I have an OCDP kit.. the basswood kit to be exact. I use the D4 on my 16'' floor tom with evans EC2 heads and it sounds AMAZING. We just recorded a song that sounds really ambient so we needed a heavier sound from the toms. You can really hear the resonance but it still has that good soft punchy sound.

And best of all, it looks sweet. It's got the red inside of it.

I have been playing for years without satisfaction. However this mic even when the board is all the way up, with a signal booster in a cramped room with guitars and amps all playing, got no feed back at all and when I stepped in wow. the overall ambience was outstanding. this is the mic you want to use if you are not using a clip on. I don't know what can beat it. I have been a AKG man for a long time, but this one is the real deal!!!!

I've been using one of these on kicks for over ten years now, ever since an old bandmate left one of these at my place and then moved away. I've never upgraded to a 'real' kick mic because I've never had to compromise with this mic. I wouldn't recommend it for kick in harder rock situations, but anywhere where a tight sound that borders on the low mids is in order (pop, indie rock, etc), this is a great mic for kick.

Also, i've used this on its more intended sound sources such as tenor sax and bass cabs and it works wonders. All the past comments about not having to add eq are spot on, this mic has a great sound.

I've been trying all the mics in my closet on my upright bass. For recording, the AKG 414 sounds great but isn't an option when I play out on stage. I saw a setup on a site devoted to bass where a guy covered a shure beta 58 in foam rubber and jammed it under the bridge of the bass with the screen right up against the body. Rubber bands attached to the bridge held it in place. I tried it and and the sound was pretty lame. Then since the Audix D4 is much shorter, I tried the same thing. Bingo, excellent sound that I would never have expected, especially since I would rate this mic just average as a kick drum mic. It just needs a lot of gain in this upright application, so an amp, board or piece of outboard gear with good gain on the front end is helpful.

I have used this mic for a while, and really enjoyed it for bass cabs and baritone sax in the studio. It was good at recording high SPLs for extended time. I loved it all around until I went out and spent the money on the D6 bass drum mic. I recommend that for the additional 30 bucks (20 if you are lucky), it is well worth it to go for the D6.
