Let your mandolin sing loud and clear with the Radius.

The LR Baggs Radius, a tiny wonder of a pickup, is specially developed for the mandolin, violin, and other high-voiced instruments.

At the heart of the pickup's transducer is a highly flexible beam with a .004" thin film sensor, similar to mic diaphragm material, attached to its surface. The beam is held in equilibrium and damped by opposing Neodymium magnets, another LR Baggs innovation. The sensor floats between the magnets and is not bogged down in viscous fluid or clamped between elastomeric pads, so it is completely free to respond instantly to the smallest nuance without artifact or coloration. Also, the magnets are tuned to progressively damp the sensor and respond naturally to the dynamics of the musical instrument.

The frequency response is linear, silky-smooth, and accurate with an astonishing natural and effortless sound. Unlike most soundboard transducers, the Radius pickup is also very tolerant to placement and works well in a variety of locations. The output of the device is quite strong, allowing passive use with a normal-length cord without a preamp into most acoustic amps. The case is injection-molded of a non-resonant conductive ABS material developed in collaboration with a respected plastics manufacturer. The CAD-designed case acts like a vault for the transducer, insuring ultra quiet operation.

The LR Baggs Radius pickup may be mounted to the outside surface of the instrument with a removable, non-destructive adhesive or to the inside with VHB adhesive. The Radius "kit" includes adhesive, a 1/4" stereo jack, and a side mount jack holder to enable internal or external mounting.

  • Highly flexible beam with .004" film sensor
  • Neodymium magnets
  • Mounts internally or externally

Size doesn't matter with this tiny yet mighty transducer pickup.

    Comments about LR Baggs Radius Transducer Pickup for Mandolin:

    It is the best for a mandolin, especially for when you're using on stage. It's like a mini mic in your Mandolin. I installed it inside the mandolin, and that's where the pickup does best. I have two pickups now on both of my mandolins. They sound great! And if anyone is still unsure about the mandolin pickup watch Sierra Hull on the LR Baggs Channel. She's a Profesional mandolin player and you can see how these pickups do great while she is playing along with the pickup. That's all I have to say.

    I ended up going with K&K Twin Internal

          Comments about LR Baggs Radius Transducer Pickup for Mandolin:

          I bought this mandolin pickup for my Breedlove mandolin. Here's why I gave it two stars.

          1. I attached the pickup with the putty as directed in the instructions, but the mandolin sounded like it had a phaser on it. I didn't like the sound at all.
          2. If you use it with stage monitors it has a tendency to feedback.
          3. It had a tendency to pop off during a performance.
          4. Despite being an external pickup, you're much more likely to scratch the mandolin while putting it on or taking it off.
          5. You need to use an external preamp to get it to sound decent.
          6. It's overly noisy. You hear every tap and rub on the mandolin's body.

          For the price of this pickup and LR Baggs Para Acoustic D.I. together you can buy and have an internal pickup installed by a professional tech. Not only do I think internal pickups sound better because they're mounted more solidly, but you don't have to worry about it popping off during a performance.

          Because I have a new mandolin I went with K&K Twin Internal mandolin pickup. Though I had to modify my mandolin, I'm much happier, and I don't think it's affected the value. I hear no difference in the sound quality after the K&K was installed. It doesn't have the problems that this pickup has.

          I don't want to offend anyone who likes this pickup, but as someone who has tried it and was disappointed, I just would like to save some people some time and money in the long run. Maybe you'll like this pickup.

          Very good mandolin p/u

          Comments about LR Baggs Radius Transducer Pickup for Mandolin:

          I got an Ibanez A510 for Christmas (thanks to mt loving family). I needed some way to amplify and miking was just not working. I've had success with LR Baggs products in the past so I gave this a try.I run this through my acoustic rig at church - an Ibanez compressor, Morley Chorus/Volume pedal (great product) and a Fishman DI into the board.Good: Easy installiation. Sounds pretty good (hence the 4.0). Gets me away from miking.Not so good: Really needs to be run through a DI as straight into the board sounds harsh (I've got the same problem with my Martin with Fishman electonics).Wish it had: A volume control. I do have a volume pedal but a volume on this would be great.
