The Radial SB-15 Tailbone is 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.

The ultra-compact design begins with a standard Hi-Z instrument input.  The signal is then 'tamed' using Radial's unique Dragster™ load correction circuit to replicate the tone and feel as if connected directly to the amplifier.  The signal is then buffered via a 100% discrete, class-A unity gain amplifier.  Unlike most others 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 and pleasing tone.  This is further advanced with the same award winning class-A buffer that is in the Radial JD7 and used by guitarists as diverse as Steve Vai, John Petrucci, Steve Lukather and many others.  Once buffered, the Tailbone lowers the impedance and susceptibility to hum and buzz caused by radio interference and electromagnetic fields.  The SB-15 is then able to drive multiple pedals distances of 15 meters (50') without noise.

The SB-15 Tailbone is powered by a standard Boss-style 9V supply (not included).  As an extra bonus, when using a Tonebone pedal that requires 15V on your pedalboard, you can combine two 9V outputs from your power brick and the Tailbone will convert them to 15VDC and provide the correct voltage polarity.  This makes adding a high-end Tonebone to your pedalboard easy.

The Radial SB-15 Tailbone delivers exceptional sonic quality, reduces noise and adds the convenience of 15VDC power for your Tonebone.

Radial Engineering StageBug SB-15 Tailbone Applications:

  • Using the SB-15 as a signal buffer - The SB-15 correctsthe load and lowers susceptibility to noise when driving multiple pedals and adistant amp.  This makes theSB-15 an ideal front end for your pedalboardand guitar setup.
  • Using the SB-15 with a power brick - Most power bricksonly have 9 volt outputs.  TheSB-15 makes it easy to power your 15 voltTonebone by using two 9V outputs.  The SB-15 converts the voltage andpolarity to suit.
  • Using the SB-15 on your pedalboard - Use the SB-15 as theultimate front-end for your pedalboard.  Connect the SB-15 to your pedalsand amp for less noise and a more natural tone.

Radial Engineering StageBug SB-15 Tailbone Features:

  • 100% discrete Class-A buffer
  • Drag™ control load correction
  • Drives pedals to 15 meters (50 ft)
  • Converts two 9V supplies to 15 VDC
