NOT A SHRED OF NOISE

This latest Stagebug from Radial Engineering might interest guitar players and studio owners alike. The SB-15 Tailbone is designed to sit at the beginning of the guitar-to-amp signal chain and drive multiple pedals to get rid of the noise that often plagues high impedance circuits – no, not any Stairway To Heaven riffs. The Tailbone has a standard hi-Z instrument input feeding the signal through Radial’s Dragster load correction circuit to replicate the tone and feel as if connected directly to the amplifier. It’s then buffered via a 100% discrete, class-A unity gain amplifier. Unlike most similar devices that employ ICs or integrated circuits to buffer the signal, the discrete design reduces the need for phase-cancelling negative feedback producing a more natural tone. Once buffered, the SB-15 Tailbone lowers the impedance and susceptibility to hum and buzz caused by radio interference and electromagnetic fields. The SB-15 Tailbone is able to drive multiple pedals distances of 15 meters without noise. It also provides an alternative power solution for Radials Tonebone pedals, which need 15 volts and don’t sit well with global 9V power supply bricks. The Tailbone can take two standard nine volt feeds and output the 15 volts required. Full specs at www.radialeng.com
