StageBug SB-15 Signal Buffer
Signal Buffer & 9V to 15V converter
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. It also converts two 9V power outputs to a 15V supply as an alternative way to power Radial and Tonebone 15V products.
100% discrete class-A signal buffer
Drag control load correction for natural tone
Drives pedal chains up to 15 meters (50ft)
Converts two 9V supplies to 15V output
Drive pedal chains with ease
The SB-15 is an ultra-compact signal buffer that is pedalboard friendly, with transparent operation that maintains the natural tone of your instrument. Unlike many audio designs that employ ICs or integrated circuits to buffer the signal, the 100% discrete class-A design of the SB-15 reduces the need for phase-cancelling negative feedback produces 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 meters (50') without noise.
Power 15V Radial and Tonebone Pedals
The SB-15 Tailbone is powered by a standard 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 SB-15 will convert them to 15VDC and provide the correct voltage polarity. This makes adding a high-end Tonebone or Radial device to your pedalboard easy.
SB-15 Specifications
The Radial StageBug SB-15 is a combination hi-Z signal buffer and DC power adaptor for pedalboards. It features a 100% discrete class-A signal path for optimal signal transfer and is augmented with Drag Control load correction to match the source pickup with the pedal chain. Once connected, the SB-15 lowers the impedance and susceptibility to noise, enabling longer cable runs without noise. For Tonebone users that require a 15DVC supply, the SB-15 incorporates a DC to DC converter that converts two 9V supply lines from a typical power brick to 15 volts.
