In Session with Al Schmitt, Part III: Vocal Recording Tips

A Few Tips From the Pro’s Pro
Al Schmitt has a career spanning more than four decades and hundreds of albums with everyone from Jefferson Airplane to Ray Charles to Diana Krall. The multi-Grammy winner is also one of the true good guys of our business—a generous soul always willing to offer his wisdom to others if asked. He’s worked with a few decent singers through the years: Sinatra, Jarreau, Dolly, Carly, Celine—the list goes on forever.

What microphones do you use for vocals? 
“On [jazz singer] Jane Monheit’s new album [Taking a Chance on Love], I used a Didrik tube microphone, which is built by hand by this guy in Sweden [Didrik De Geer] and there are only 24 of them in the world. Wow! It’s unbelievable! It’s also like $15,000,” he adds with a laugh. “[Producer] Peter Asher turned me onto it. We used it on Jane Monheit and it was perfect. She really belts it out, but she could not hurt this microphone. I’m sure I’ll be using one again sometime—it’s definitely special.”
Billboard's "Studio Monitor" column by Paul Verna
The Didrik De Geer microphone: In an era when craftsmanship has given way to mass production, it's rare to find products that are built by hand, one at a time. The Didrik De Geer microphone is one such item. Hand built in Sweden by De Geer, the mike is a jewel of design and engineering. Featuring a copper chassis and wood-carved bottom lid of ebony and jarra, and sonic characteristics similar to an AKG C12 (whence the mike gets its capsule), the De Geer is a $12,000 Rolls Royce - understandably reserved for the select few but stunning to behold.

I had the pleasure of seeing one of these babies at during a visit to veteran San Fransisco mastering engineer Paul Stubblebine's new studio, Paul's Gourmet Mastering - coincidentally located in the Bay area recording legend Wally Heider's old shop. Stubblebine's partner, David Denny runs a high-end equipment rental operation out of the former Heider complex, and he was brandishing a De Geer that was en route to nearby Plant Recording Studio for Metallica's use. Chris Isaak also used one on his latest release, and some fine live-to 2-track recordings were done in Europe using a pair of De Geers. With only 20 units in existence (De Geer can only make one per month) this is a rare and beautiful bird.
