DI box and as a pedal, the Tech 21 Sansamp Bass Driver DI excels when it comes to sound quality. I love the sound of this when used as a simple DI box, but when paired with it's ability to be used as a pedal, the palette of sounds increases exponentially. You can definitely get a good sounding drive with this for when you might be looking for some more crunch and not just a clean DI signal. I've only used it with bass guitar - a Fender P Bass, and since it is designed for bass I don't think that I'd recommend using it for anything else. Although Tech 21 does make other similar devices for non-bass instruments.


The Tech 21 Sansamp Bass Driver DI is really the perfect combination of a DI box and an in depth bass pedal with a lot of control over your sound. I'd recommend that every bass player look into this, as it will definitely add a lot to both your live rig and in the studio. Studios should also consider having one of these around, as its the perfect one stop shop for recording bass guitar direct. All in all, deifnitely a reliable piece of gear with a great sound and a lot of flexibility.

MGR/Golem's review"Tech 21 Bass Driver"

Tech 21 SansAmp Bass Driver DI
$89 used at Guitar Ctr Albany NY.

Had gone to one of their clearance
sales and was just browsing around.

I knew Tech 21 NYC stuff is very OK
because I'm already using their Bass
Compactor, a compressor with EQ.

It is both tube simulator and a DI box.

I know what my Fender Bassman tube amps sound like, and know their limitations.
The Bass Driver is a decent mimic, not
quite 100% fool-your-ear, of the Bassman
sound, but it can produce that tone over
a much wider range of volume levels and
at any level of drive-effect you choose.

The Bassman itself increases the drive
sound linked to increases in volume that
are not always appropriate for the venue
or the audience. The Bass Driver solves
this dilema and I find the trade-off [of
very slightly "inauthentic" tube sound]
to be well worth the greater flexibility.

It has a 2-knob EQ [bass & treble] but I
find that the "mid" knob of any 3-knob EQ
is my most valuable control. This is not
really a limitation if the bass that I am
playing has a midrange EQ control; and if
the bass in use has only a single passive
tone knob, then even the 2-knob layout is
an upgrade in tone control.

Like all Tech 21 stuff, rock solid. USA
built with heavy metal exterior, solid
punch-button type of foot switch, very
quiet [super-low background noise].

Has a 9v DC input, or runs from Phantom
Power when using its XLR output jack, or
runs from internal battery.

Also has 1/4" output, plus another 1/4"
out for dry [bypass]. The 1/4 and XLR
outputs of course carry a user-dialed
mix of wet and dry controlled by a blend
knob. There are also knobs for overall
output [dry bypass jack not affected],
for drive intensity, and knobs for bass,
treble, & "presence". Presence adds a
lot of finger noise if you dial it above
the 1/3 position [with roundwounds].

Clean overall gain is less than from any
other pre-amp that I've tried [Fishman,
Baggs, and Aguilar] since this is really
a DI box and not a pre-amp. However with
a medium amount of drive, and some boost
on the bass, it's about the same level as
an outboard pre-amp.

This is a very useful, flexible device.
That comment despite my general attitude
that effects are for losers!! I don't
care for anything that masks or that even
transforms the instrument's voice. But
in truth, even your choice of amplifier
somewhat transforms the voice of your ax.

Before you trade your light-weight solid
state amp for some monster tube amp, you
owe it to yourself to see if this box is
all you really want or need. Do be aware
that it might shred a cheezy speaker, but
it can turn a decent rig into a great one.

MGR/George Pallotta's review"Tech 21 Sans Amp Bass Pre-Amp Stomp Box"

Tech 21 SansAmp Bass Driver DI
If I was allowed only One Stomp Box Effects formy Bass Guitar, the Tech 21 Sans Amp would be it. This little Box blew away all the other Mono and Multi-Effects Modules I hooked my Bass into. It is very versitile, it allows you Funk and Fwap to R&B and Jazz and Drive Home the Bass line in a Heavy Metal Song with the "drive" knob. Turns your Average Bass guitar into a High End Bass with Rich, Full, and Solid Bass tones.

Paid about 170.00 at an Online Musicgear site.


Solid, Light Metal Contruction.

It is simply the only Bass Effect Stomp Box you need to own!

Tech 21 SansAmp Bass Driver DI
see doc or other notices
connection options than sufficient for most uses. Switches impedance for both outputs (XLR and jack) + auxiliary output allows all conceivable configurations.


Easy to use when you control the dosage levels of input / output and that makes the difference between treble and presence. The lack of medium poses no problem because I can sculpt the sound around, + or -. The blend is super important: do not ride too much not to distort the original sound of the instrument.


just put all the knobs at noon for MIDI at the extraordinary improvement that gives the pedal sound. Then, for my part, on a passive bass (fender precision), I drop a little blend before plugging in my Ampeg (twitter disabled). Live PA, or amp to twitter, I fall a little more treble. It enhances any configuration.
I use it with a Fender Precision, a sting ray 4 and 5 and a fretless yamaha trb. Compared to the Sadowsky preamp, it sounds more warmly at the expense of the clarity of sound and it suits me like that. Nevertheless have a very flashy sound playing on the settings you can.


I use since 1998. She has never left me. I changed my sets many times but it was all adventures. Currently I use it only with a cry baby bass.
Only negative point: poor bore the XLR jack which makes it unusable. I have not found other evidence of this type so I guess I'm the only one it happens ...

with the experience I would definitely choose this indestructible gem.

Tech 21 SansAmp Bass Driver DI
Everything has already been said it!


No better


In overdrive or clean tone, it sounds serious! It turns my combo rotten (my first Peavey 60 watt 96) more honest combo (it does not work miracles but still not!). My bass is an entry-level 96 ditto Transfer on which I had mounted Bartolini pickups JB replacing original. Ben and the BDDI sounded roughly the better! This is stunning! On my stack (always with Preamp Peavey Tmax, 1 box 1 * 15 2 * 10) with the same combo ben ...


How long have you been using? 16 (cow already!)
Did you try many other models before buying it? No, it was all about control, confidence on the seller as well as ducks Mag Bass style 'and Guitar & Bass!
What is so special that you like most and least? most: the sounds, longevity (concerts in bars from 96). Cons: it is not coffee.
How do you rate the quality / price? good.
With experience, you do again this choice? Yes, but I feels for giving me the VT deluxe! If someone has had the opportunity to try both, if he can give me his opinion ...

CautionHot's review (This content has been automatically translated from French)" Oh yeah ..."

Tech 21 SansAmp Bass Driver DI
The Tech21 American firm proposes a preamp / DI analog simulating USA made several very interesting sonoritées type (SVT, classic tube ,...) with an incredible quality.
The pedal has a switch, an XLR jack, an input and output and an output parallel output. The recording studio will be little difficulty through the small switch (settings of the DI) to manage perfectly sound. Use of this


SansAmp is remarkably effective through the manual (although delivered in English .. But hey, these days, which is not really bilingual?).
The manual offers some examples of settings more or less interesting.

Note: The setting of "Blend" is constamenent settle firmly into the
Sample Hors ... this is not mandatory


sonoritées issued by the preamp / DI is amazing, moving from crystaline sound, very low distortion with a little fat, husky .. So the possibilities are many.

There are 2 disadvantages of this pedal unfortunately:

1. The lack of a midrange setting .. Who Will could push the "Holy Grail" in his last retranchement.L use a pedal (or rack) of equalization will be crucial if the key to your sound.

2. Strong pronunciation of low-medium: low volume pot goes to around 120Hz, which makes the sound a bit dull and frankly not musical (the low setting would have been better if it had been made between 50 and 80 Hz).


I play with a Jazz Bass D'Addario ProSteel mounted with pick (sometimes not) directly into a Hi-Fi amplifier, guitar 5Watt Class A tube or directly into a PC.

I did not try other models preamp / DI the amp but this pedal that simulates (Ampeg etc.) and I must admit that the sound is almost the same (different parameters taken into account).

The additional use of pedals such as a limit / equalizer / compressor etc. will make the most versatile sonic possibilities.

Paid 249 euro ... Made in the USA, a real preamp / DI analog ...

What else?


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

Tech 21 SansAmp Bass Driver DI
beefy little box, analog simulations are very nice and many opportunities to find or sought SONS.
Initially it's a DI with XLR and JACK choice.


the manual is in English (I'm terrible) but the chart with 12 positions of my settings enough to understand.
No editing is possible but all that simple.


simulations are immediately effective and surprising.
The realism I do not know, not everything in memory, but it gives very specific grains.
I use it mainly with JB STD 94 U.S. and Cort NB4FL so much as.
I do not use an amp on stage so direct power mixer Yamaha GF16.
among the 12 simulations suggested there are 5 that I have chosen and interresting:
KING 'S STYLE (saturation)

other simulations and sounds distos does not m'interressent and simulation REGGAE I find anywhere


Actetée used on AF 145 roros super state, and I use it for a few days (1 repeat).
So about 100 roros cheaper than new.
I have not tried other preamp (not found in 2 stores in Grenoble), simply followed the advice to AF.
The choice is not easy at Tech 21, but being a follower of AMPEG it seemed that this model will fit well and it is certainly better vrai.Il .... but too expensive to risk.
And yes the price is important, not too expensive and used for not regret and especially salable stuff and recognized, it is my principle too.
So the first review Q / P: TB case on occasion, nine no opinion since not compared to other preamps.
For now it's more than enough and with time I will certainly find other simulations interresting. I think when I mastered I go to resell it for programmable model.

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

Tech 21 SansAmp Bass Driver DI
Low Prampli exceptional trs frankly, boost bass / treble; prsence; blend; drive.

Simple and intuitive, a marvel for rcuprer sounds "lights" type Bassman, Ampeg SVT.

The possibilities are extremely varied because of the sensitivity of rglages.

Three outputs for supplying an Amp and two sources of high quality DI.

Small but burly trs every respect.


We groped a little beginners to find the quintessence, the online manual gives a lot of examples of sounds and your exact trs is soon to go.


Really top stuff for a price drisoire enough in view of its quality (almost new bought mine for 170 without power).

And especially with no breath rglages "reasonable".

Staining "hot" and "clean".

I only see the Aguilar to compete in quality but with less versatility ... well I do not know everything either!


Bought a year ago, and unavoidable since it feeds my Roland DB 900 and my Fender BXR 300 sets, the sound is standard and trs clean, but easy "dirty" if necessary with the drive.

stf74's review (This content has been automatically translated from French)

Tech 21 SansAmp Bass Driver DI
Enough said.
(Even the lack of a knob for medium)


Hack is 5 minutes from the amp or the PA and boîboîte and gives her a nickel or XLR jack.


Good range of sounds, from fat to slamming.
On my SansAmp the addition of drive adds a lot of background noise and must juggle all the elements connected.
It must also set the amp, it can quickly saturate. (I may be a little nag)


This little box is ge nial e. Me too it saved my life in rotting horse on amplifiers or sound systems on at various events in the woods. A Swiss Army knife as a consultant in its gigbag. It's like the trombone MacGyver is bluffing.

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

Tech 21 SansAmp Bass Driver DI
Bon ben t say it all. I bought it used and I do not count me Sparer ... prcdemment as said, this gadget could save your life and given its size and the sound comes out, I put 10.


Operation is very simple and intuitive trs. Used as prampli or effect of boost / drive, it can be a juggle between the bb and the amp ... but sr is to have a sound that kills.


I use a Fender and a Fender Plow amricaine JBass Japanese. Personal I use a Warwick amp ProFet 4 in a rock band 70's. I post a notice on this little critter logieux (the so ProFet 4) but with the Bass Driver ass is joy. There is grain, high-sounding bass, treble prcis but do not dchirent eardrums ... the finger and the game is very well made. In the mediator can play any style greasy without problem.
Note that the sound is trs US East.


Well, the trick with the Bass Driver fabulous is that one is sr to have a good sound. If the amp breaks harbor, we can directly plug into the sound system. If it is a combo prter Park musty falling apart for the village fte Moisy-sur-Bolet is our little branch Casing top and boom! We can start laughing. He dj save 1 time in concert and it magnifies my rack all rotten. I do it again this choice with his eyes closed.

Add APRS change gear at all for Ashdown (MAG 500 EVO II MAG414): I joined a new group east stoner-garage-punk-hardcore that has little do with my other group of jazz rock kind. I have invested in new gear (the Ashdown) and I put between my bbte US Plow and my amp ... I sound just incredible power and without the quality of my head are dnatures. As a speaker cash trs well ... Graouh! It confirms the potential and flexibility of the contraption.
