Radial StageBug SB-15 Tailbone, 9V to 15V Converter with Signal Buffer, Radial Item R800 0115.

The Stagebug SB-15 is a class-A signal buffer designed to sit at the beginning of the signal chain and drive multiple pedals without added noise or signal loss. The 100% discrete class-A design of the SB-15 reduces the need for phase-cancelling negative feedback, producing a more natural and pleasing tone. This is complimented by a Drag control load correction circuit to replicate the tone and feel as if connected directly to the amplifier. Once buffered, the signal is less susceptible to hum and buzz caused by radio interference and electromagnetic fields, and is then able to drive multiple pedals distances of 15 metres (50 feet) without noise. As an extra bonus, you can combine two 9V outputs from your power brick and the SB-15 will convert them to 15VDC and provide the correct voltage polarity. This makes adding a 15VDC Tonebone or Radial device to your pedalboard easy.
