OVERVIEW

There are DI boxes and then there's the BDI21”the feature-packed analog DI box built especially for bass.

The BDI21 combines the features of an active DI (direct injection) box with our proprietary tube emulation circuitry. Its like having a truckload of vintage tube amps right at your toes! The Blend control allows you to mix the amount of tube emulation you want with your direct bass signal. And if you dont want to use the tube emulation feature, just step on the switch and the ADI21 functions as a superb active DI box.

With its dedicated DRIVE, TREBLE, BASS, LEVEL, and PRESENCE dials, the BDI21 DI box goes above and beyond, giving you vintage tube tones for some funked-up slap, gonzo overdrive and everything in-between. You can use the BDI21 as a recording output DI, with tube emulation, or as a standard active DI box, when running in bypass mode. The output is laid out on 1/4" TS or balanced, gold-plated XLR connectors. There's also a ground lift switch that eliminates typical ground loop hum problems. You can power this bad boy with a 9V battery or our PSU-SB DC power supply (not included).

When it comes to DI boxes, you can go with simple injection, or plug into the BDI21 to add some badass tube-like fuel injection to your bass.

FEATURES
  • Analog modeling bass preamp/stompbox with DI recording output
  • Designed to compete head to head with leading products on the market
  • Authentic V-TONE modeling technology capable of dialing up big vintage tube tones, funky slap sounds, crunchy distortions and all in between
  • Provides a truckload of great amps in a single stomp box”from traditional bass amps to modern overdriven amp tones that would typically require a multitude of effects units
  • Authentic tube emulation circuitry can be mixed with the direct bass signal via blend control

I was able to dial in a decent bass tone with little fuss right away. Fattened up the tone on my little practice amp. I plan to use the mic out for a mixer for rehearsals and/or shows, but I haven't tried it out yet. The unbalanced out sounded pretty good through the amp, though. The blend knob add some noise when dimed - need to back off on it a bit. I had an SA guitar pedal back in the day, but was never able to get a good guitar tone out of it. I can't speak to the guitar version of this pedal, but I'm like the BDI so far.

I agree with others that the switch is questionable. Feels too much like it switches via transistor and not at the switch (if that makes sense), and takes some pressure to engage, which worries me. I would prefer a good old fashioned standard DPDT, or whatever. But handwired these are not. Not a biggie, but I won't be switching much if I don't have to.

Fairly easy to use. Although, the instructions are minimal. In fact, the included instructions were better suited for the guitar version (illustrations has all the mic settings - like the tech21 pedal - which are not included on the bass BDI). Overall, a good buy. Does it needs to do without minimal tweaking, and low cost. Winner!

Obviously with Behringer you are likely trying to save some cash instead of getting something "name brand." When I would record DI bass guitar, I used to run it through a distortion or fuzz pedal to get a more natural sounding gain. The V-Tone pedal is very good in that regard. Turn the presence, drive, and blend knobs all the way up and adjust the EQ to your liking and you get a mean crunch while keeping the clack of loose strings.

That is about the limit of this pedal's potential, at least for me. Any adjustment to those knobs to turn down the distortion results in a sound nearly identical with just a clean DI with no pedal or preamp at all. It's as if turning them up from 1 to 8 has no effect until you get them to 9 and 10.

Another flaw I've found is the high gain settings bring along a high pitched whistle that occurs randomly during playing, though it seems to happen with a lot of string rattle from long, held notes. It doesn't stand out when it's mixed with drums and a wall of guitars, though.

I've only used it as a DI for recording, never as a preamp or DI for a PA or anything like that, it's possible it could be really good for those. I am happy with it to record bass for my doom, black metal, and mathcore kind of music, but wouldn't go to it for anything else.

Comments about Behringer BDI21 V-Tone Bass Driver Bass Amp Modeler/Direct Recording Preamp/DI Box Pedal:

The pick-ups on my Squire are weak. The BDI21 gave me the volume and tone I was looking for at a great price. At one of my gigs the house PA system is weak too, the V-tone gives me great bottom end with no distortion even when playing through a cheap PA

Not that great

About Me Professional Musician

Comments about Behringer BDI21 V-Tone Bass Driver Bass Amp Modeler/Direct Recording Preamp/DI Box Pedal:

Behringer is definitely an entry level product, This particular piece however, is below that. Yes it will color your sound, and yes it will make your bass louder, as well as increasing the hiss in the signal chain... Wildly. The "level" knob is useless. If you turn it up at all your bass rig will start to REALLY HISS, but the bass tone seems to stay the same. I tried all of my basses through it.. Same result. I took it back the next day. I like Behringer products. They are cheap and for the most part, do the job. This one is just TOO NOISY. This pedal should be called an EQ, With a HISSSSSSSSSSSSSSS Booster.

    This is a great little DI and Amp especially for the price. I got the mellow Bass sound I was looking for. No hiss or hum. Lots of features in one little compact box.

      Comments about Behringer BDI21 V-Tone Bass Driver Bass Amp Modeler/Direct Recording Preamp/DI Box Pedal:

      I needed an inexpensive bass amp solution for our church setup. I run the XLR into the board and the 1/4" into a keyboard amp as a stage monitor. Great sound live and it comes across nicely in the recordings too. Excellent tool for the price tag. I'm looking forward to using it in my home studio. My next purchase is the ADI21 for my acoustic.

      For fun I plugged my electric guitar into it. I cranked the gain and set the tone controls at noon and it produced a pretty cool vintage tone. It won't replace your vintage Bassman, but it would work nicely for a home jam session.

      Pick this thing up. It's a bargain!

        Comments about Behringer BDI21 V-Tone Bass Driver Bass Amp Modeler/Direct Recording Preamp/DI Box Pedal:

        I use this in front of most any type of bass amp. I have a few GKs of different sizes for different gigs with the treble and bass pulled way back. Anyway, I have more than one of these little boxes so I can keep one in each bass case so I won't accidentally leave for a gig without it. I run it gain dimed, blend dimed, treble all the way off and bass all the way off since it has a natural scoop I don't really use. Presence acts a lot like an old school tone knob, which also brings in some top end grind without losing the girth. With a jazz bass or Ric 4001, it gives an Entwistle/Squire/Lee kind of drive and natural compression that squawks pleasantly if you dig in. I don't switch it on or off - I just use it like a preamp on all the time - with maybe dialing more or less of the presence knob and nothing else. This thing sounds astounding in front of an old Acoustic 370 at full steam, but it's also astoundingly loud in this setup.

        Comments about Behringer BDI21 V-Tone Bass Driver Bass Amp Modeler/Direct Recording Preamp/DI Box Pedal:

        I got this thing to DI bass into a board for home jams (see jamhub) and recording. This thing does a great job of emulating a nice bass amp tone. The switch seems delicate, but it wont be a problem because the dry signal sounds terrible, so it'll always be on. Great value, to get better sound quality you'd have to spend 4-5x the cost of this unit. FYI it does NOT come with a power supply.

        Comments about Behringer BDI21 V-Tone Bass Driver Bass Amp Modeler/Direct Recording Preamp/DI Box Pedal:

        I have used this many times in front of my amp and direct to the PA in place of an amp. I just put the bass through floor monitors in that case It colors the sound some to fatten the sound and keep it from sounding dry as it would with a straight up DI box. Also makes it so you can boost if need be to level out two basses you may play in one night. I use it with my electric basses, acoustic bass and upright electric bass. It quietly turns off and on when you stomp it. I marked where I like to have it with a Sharpie and I put a white dot on the dials with a paint marker so you can see where it is set in low light. The Behringer adapter is not too good and a one spot won't work. The Behringer adapter works, but doesn't seat in the plug as you would expect. It is quiet when turned off. I like it and have used one for at least seven years. I bought one as a backup expecting the inexpensive pedal to eventually die, but have never needed it. I have recommended it to friends and the ones that bought one agree with my assessment.

              Every bass player should have one of these in his/her guitar case - in case of amp failure, use it as your spare amp directly into the board - or if the venue is so small that you can't put up your "big" rig, use it straight into the board. It works great, reliable and good sound - no bells and whistles. Yes, everyone should own one.
