Radial Engineering SB-15 Tailbone - Combination buffer and 2x9V to 15V converter for Tonebones

SB-15 Tailbone - a high performance signal buffer designed to sit at the beginning of the signal chain and drive multiple pedals without the added noise that often plagues high impedance circuits.  
 As an extra bonus, you can combine two 9V outputs from your power brick and the Tailbone will convert them to 15VDC for Tonebone pedals.
