Double Bass DPA 4099 vs AMT SP25B

For a while, I was using Obligatos on the G and D, and Flat Chrome Steels on the A and E.

About 2 years ago, the G snapped on a gig. I had the G and D FCS in my case, so I replaced it. I decided that I liked the FCS G string better. I may get around to swapping out the D one of these days.

Thanks to all for answering my questions.
I am going to order a DPA soon. I've sent an email to mike, but I didn't get an answer yet.
The Ric Vice idea of putting it in the tailpiece looks great. It seems pretty similar to the tailpiece mount of the AMT.

Thanks again,

Damian

Damian,
NickyBass showed the mount on this thread. I can't take credit for it.

Sounds like the 4099 is well-liked. I'd like to get one, but my concern is with the frequency range starting at 80hz. I read all about the high-pass filter vs. flat debate, but isn't it a problem that the mic doesn't pick up a whole octave of bass frequencies? I listened to the sound clips much earlier in this thread and the low-end sounded pretty thin to me, but it could have been the bass.
What say all you 4099 advocates?
 
well, the easy solution to address your issue is to order it with the flat adaptor, which i understand you can do know for no additional charge.

i gotta say, though, for most live situations, i don't think it matters much.

The frequency range doesn't start at 80hz - the frequencies below 80hz are merely attenuated. When the mic is placed close to the top of the bass the low frequencies are boosted due to the proximity affect so the end result is a somewhat flat frequency response. I did find the 4099 to be a little thin until you place it in really close, but that's exactly what you need for live applications.

Yes, I certainly agree with that. When I got mine I couldn't buy a flat version without paying extra for a separate adaptor. But in my conversations with the UK distributors they pointed out the need to roll off some bass due to the proximity effect. And this is borne out in the mic's performance. It is well known that the highs lose their strength the further away the listener sits, while the lows tend to take over. So for live applications the attenuated DPA suits me fine. I do sometimes blend in a bit of Underwood tho. But that's for me!
 
Thanks, guys. That clears it up for me. I asked DPA the same thing and they said they couldn't guarantee a certain dB level under 80 hz, but that the mic would still pick up frequencies.
I just ordered one with the brand new bass clip. Everyone seems to be saying that you need to buy an adapter to make the signal flat, but my impression from the graphs on their site is that the mic is flat and the optional DAD 4099 adapter has the high pass filter. Perhaps they made a change at some point?
Any recommendations for cheap, but good enough, preamps for this thing?
 
Slightly off topic, but I played up in Cincy last weekend and ran into bassist Steve Whipple there - nice player. While listening to his set, I noticed his sound was very natural and organic. When I asked him how he was amplifying, he told me he was using a DPA 4021 omni attached to the top beneath his bridge though the house, no amp. It was a little on the quiet side for me, but the sound was very natural and clear. He got no feedback with an omni mic attached to the top while standing next to the drummer.

This DPA stuff must really be something else.

Still a bit off topic, but....
Sorry for this late response, but this is the way the great Danish bassist Mads Vinding mikes his bass both for live and studio performances. And IMHO his sound is always great, as well as the playing of course....

Oystein,
Using a mic on my bass always sounds better than the pickup. If I listen to the instrument using only a DPA 4099 or the AMT or even the Crown GLM mini condenser into my amps, it's more like the instrument and it's easier to play. Unfortunately, this doesn't always work in all the different playing situations I end up in. I think that with the new DPA 4099 we're getting closer a mic that is so discrete you won't need a pickup, but were not quite there yet. I looked at the DPA 4021 but at $1,750.00 it's out of my price range considering the possibility that I might damage it by tripping over a wire. Something that I've been known to do ocassionally :p

I totally agree with you when it comes to pickup vs mic sound. I have the AMT right now, had the crown mini condenser earlier and wonder if I should swap the AMT with a DPA 4099b, the DPA 4021 is out of my price range.
In live situations when running both Fishman Full Circle and AMT through my amp I always end up with more pick-up than mike signal due to the volume.
For those of you that have tried both, does the DPA 4099 go louder before feedback than the AMT?
 
im very sorry to DO this, but i just went through the thread again and im having trouble finding out how to order one. i could swear i had read a post with an email to use to put an order in, but i cant find it now.

i also went to the website but they just have a distributor list and that doesnt help me where im located.

help!
