Sold out.

The Radial Headbone is an advanced 'head switching device' that allows two different guitar amplifier heads to be used with a single speaker cabinet. With Headbone, one head could be used for rhythm while a second head could be used for soloing. With 100% discreet class-A circuitry and choice of either buffered or un-buffered inputs, the Headbone will be of particular interest for players that demand the utmost in tonal performance.

The Headbone's internal switching comprises a sequence of relays, photocells, and load resistors, all of which are controlled via a digitally programmed chip. Hit the footswitch and the Headbone toggles the guitar signal from one amp to the other, disconnects the speaker and diverts the signal to a load resister, reconnects the speaker to the second head and turns on the guitar, all in quick succession. The Headbone features SafeModeT whereby even when power is disconnected; the Headbone will automatically default to a 'head-1 to cabinet' status, ensuring a constant load on the amplifier.

To eliminate running guitar and speaker cables to-and-from the amplifier and the pedal board, the Headbone is equipped with SlingshotT, an easy to use remote control system that employs a standard foot switch to toggle the Headbone's status from a remote pedal board.

The Headbone is available in 3 models: The VT for two valve-tube heads; the SS for two solid-state heads; and the TS for Tube to solid state switching. Headbone. another Radial 'power tool' for serious guitarists.

Headbone Setup:
Plug your guitar or FX chain into the Headbone's 'DIRECT' or 'BUFFERED' input*. Connect 'To AMP-1' to one amp head and 'To AMP-2 to the the other using standard 1/4" guitar cables. Connect the speaker outputs from each amp to their respective 'FROM AMP-1' and 'FROM AMP-2' 1/4" jacks using high grade speaker cables*. Now just hook up a speaker cable from the 'To Speaker Cabinet' jack to your speaker(s), and that's it...

But wait... there's more! Headbone is equipped with Radial's Slingshot™ remote switching. Slingshot lets you
keep the cables between amps, cabinet and Headbone all short and neat. All you have to do is plug a standard footswitch into the Headbone's 'Slingshot™ Remote' input* and change amps from wherever you want to put the switch!
