My Personal Recommendations for a Ukulele DI



The Fire-Eye Red-Eye, the Radial JDI or J48 are the two pedals that I go to for the ukulele live. Get the Jenson equipped Radial.
2019 Update: The LR Baggs Align Series Active DI is promising. I have the Reverb, Chorus and Equalizer pedals for my ukulele.


Been using the Fire-Eye, Red-Eye exclusively with my ukuleles. Simplest the best and easiest to use DI I've ran across. Going to get a few more of these for our Funky Frets store main stage.
I love this Red-Eye for is lack of additional knobs and controls - less to mess up. And, for the boost part for taking solos at loud jams with a full band - guitar and all can drown out the ukulele.
Checkout these for some great info on sorting out just what a DI - active or passive - does.

Radial is one of the go to source for seasoned sound engineers. Really great gear. I have a couple that I use on the main Funky Frets stage.

Fire-Eye Red-Eye Instrument DI w/Boost
The Red-Eye is an all analog, handmade, high input impedance DI and clean boost. Designed and improved over the course of several years to meet the needs of performing musicians, the Red-Eye is crafted from the highest quality components available. Engineered by an electronics engineer with over 50 years of professional experience, the Red-Eye design focuses on high fidelity, low noise and simple plug and play performance. This no frills precision approach to amplification offers a truly satisfying experience for musicians and their audience.

Radial Engineering R8001010JDI Single-Channel Passive Direct Box with Jensen Transformer
The JDI is a high performance passive direct box for live concert touring and professional studio recording applications, featuring a premium Jensen transformer for exceptional audio performance.
The Radial JDI is a passive direct box designed to handle extreme signal levels without distortion of any kind. At the heart, the Radial JDI employs the world class Jensen JT-DB-EPC audio transformer delivering a smooth, warm sounding Bessel curve, reminiscent of the finest vintage gear. Ruler flat from 10Hz to 40kHz and with virtually zero phase deviation, the JDI delivers the natural, pure sound of the instrument without artifact. By its no-power passive design, the Radial JDI performs both high-to-low impedance conversion and signal balancing over a magnetic bridge that passes signal while rejecting stray DC voltage. This makes the JDI particularly adept at eliminating hum and buzz caused by ground loops.

LR Baggs Venue DI Acoustic Guitar Effect Pedal
Every Tool You Need in One Acoustic Pedal.
The Venue DI gives you complete control by combining a full-isolation DI output, 5-band EQ with adjustable low & hi-mid bands, variable clean boost, and chromatic tuner all in one acoustic pedal.

LR Baggs Para Acoustic D.I.
Studio quality performance, powerful tone shaping EQ and rock-solid reliability, the Para DI has become an indispensable stage tool for countless musicians around the world. This roadworthy box effortlessly tames the stage and enhances any acoustic pickup for a fuller, more complex sound.

We started this in a loft in downtown Los Angeles, California, with a hope and a dream, and no business sense whatsoever. The first L.R. Baggs product was our LB6 Series Pickup. We would like to thank Leo Kottke for his early support. Stores would call us and say, "Leo Kottke said he was using your pickup." We could literally track his touring route as the stores would order in his wake. Early endorsers were Steven Sheehan of the Judds, James Taylor and Kathy Mattea. These endorsers gave us the encouragement and support that sustained us when we had more enthusiasm than business sense. They spread the word and gradually our business grew.
