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
One year parts and labor warranty. (Self-installation voids warranty.)

By Ken Wilson

from Harrogate, TN

I have to say that playing on a mic is my first choice for mandolin to get the most authentic, acoustic sound, but in the situations that I play in, playing that way is not usually and option. My mandolin almost always gets lost in the mix because I can never get my mic loud enough without feedback. I have had some luck by not putting my mando in the monitors, but obviously, that is no fun. Enter the Radius!!! I bought it, apprehensively, because it is a "non-returnable" item. The price was reasonable enough to take a chance. I had read some mixed reviews, and had talked to a couple people that I trust, and thought I had enough info to pull the trigger on the purchase. I ordered online, got the pickup in, installed it myself with great ease, plugged it in to my own pa thru an old LR Baggs pre-amp that I have had since '89. It worked surprisingly well!! What surprised me most was the tone. It has a little weirdness to me since I had only played on mics til then. So, my first gig arrives!! (My group has a couple guitar players, a fiddle, and my mandolin...the style of music is very ecclectic...def not a "bluegrass" group) I am all set to have my REVENGE!! I will finally be in the mix!! 0oops! Now the fear sets in!! I can't hide my less than perfect playing behind a mic that isn't really loud enough! Oh well, I carry on!! During sound check with the house pa and sound tech, I am poised to enjoy this experience when I realize that I have, in my excitement to get to the gig and in my hast to have some "revenge," I had forgotten my pre-amp at home! I ended up not using my mandolin at all that night...I just defaulted to my trusty guitar. I was disappointed, but still hopeful! The next gig rolls around! I am a little paranoid by this time, because, again, I am not using my own pa. It is a different venue, so the anxiety builds. I get there, help with the load in, plug in the pre-amp, plug in the mandolin, sound check....BOOYEAH!! I am good to go!! I had more fun playing music that night than I had in a very long time!! I finally had my revenge!!! I can be the peaceful person that I normally am now!! LOL!! The pickup did a great job for me and my particular situation. I am very pleased with this pickup! I haven't played anything else to compare it to, but at this point, I am not in the market to try other things. The Radius is performing very well for me! The tone is quite pleasing and surprisingly natural and good all around. I cannot stress this enough, YOU WILL NEED SOME TYPE OF PRE-AMP with this pickup. I tried a plain old, dry direct box, and it just does not work well at all!!! The preamp I have uses a 9v battery. You WILL need something to boost the signal BEFORE it gets to your mixing board, since the pickup is PASSIVE. The preamp essentially makes your pickup "active" and is, thusly, "hot" enough now. The radius was a great choice for me, because I already had a couple of pre's that I thought could work. The pickup is cheap enough, and since you can install it yourself (another money saver), you can maybe afford a good pre-amp too. Again, my guess is that you WILL need one, otherwise, my "2 cents" is, you might as well be playing on a mic.

The pickup is great but I didn't buy it from Guitar Center

By Steve Schneider

from Nashville, TN

I tried to buy the pickup from Guitar Center doing a ship to store. I needed it for a new mandolin and figured ship to store would be faster than shipping it to the house. Man, was I ever wrong. I kept calling and bugging the store but it never came. I finally cancelled the order and bought it somewhere else. Amazingly enough, a few day's after I bought the pickup from a different store, Guitar Center called me and said they were going to ship the pickup back if I didn't come pick it up. I told the guy the that called the story and had a good laugh. I checked my bank account and they had already refunded the money so it's all good but I'm never doing a ship to store again. If I buy something from GC it will be because I saw it in the store.

Well, i went to my local Guitar Center looking for some way to amplify my ukulele. they had nothing in stock but suggested this to me. due to me being desperate, i bought it and I'm very pleased. it has a pretty nice sound and all but it obviously wasn't made for a ukulele. 5 stars cause its better than most and at least I'm amplified now. definatly go buy it.
