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.
