Tiny Passive DI. Big Performance.

Radial's high-performance StageBug SB-2 passive DI delivers warm, vintage-flavored direct sound from your bass, keyboard, or acoustic guitar. The StageBug SB-2 is equipped with a custom Eclipse ET-DB3 transformer that impedance-matches and balances your signal, and also helps eliminate buzz and hum due to ground loops. This ultra-compact direct box handles high input levels with natural compression, and it's also equipped with a 15dB pad for extra-hot signals from active bass pickups, digital pianos, and the like. The StageBug SB-2 is a mono device; input a stereo signal on TRS, and the unit's convenient stereo-to-mono merge function saves you from having to reset your source to mono. At Sweetwater, we're quite taken with Radial's little StageBug SB-2. We think you will be, too.

  • Passive mono DI for bass, keyboards, and acoustic guitar
  • Smooths out peaks and warms up your tone
  • Ultra-compact, fits in your gig bag
  • Easy-to-use, plug-and-play feature set

Great Radial Product

A great sounding DI. Simple, small with no sacrifices with sound quality. Every musician & audio engineer should have at least one of these in there working tool box &/or microphone case. While I have a variety of Radial products, this is my go to DI.
Music background: Many years of Audio & Tenor Sax


I use this for multiple applications. Firstly, on bass guitar I use this to send my pedal board's DI signal to my XR18 mixer and in ear monitors. Secondly, the thru output can be used to send to a separate recording interface or amp and cabinet. Thirdly, on keyboards, you can use the mono sum feature to sum a stereo keyboard signal into mono with absolutely no noise! I love my Stagebug SB-2. For a Radial DI BOX, this is the best value, period.
