However, the Gear4music extended warranty scheme provides an enhanced service, and is designed to offer a higher level of protection than many 'free' warranties offered by some retailers and manufacturers.

The highlights of this enhanced warranty service are:

  • Warranty is extended to 5 years from the date of delivery.
  • Our Money Back guarantee is extended from 30 days to 90 days (terms apply after 30 days)
  • Collection and delivery costs are included for the first two years
  • Claim 50% cash back on the cost of the policy after 5 years if it has not been used!

  • The policy can be cancelled within 30 days, and at any time after that for a pro-rata discount

Please note that this extended warranty is currently only available on products sold within the EU or EEA, and is subject to the terms and conditions as detailed on the extended warranty certificate provided.

For customers in outlying areas of the country, the price of the Extended Warranty may be marginally higher, due to the potential for higher collection and redelivery transport costs.

This enhanced warranty is in addition to the standard Gear4music and manufacturer warranty policies, and the Gear4music terms and conditions of trade. No statement or condition of sale contained within these terms affects or restricts your statutory rights as defined under the Consumer Contracts Regulation 2014.

"For years I've been trying to combine all of my favourite tones on stage without carrying around a ton of amps and cabinets on stage. The Headbone helps me get there. Thank God I found it. I only wish I had it years ago... I love my Headbone!" - Mark Tremonti (Creed, Alter Bridge)

Premium Tube Amp Head Switcher with Class-A Circuitry

The Headbone VT solves so many problems the serious guitarist has faced for years; 'how can I use my favourite amp heads conveniently without having to lug around a speaker cabinet for each one?' Complicated signal paths and an unruly webs of cables are a thing of the past. Now you can plug your instrument, amp heads and one speaker cab into the single handy unit that gives you the ability to use your Marshall head for rhythm and your Mesa-Boogie head for soloing, with switching only a foot stomp away! Featuring 100 discrete class-A circuitry for unparalleled audio performance, transformer isolated guitar signal paths to eliminate ground loops, plus a choice of either buffered or un-buffered inputs to optimize the signal path. The Tonebone Headbone's internal switching comprises a series of relays, opto-couplers and load resistors, which are all sequenced by a digitally programmed chip. Hit the footswitch and the Headbone jumps into action as it 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 the guitar back on - all in milliseconds that you won't even notice!

Safemode™ and Slingshot™

Radial's Safemode™ features in the Headbone so if the worst happens and power is lost, it's not a problem, the guitar input will automatically switch off and your amps stay safe.To connect the Headbone, you will only need three guitar cables and three speaker cables, all of which can be hidden behind the amp out of view. The mess of leads you're used to will disappear with the Slingshot™ feature; it allows remote operation of the unit with any standard footswitch or MIDI controlled contact closure. This simultaneously reduces long speaker cables and increases system efficiency, you'll have a serious sonic 'power tool' at your feet!

VT is One of Three Headbone Models

The Headbone is available in 3 models: The featured Headbone VT is for two valve/tube amplifier heads, the SS is for two solid-state heads and the 'hybrid' TS is for tube to solid-state amp head switching. Make sure you choose the right one!
