## Description

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 GearNuts, we're quite taken with Radial's little StageBug SB-2. We think you will be, too.

Review: Excelente producto - Muy buen producto
Review: Top quality - great sound - Have been using a Behringer DI a number of times recently, mainly for the monitoring of my Stagepiano and I find the sound has improved a lot since using the Radial. Given I’m also a bass player, this is the perfect DI box, as it is for Bass and Keyboards.

## Questions & Answers

**Q: can i use this as an alternative to the WALRUS CANVAS mono? Can the thru be used as a second input, summing both to the XLR out ?**
A: Yes, this sums the inputs automatically if you use the thru as an input.

**Q: Will this work with a passive bass?**
A: Yes, but I think that you would like the SB-1 Active Direct box better.  Even though it says that it's called SB-1 Acoustic, it works really well for passive bass guitars. http://www.amazon.com/Radial-Engineering-StageBug-SB-1-Acoustic/dp/B00B5LCV2I

**Q: The bass player at our church uses a amp how do I connect this to the bass and our sound system so she doesn’t have to use the amp**
A: 1/4” cord from bass/pedalboard -> DI -> XLR (mic) cable to snake. If it’s a passive bass, you might want to look into the SB-1 active instead of the SB-2 passive.
