Studio Microphone Selector and Switcher

The Gold Digger™ is a 4-input, 1-output switcher that allows you to seamlessly audition multiple microphones through a single preamp, improving studio efficiency and workflow without altering the tone of each microphone or requiring down time to re-patch any cables.

  • Audition different microphones with the press of a button
  • Four selectable inputs with trim controls
  • Straight-wire distortion-free signal path
  • Saves time and improves workflow in the studio

Choose the right mic every time

The Gold Digger allows you to record with confidence knowing that you've selected the right tool for the job each and every time you record. It provides the ability to instantly A/B between up to four microphones, without introducing any coloration, noise, or distortion. Individual set & forget trim controls let you adjust each mic level so that they produce the same relative output, and 48V phantom is available to power condenser microphones. The Gold Digger makes it easy to audition multiple options while maintaining studio efficiency and ensuring a smooth workflow. When paired with the Radial Cherry Picker™ you can choose between four microphones and four preamps in any combination, giving you the freedom to explore endless sonic possibilities.

Gold Digger Applications

Comparing Four Studio Condenser Mics

The Gold Digger lets you quickly compare the sound of four microphones and send the signal to the same preamp. This assures an 'honest' comparison as all mic signals employ the same audio path. Separate 48V on-off switches let you activate phantom as needed.

Comparing Various Direct Boxes

Comparing DI boxes can often lead to surprising results. Often, one will use an active DI like the J48 only to find that a passive one like the JDI could in some instances sound better. Plug in the four DIs just like you would a microphone and you are set to go.

Selecting a wireless system

The Gold Digger can also be used in live touring where you may want to direct as many as four different wireless systems to a single audio input channel in the PA system. This could be 4 mics in a house of worship, 4 wireless guitars, or maybe a couple of mics in a town-hall meeting.

"It was in trying to hear slight tonal differences between the exact same mic models that I really appreciated the Gold Digger's transparency, ease of use, and instant switching between channels. What a great debugging tool! This is a fantastic piece of gear for any serious engineer/producer."

By Buddy Saleman

"The Gold Digger and Cherry Picker are well built properly featured and affordable. Both get the job done as promised. Radial's Gold Digger is a very useful & alluminating tool."

By Rob Tavaglione

"They do exactly what they say on the tin and do it well. As somebody who routinely evaluates multiple microphone and preamp combos, they're an absolute godsend for me."

By Jon Thornton

"When you're comparing gear in the studio, these boxes are the answer to your prayers."

By Paul Vnuk Jr.

"I have nothing but praise for both units. They're quiet and do not add color to the signal path. Most importantly, they make the difficult task of performing direct evaluations among multiple microphones and mic preamps much easier, allowing for instant side-by-side comparisons, which helps you make better choices, ultimately, better sounding recordings."

By Phil O'Keefe

"The Gold Digger is well thought-out and versatile, and it's quite remarkable how useful a product like this actually is!"

By Hugh Robjohns

"If you have more than a couple mics and preamps in your collection, I cannot recommend the Gold Digger and Cherry Picker enough. These are two products that every studio should own."

By Andy Hong

"If you have a studio or setup that focuses primarily on mono vocal tracking, this is a buy that will greatly improve your workflow... The ability to quickly switch between mics, the cleanliness of the circuit and Radial's dedication to preserving the integrity of the input signal make this a great choice for any studio."

By Brandon T. Hickey

"I love the Gold Digger! There is no need for re-patching or phantom power management when auditioning microphones. We can now change mics as fast as the artist can step up to the mic, all while retaining the same processing chain!"

George Seara

Rihanna, Drake, Holly Cole, Sting, and Herbie Hancock. 2012 Juno Award for Recording Engineer of the Year

"The Gold Digger is a must-have when I'm shooting out vocal mics. Not only does it allow quick and seamless level-matched A/Bing, but it's entirely invisible and does not alter the sound in any way."

Sebastien Lefebvre

Guitarist, Producer - Simple Plan

"The Gold Digger and Cherry Picker are 'real' toys for the studio. They let you try out every combination of microphone and preamp chain before settling on the one that best suits a particular vocal or instrument. No more having to plug and unplug your whole rig. Saves time, and really fun."
