SB-15 Specifications

The Radial StageBug SB-15 is a combination hi-Z signal buffer and DC power adaptor for pedalboards. It features a 100% discrete class-A signal path for optimal signal transfer and is augmented with Drag Control load correction to match the source pickup with the pedal chain. Once connected, the SB-15 lowers the impedance and susceptibility to noise, enabling longer cable runs without noise. For Tonebone users that require a 15DVC supply, the SB-15 incorporates a DC to DC converter that converts two 9V supply lines from a typical power brick to 15 volts.
