Description
Anyone who’s played a big room with mixed-up grounding knows the sound: that low, ugly hum sitting under your low B. The Radial StageBug SB-6 is built to make that noise disappear, cleanly and passively, so your tone stays yours.
- Handles both balanced and unbalanced signals through 1/4″ TRS inputs and outputs, so mono and TRS connectors both work
- Automatically senses and converts hi-Z to lo-Z or lo-Z to hi-Z depending on what you plug in — no switches to think about mid-set
- Two ultra-linear Eclipse transformers keep the frequency response flat from 20Hz to 20kHz, so your low end and top-end attack come through untouched
- -10dB input pad on board for taming hot sources
- Polarity reverse switch on output B for keeping stereo rigs phase-aligned
- Fully passive design — no power supply, no batteries, just plug in and go
- 16-gauge steel chassis with durable powder coat finish, built in Canada for stage and studio duty
For bass players running stereo rigs, dual amp setups, or pedalboards feeding multiple destinations, the SB-6 is a simple fix for a common headache. Two channels of isolation in one box means you’re not stacking multiple DI boxes just to keep things quiet. It’s the kind of unglamorous gear that earns its spot on the board because it just works — night after night, load-in after load-in.
Whether you’re isolating a stereo guitar rig, cleaning up a two-channel line-level path, or just trying to get through a gig without a ground loop hum ruining a quiet passage, the SB-6 handles it without adding coloration or hassle.
