True to the Music

Congratulations on your purchase of a Radial Headbone!

As part of the growing family of Tonebone products, the Headbone VT 

provides the discerning guitarist with options to achieve creative new 

sounds with a simple, yet extremely versatile interface. 

The Headbone VT is designed to connect two tube amplifier heads to one 

speaker cabinet and switch between amplifiers with either the on-board 

or remote footswitch. The Headbone uses pure Class-A electronics under 

digital control to switch the hi-impedance guitar signals and speaker-

level outputs from your amps. Add Slingshot™ remote control and you 

get a true marvel whose time has come! Best of all, the Headbone is 

engineered to ensure the safe operation of your amps under demanding 

live performance conditions. 

To take advantage of the wonderful features that have been incorporated 

into the Headbone, please take the time to read through this manual 

before you use it. This will give you a broader sense of the Headbone’s 

capabilities and ensure its safe and proper operation. If you have 

questions that are not covered here, please visit the FAQ section on our 

web site. This is where we post answers from questions that come from 

users. If you have a question that is not covered there, please feel free 

to send us an email at [email protected] and we will do our very best 

to respond as quickly as possible.
