Headbone User Guide

INTRODUCTION

Attempting to use a solid-state amp with the Headbone VT 

could damage your amp and/or the Headbone. This would 

void your warranty. Please consult your dealer and make sure 

you fully understand the ownership disclaimer on the inside 

cover of this manual before using the Headbone. 

When developing the Headbone, we asked guitarists: 

“What would be 

the ultimate guitar setup?”

  Ask 10 guitarists this question and you will 

likely get 10 different answers. The reason for this is simple: There are 

no right answers as the possibilities are endless. So where do you start? 

You need a concept. The following is a setup concept that will help get 

those creative juices flowing. It combines simplicity with awesome stage 

performance. 

In the example below, amp head-1 is a 100-Watt 2-channel amp with one 

channel set to clean and the other set to saturated distortion. Amp head-2 

is a low power 30-Watt amp that would be driven ‘hard’ for natural power-

tube overdrive. Inbetween the amps and a single speaker cabinet sits the 

Headbone allowing you to select between amps with a remote footswitch 

on your pedalboard. Add a good distortion pedal, like a Tonebone Classic 

tube distortion, and your setup becomes a tone monster.
