Banish unnecessary noise with the Radial StageBug SB-15 Tailbone, a high power, high performance signal buffer that will clean your chain right up. When placed at the beginning of a signal chain, the SB-15 will drive and buffer each pedal with its 100% discrete, Class-A circuitry. And with the Drag control, you can perform load correction functions with ease. To top it all off, the SB-15 Tailbone can drive multiple pedals at distances of up to 50' and even convert two 9V supplies from your power brick or source to 15V power.
