Two Tube Heads, One Cab, No Hassles

The Radial Headbone is a power tool for serious guitarists (at Sweetwater, we've got plenty of those)! Headbone is a purpose-built switching device that lets you toggle between two different tube amp heads while using a single speaker cab. With a Headbone in your rig, you can deploy, for instance, your Marshall head for rhythm and your Mesa-Boogie for solos. The Headbone rocks 100% discrete Class A circuitry for phenomenal audio performance, a transformer-isolated signal path to eliminate ground loops, and your choice of buffered or un-buffered inputs to optimize the signal path. If you demand maximum tonal perfection onstage and in the studio, the Radial Headbone is a must-have.

Radial Headbone VT Tube Amp Head Switcher at a Glance:
  • Works like magic (but it's not)
  • Peace-of-mind and convenience
Works like magic (but it's not)

Being a Radial product, Headbone does its job flawlessly, gig after gig. Seems like magic, but what's under the hood is simply solid engineering. Headbone's internal switching consists of a series of relays, opto-couplers and load resistors, all sequenced via a digitally programmed chip. When you hit the footswitch, Headbone cleanly toggles your guitar signal from one amp to the other, disconnecting the speaker and diverting the signal to a load resister, before reconnecting the speaker to the second head and turning your guitar signal back on - all in an instant.

Peace-of-mind and convenience

During a gig, you've got plenty to think about. That's why Headbone features Radial's proprietary SafeMode, which automatically switches off your guitar input in the event of a power interruption. And to eliminate messy spaghetti cables onstage, the Headbone is equipped with Slingshot, a remote control port that lets you switch the Headbone using a standard (optional) footswitch or MIDI-controlled contact closure - thus eliminating long speaker cables and improving system efficiency.

A great, compact amp switching solution.

A nice little unit—compact and easy to use. Our YouTube channel was recently sent one of these to demo. Below is a video on how I incorporated the Headbone VT into my studio rig. It also covers how to properly connect it up (and a few additional things you should consider before buying). Feel free to check it out via the link below. Thanks!

Couldn’t Be Happier!

The setup is straightforward and logical. Works EXACTLY as advertised. Built like a tank. This is my second Radial product. They build good stuff.

Pro tip... get the Radial latching footswitch and run this box remotely. Trying to use this in a pedalboard setup would be a huge mess. Running it by the remote switch is the way to go. The footswitch is the Radial Engineering JR-1L Latching Footswitch with Active (LED) Or Passive Circuit Selector... Trust me on this, it's worth it. It fits easily in a pedalboard.

Does the job well

Sturdy and reliable. Adds no noise I can hear. Best to place on top of amps and use remote as slingshot.
Rated 4/5

The first head switcher that does exactly what it says.

Works perfectly. PERFECTLY. I loving having the freedom to switch between heads while on stage.

Lost a star because it's quite bulky. Gotta run 5 cables into this thing (half are speaker cables).
It says there's a slingshot that can be used but I cannot find it online anywhere.

It kind of works…

I bought this 3 months ago and I have used it extensively. It has always had a problem switching between channels. I click the remote switch and it illuminates but it does not switch to the other head. It most of the time takes multiple tries to get it to switch. Today I was messing with my rig trying to figure out why I wasn't digging my tone anymore. When I decided to bypass the inputs on the headbone. There it was my tone was back. I tested input and output cables, I tried the ground lift switch, buffered input and direct input. Nothing sounded the same as plugging straight into the amp.
