The Golden Bullet microphone element is no longer being produced as a regular item by K&K Sound. As such, the current stock is the last remaining stock of this item. Once sold, it will no longer be available.


K&K's various bass transducers can deliver an exceptionally warm and natural sound -- but there are times when a microphone can add extra warmth and life to your signal, or perhaps be the total true voice of your bass. Choosing and using a microphone can be a real challenge and an expensive proposition, especially when you want to blend it with your current rig. K&K Sound has taken all the hassle out of the process by creating a series of professional systems that can work for you immediately -- right out of the box.

Includes our exclusive Gollihur Music tipsheet to get the most out of your purchaseThis specialty Double Bass Microphone is available in several different configurations. You can get the mic alone (with its own phantom power/output box), you can opt for the upgrade system (has a second input to be used with your existing pickup), or you can get a combination system with the mic and one of K&K's excellent pickups, either the Golden Trinity/Bass Max or the Golden Trinity/Double Big Twin.

The Golden Bullet Microphone is a condenser mic chosen specifically for its characteristics and performance with the Double Bass. This is not an "off-the-shelf" microphone, but one designed and custom built by K&K in their shop in Oregon. I was delighted to work with Dieter of K&K to finalize the selection of this specific unit, which combines great sound with excellent feedback resistance. It's unidirectional to help avoid rumble and bleed from other instruments. Amazingly light and small, it is mounted on your bridge using adhesive 3M Dual Lock and positioned using its built-in six-inch gooseneck. And don't worry about the bridge mounting -- I stuck the mic attachment to a mail scale, and the assembly registered about .25 ounces in weight!

Please note: If you have never used a microphone with your bass before, please realize that there are limitations to microphone use - that's why transducers were developed! There is far greater feedback potential, and it will require greater care to position your bass, mic, and speakers, and adjust EQ to avoid feedback or unwanted resonances. This is why each system, excepting the Golden Bullet Mic by itself, includes the ability to combine the mic with a transducer -- so the player has the option to rely on a more feedback-resistant transducer in tight or loud stage situations where a mic alone is not practical.

SPECIFICATIONS for the Microphone:


  • Frequency Range: 20 - 17,000 Hz
  • Sensitivity: 7 mV/PA/1 kHz
  • Maximum SPL: 139 dB
  • Polar Pattern: Hyper-unidirectional
  • Output: XLR active balanced or 1/4" line level (your choice)
  • Mic Power Supply: 9 Volt through Supplied Golden Bullet preamp
    • Choose a 1/4" output or XLR output box (XLR output box can be phantom powered!)
    • You can also buy the "solo" model, which includes NO box - you will need a preamp that can supply 9v phantom power at the 1/4" input to use the SOLO mic; a good option is the LR Baggs GigPro preamp (which was discontinued at the beginning of 2022).
