  • AB-Y switcher – Class-A for exceptional audio
  • Noiseless photocell switching between amplifiers
  • Exclusive Drag™ control pickup load correction
  • Built-in Power Boost circuit with mid control
  • Transformer isolated to eliminate ground loops

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.

 

The Switchbone's powerful features are logically laid out and intuitive to use. Setting up is easy – the two Switchbone amplifier outputs, Out-1 and Out-2, connect directly to each amp’s instrument inputs: Out-1 is direct coupled and Out-2 is transformer isolated. Use the isolated output if you have an old amp with no ground lug on its AC cord. The Switchbone's ground lift switch can come in handy to eliminate hum or buzz that may be present due to a ground differential between the two amps.

Connecting the Switchbone's power adapter turns the unit on. Plug in your guitar and you are ready to go. The LED indicators will show you the currently selected output(s). The TOGGLE footswitch switches between them. The BOTH footswitch selects both outputs, and the flashing LED shows which output will still be on when you hit the BOTH switch again. Simple and effective.
