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.

Tech 21 SansAmp Bass Driver DI
(Originally written by Thom_bass/translated from Audiofanzine FR)
DI with analog preamp in pedal format. Compact and sturdy product.

Very comprehensive connections.


Very easy configuration. You'll quickly get interesting sound results.

I only miss a mid control.

Clear and comprehensive user's manual.


The device is effective.

I used it with a 4-string passive bass and a 5-string active bass.

I mainly used it to add a preamp between my Fender JB RI62 and my Mesa. Unfortunately the sound didn't match my needs.

This pedal is mainly a DI box with a speaker simulation function. But you won't need it if you already have a good bass and a good amp.


I used it some weeks and sold it: I didn't really need it, besides it added a sound color I didn't like.

I previously had a PSA1.1 and I wanted a pedal again. But this product doesn't sound like the PSA (it's more like the RBI). I just couldn't find the sound of my PSA with the BDDI.

I never tested the RBI until now.

Average value for money: it's a good pedal but it's rather expensive.

If I buy something in this price range again I will go for the Sadowsky preamp/DI.

Tech 21 SansAmp Bass Driver DI
(Originally written by crrcrr/translated from Audiofanzine FR)

In general, I am very satisfied with the product's sound and connection options!


The SANSAMP makes wonders with every cheap amp.


It immediately makes every low/mid/top-range amp sound great. I had been playing with a Warwick Streamer bass + Little Mark F1 amp + Ampeg 4x10" speaker for years and the SANSAMP made wonders. But I changed my whole setup (Spector NS JH5 bass + EBS FAFNER amp + 4x10" EBS speaker) and now I can see its limitations so I don't use it anymore. The sound is a bit muddy, less dynamic and not accurate enough. But.. I plugged it into a Fender BXR200 combo and rediscovered the enchanting sound that motivated my purchase 4 years ago.


It sounds awesome with low and mid-range gear but there's no use for it with top-range systems. You should check if it's worth it for your setup before you buy it.

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!

MGR/vinnyp's review"Tech 21 Sans Amp Bass Driver DI"

Tech 21 SansAmp Bass Driver DI
Great DI and love the active option (sounds great!)!! I wish the 1/4" output(to run effect into my rig or mixer) was on the outside, instead of in the middle of the XLR and power supply(on front panel?). When using 90 degree 1/4" patch cables it get's a little in the way if you use the XLR at the same time. It has a input and parallel out in back, but using the parallel out doesn't give the effect to my rig (which sounds great).

Almost everything

Placement of unbalanced 1/4" output.


Good Buy @ $170

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.
