The ultimate AB-Y guitar amp switcher! Switchbone is a creative tool that is designed to allow your guitar to drive and control two amplifiers without introducing noise, distortion, clicks or pops. Most importantly, the Switchbone will retain the natural sound and feel of your instrument.

The Switchbone employs the same Class-A circuit as the critically acclaimed Radial JD7 Injector for exceptional audio performance. Our unique Drag™ control provides single-knob load correction to re-introduce the natural relationship between the amp and guitar pickup that is invariably lost when the guitar is buffered or split to drive two amps. To eliminate hum and buzz caused by ground loops, the Switchbone’s second output is transformer equipped for 100% isolation. A 180º polarity reverse switch keeps both amps in phase.

Radial's acclaimed VariBoost™ power booster gives you complete foot-switchable control over boost gain and mid boost for soloing. The innovative ‘ToggleMode™’ footswitch with large flashing LED's simplifies switching and eliminates tap dancing. The tuner output is always on for quick tune-ups and buffered to keep your signal path clean.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
