Stage Bug SB-1 has the same design and function attitude as the rest of the Radial Stage Bug range - including the essential (non-negotiable) elements for a squeaky clean signal path, and gets it all crammed into a super-compact housing, so there's no excuse for traveling to a gig without one.

Small enough to stick in an acoustic guitar case or the string pocket of a guitar bag, SB-1 is an active DI (requires 48v phantom) to help balance and drive your guitar output safely to the PA system.

Input is via a standard ¼" jack, with a thru-put to feed your tuner or your on-stage amp. The active circuit converts your signal from high to low impedance to reduce susceptibility to noise, buffers it and then balances the signal for long runs to the PA system.

Inside the stiletto-proof 16 guage steel case is a carefully selected 220k-ohm input impedance to eliminate problems with loading while delivering a smooth, warm sound to the audio system. This is particularly important when interfacing vintage guitars with low output pickups when should you plan to do some recording or Reamping.

SB-1 is also includes a switchable -15dB pad that reduces the input sensitivity to gracefully handle even the loudest instruments. This makes SB-1 perfectly well suited for electric bass and keyboards. To reduce feedback, toggling the 180° polarity switch helps eliminate hot spots on stage that can cause low frequency resonance.
