Michael Bublé – Christmas

Humberto Gatica, who produced Bublé's "You're Nobody Till Somebody Loves You" and "Stardust", states that "with Michael I use a vintage tube Neumann U47".

Al Schmitt, who produced It's Time, Special Delivery, Christmas, Nobody But Me and Love, stated in this July 15, 2015 interview that he also used a valve-based U47 with Bublé:

The U47 – that’s the one I used on Bublé, Paul McCartney and so many others. (...) For Diana Krall and Paul McCartney (and others) I used a Neumann Tube U47 into Neve Preamp and then into a Fairchild compressor. That, to me, is the ultimate.

Lastly, a valve-based U47 can be seen throughout various "Studio Clip" videos on Bublé's official YouTube channel. Its label can be seen up close in this video for Bublé's cover of Mariah Carey's "All I Want For Christmas Is You". The label reads "M7 Capsule Nov2006", offering that it contains the M7 capsule typically associated with vintage Neumann U47s.

"In terms of microphones, I had a (...) [Neumann] M50 for the ambience.

(...) I like to have options of close, section, and ambient microphones. The room at the Warehouse has an interesting height, and I put the M50 up at the balcony, and also put up two [Telefunken ELAM] 251s as ambient mics, just to fool around and check the frequency response up there.

(...) I mainly use the GML EQ and the Neve 33609 compressor, but very sparingly. I had both boxes on Michael's voice, and some reverb, and another EQ, that I don't want to talk about. I'm supporting kids that go to college!

(...) For ambience I of course used the ambient tracks that I had recorded at the Warehouse, mostly from the M50. I used two other stereo pairs of mics, because I'd never worked in that room, and I wanted to cover my back. But there was a resonance in the air that was fabulous. I had the precision from the close mics, and then when you open up the room mics you get the depth. I also added some outboard reverb from the live chambers at Capitol. They were amazing. You can't top that.

(...) I'd make stems of the saxophones, the trumpets, the rooms, the bones, the drums, the snares, the vocal dry and the vocal with reverb."

Used as an ambient room mic for "You're Nobody Till Somebody Loves You", as mentioned in this Sound on Sound article.

"The first thing I do when I begin a mix is work on the vocal. I make it sound smooth and make sure the articulation is correct, and so on. I spend a lot of time making sure the vocal is in top shape, and I may use a little bit of Neve 33609 compression and my GML EQ — the GML is one of the most musical EQs ever built. Everything has to revolve and sound good around the vocal. When I've gotten the vocal to sound right, the foundation is there, and the mix becomes more fun and there is room to be creative and expressive with the rest of the mix.

(...) With songs that I have recorded myself I don't need to do much in the mix, it's more just a matter of balancing and placing things in the stereo spectrum.

An image of the console, which offers the features that distinguish it from other versions of the 33609, can be found here from the same source.

"There are some great-sounding new records, but in the past we made better-sounding records, with more soul. The higher sample rates help, so I've tried using 96k, but it's a pain. It uses too much space and slows down the session, and I like to move fast. So I'm now back to 24/48. I still think that the converters of the old Sony 3348 [digital multitrack tape machine] are incredible. When I worked on Michael's albums at David Foster's studio, we always went through a 3348. For my current studio I bought an old 3348, and I process my signal through its converters."
