Jono Bolton Posted May 31, 2016 Share Posted May 31, 2016 After some issues at the weekend trying to mic up and EQ my amp for recording, it was strongly reiterated to me that I should buy a SansAmp for recording and as a DI for gigs. I don't quite have a spare £200 sitting about to buy the Bass Driver DI but I've heard that the BDI 21 is a good "clone". I probably wouldn't be inclined to use it for playing live, and most of the stuff I've read online is in reference to using it live, but as a DI for recording and tone shaping, is the BDI 21 good enough? Will it give me a convincing amp sound as I've recorded going directly in to the desk before and it always sounds quite lifeless, even with an EQ added with the recording software.

discreet Posted May 31, 2016 Share Posted May 31, 2016 Yes, it's good enough. I've used one for recording with great results. I've also gigged one with great results. Don't be put off by the low price or the fact it's made by Behringer, it's a good bit of kit by anyone's standards. Quote Link to comment Share on other sites More sharing options...
paul_5 Posted May 31, 2016 Share Posted May 31, 2016 Yup. The blend control is your best friend, but they perform brilliantly as DI boxes for live or recording work. Quote Link to comment Share on other sites More sharing options...

[/quote] Yes, and don't have the bass and treble up full or you will lose your mids. For more mids back off the bass and treble. The unit works best (for me at least) with quite subtle settings. Just having the thing in the signal path makes a big difference. Edited May 31, 2016 by discreet Quote Link to comment Share on other sites More sharing options...

[/quote] Yup, especially as the 2 band EQ is applied to the clean signal as well as the dirty signal, so if you crank the bass and treble then ALL of your mids disappear, not just the overdriven part of it.

Lozz196 Posted May 31, 2016 Share Posted May 31, 2016 In the studio we recorded at the engineer got me to play through a Sansamp - essentially the more expensive item that the BDI21 was modelled on. His advice was get all of the required sound/eq from your amp, and then put the Sansamp (so subsititute BDI21 there instead) in the line with everything set at midday, and then adjust blend to suit. This is the way I`m using my BDI21 on my home practice set-up, as well as my Sansamp on my live rig. Have to say, it works a treat. Quote Link to comment Share on other sites More sharing options...
rmorris Posted May 31, 2016 Share Posted May 31, 2016 (edited) Basically - get a BDI21 - it's pretty much the Sansamp BDDI soundwise. Different Opamps but none the worse for it imo (I have both). It doesn't work from Phantom Power and may be a little less rugged but comparing the price when funds are limited the choice is obvious...Both are something of a Swiss Army Knife for Bass Sounds.

LiamPodmore Posted June 1, 2016 Share Posted June 1, 2016 I ended up replacing mine with an MXR M80 but it still works fine and still does the job. For £20-£30 it's more than up to the task. Quote Link to comment Share on other sites More sharing options...
Muzz Posted June 1, 2016 Share Posted June 1, 2016 Yup, I've just bought another one as a backup - never had an amp fail on me live, and I don't need the sound help with my amp, but now I've got one in my gigbag, I'm covered. With previous amps (LMIII, etc) I've used the BDI21 and the full-price Sansamps, and had great results. There's a link to a great price on them somewhere on here, too...

M@23 Posted June 1, 2016 Share Posted June 1, 2016 I've had mine for two years and not used it once on a gig! It's the backup option which hopefully I'll never need. Did use it once for recording and it did a surprisingly decent job! Quote Link to comment Share on other sites More sharing options...
mr zed Posted June 7, 2016 Share Posted June 7, 2016 Can the BDI 21 be used successfully for impedance matching of a double bass pickup? Looking for a cheap option. Cheers. Quote Link to comment Share on other sites More sharing options...
paul_5 Posted June 7, 2016 Share Posted June 7, 2016 Dunno. A quick glance at the manual reveals that the input impedance is 1MΩ, output (1/4") is 1kΩ and the balanced out (DI) is 200Ω, so I would imagine so, depends on the impedance of the DB pickup though, but I can't see it being greater than 1MΩ.

[/quote] Thanks Paul - also need a pickup. The J-tone is nice and cheap and seems to be well regarded. I'll see if I can find the specs.

Looking for a cheap option. Cheers. [/quote] All depends on the pickup and what type it is. I'm guessing it might be a piezo type. If so then it'll work but many people prefer the sound of a piezo transducer working into a very high impedance which might well be > the 1MegOhm that the BD121 appears to offer. Having said that, this is often discussed wrt guitar pickups - with a DB it might not be an issue ? Worth a try imo. Quote Link to comment Share on other sites More sharing options...

The Behringer holds its own against all the others. The core tone of each was actually quite similar. If the same pedal was not a Behringer and not a 10th the price of some of the others, it would probably be lauded on its own merits. Quote Link to comment Share on other sites More sharing options...

With all the controls at 'midday' there's a significant change in the tone compared to 'bypass' (when it does act as a 'straight' DI ) Quote Link to comment Share on other sites More sharing options...
bazzbass Posted November 18, 2016 Share Posted November 18, 2016 yeah it does scoop the mids by design, the new Tech21 one has a mid control now I believe What you want is the Tech21 VT but they're expensive too Just get a VT pedal (not the DI) and buy a DI for fifty bucks/euros/pounds maybe? I like the VT so much I have v1 and v2 side by side on my board Quote Link to comment Share on other sites More sharing options...
rmorris Posted November 18, 2016 Share Posted November 18, 2016 Really just get a BDI21. Try it. If it doesn't suit move it on and you won't have lost out much cash anyway. Quote Link to comment Share on other sites More sharing options...
A.G.E.N.T.E. Posted November 18, 2016 Share Posted November 18, 2016 (edited) +1 on the BDI21, and i also have the VTbass. The behringer is great pedal for the price and at the studio will get the job done. Never giged mine but have it since 2005, for home practise and studio. Still working fine. A couple of years ago i ´ve done the "mids mod" and i found it a really nice upgrade. Edited November 18, 2016 by A.G.E.N.T.E. Quote Link to comment Share on other sites More sharing options...
bassmachine2112 Posted December 31, 2016 Share Posted December 31, 2016 Hiho,BDI21 ,great pedal-got mine S/H 10 years ago for £6.I use it live in front of amps,DI to PA without an amp as well as record with it. I do 100 or so gigs a year and practice on top.It,s never missed a beat. I use this all the time even open mic/jam nights that,s how good it is . For the price it,s a no brainer and I cannae stand that phrase but it really is. Quote Link to comment Share on other sites More sharing options...
Maude Posted January 1, 2017 Share Posted January 1, 2017 The acoustic version (red one) works well with bass and has a mid control. 1 Quote Link to comment Share on other sites More sharing options...
