Radial SB-15 Tailbone: The Ultimate Signal Buffer & Converter
• Signal Buffer & 9V to 15V Converter •
The Stagebug SB-15 is a class-A signal buffer that sits at the start of your signal chain, driving multiple pedals without noise or signal loss. It also converts two 9V power outputs to 15V, powering Radial and Tonebone 15V products.
Effortlessly Drive Pedal Chains
The ultra-compact SB-15 is pedalboard-friendly with transparent operation, preserving your instrument's natural tone. Its 100% discrete class-A design reduces the need for phase-cancelling negative feedback, delivering a more natural and pleasing tone. A Drag control load correction circuit replicates the tone and feel of direct amplifier connection. Buffered signals are less susceptible to interference, driving multiple pedals up to 15 meters (50') without noise.
Power Your 15V Radial and Tonebone Pedals
The SB-15 Tailbone runs on a standard 9V supply (not included). Combine two 9V outputs from your power brick, and the SB-15 converts them to 15VDC with the right polarity, making it easy to add high-end Tonebone or Radial devices to your pedalboard.
Use the SB-15 as a Signal Buffer
The SB-15 corrects load and reduces noise susceptibility when driving multiple pedals and a distant amp, making it the ideal front end for your pedalboard and guitar setup.
Use the SB-15 with a Power Brick
Most power bricks have only 9V outputs. The SB-15 simplifies powering your 15V Tonebone by converting two 9V outputs to the right voltage and polarity.
Use the SB-15 on Your Pedalboard
Make the SB-15 the ultimate front-end for your pedalboard. Connect it to your pedals and amp for less noise and a more natural tone.
