VCA and digital circuits are not acceptable as the mess with the tone of the instrument. We use photocells on the hi-impedance circuits to eliminate all switching noise and relays on the speaker level signals where high voltage is present.

Q: I have heard that using a delay with a head switcher can cause a problem with the amps. Is this true?
  
A: It depends on where the delay is positioned. If the delay is placed before the Headbone, there is no problem. If the delay device is placed after the Headbone or in an amplifier's on board effect loop, you can have a problem because the echo or reverb device will continue to generate a signal and send it through the amp with no speaker connected. It is generally not good to run a tube amp this way as the output transformer can heat up and ultimately short out. The Headbone turns on and off both the input going to the amp and the output going to the speaker – but if the delay is placed anywhere after the Headbone, it no longer control the signal. Thus, always put delay devices in the signal chain before the Headbone.

Q: Can I use the Headbone like an AB box?
  
A: It certainly could be done, but you may encounter ground loop problems as the Headbone is not set-up for this function. The Switchbone would definitely be a better choice.

Q: I have a solid-state amp and a tube amp and want to switch between them. What should I use?

A: The Radial Switchbone is an ABY box that is designed to toggle between two amps. Although not quite the same as switching heads, the Switchbone works very well, sounds amazing and will do the job.

Q: Can I use the Headbone with a MIDI switcher?

A: Yes. Most MIDI switchers are equipped with a contact closure output jack. This would be connected to the Headbone’s Slingshot input remotely control.

Q: If I do not want to use the Slingshot remote, how far from the amps and speaker can I be?

A: As a rule, the further away from your amp you are, the larger the speaker cable you will need. As a general rule, we do not recommend running cables any more than 20 feet as you are also subjecting the input cables to more noise caused by interference. If you are intent on doing so, use 14 gauge speaker cable.

Q: What happens if I use another supply instead of the 15VDC one that comes with the Headbone?

A: Never use an alternate power supply except one that exactly matches the same voltage, current and polarity as the one that comes with your Headbone. The Headbone is designed to work with this specific power and changing this could cause system failure, which of course would not be covered under the warranty.

Q: I have a 200W amp. Can I still use the Headbone?

A: yes, but you have to be careful. The impedance of your amp will actually determine the current capacity that can drive through the Headbone. Go to Maximum Power Ratings for more details.

Q: If I have a 300 Watt amp, can I modify the Headbone?
 
A: Yes. In fact we have included a provision in the design to allow a 350 Watt relay to be factory installed in the Headbone. Contact you Tonebone dealer for details on how you can order this special high power version.

Q: What if I have two amp heads; one tube head and one solid state; do I use the VT or the SS?

A: The Headbone TS allows for one tube and one solid-state amp.

Q: Is it possible to run an overdrive pedal to just one of the amps
with a Headbone switcher? (i.e. overdrive pedal after the Headbone)?

A: Yes. The Headbone signal path is as follows: guitar signal goes into
Headbone, from the Headbone you would insert a pedal, then into amp-1. The Headbone would also feed amp-2. Then the signal would come back from both speaker outputs from the two heads, back into the Headbone and then to the speaker.
