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!
  • Warranty is transferable if the item is re-sold
  • Loan or replacement equipment will be provided if the product isn't repaired within 30 days
  • If an item can not be repaired, a similar alternative product or cash discount (as defined in this policy) will be offered
  • 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.

"The Radial Switchbone sounds great! It is the best ABY box that I have used and the transformer isolation makes it easy to combine any two amps without noise." - Allan Holdsworth

Superior Audio Quality with Class-A Circuitry and Mid Boost

The Tonebone Switchbone features the same 100 discrete class-A buffering circuit as the critically acclaimed Radial JD7 Injector for an unparalleled sonic performance. Its top panel holds three footswitches:

  • Switch 1 selects between amps A or B
  • Switch 2 allows the combination of both amps
  • Switch 3 is a built-in power booster
The power booster has a variable level control, and a 3-position mid boost switch to give you that razor-sharp edge you need when soloing. The boost can also be bypassed and converted to a mute switch for quiet on-stage tuning between songs. The Switchbone ABY's photocells ensure perfect noise free switching, even between high gain amplifiers, its second output is 100 isolated to eliminate all signs of hum and buzz, and you'll always be able to keep both amps in phase by toggling the easy access 180° polarity reverse switch.

Augmented with Drag™ Control Load Correction

The Tonebone Switchbone ABY features Radial's Drag™ control load correction, so your pickups always detect the correct impedance load, just as if it were plugged directly into an amp. This means your guitar will always produce its rich, harmonic tone and no unwanted frequencies will be emphasized no matter what it's plugged in to next. It also allows longer cable runs of up to 15m (50') without noise.

Stage Ready and Rock Solid Durability

The Switchbone is constructed from 14 gauge steel along with the entirety of the Tonebone range, meaning you can silently switch between amps gig after gig with no damage or loss of quality. Its smart flashing LEDs mean you stay in control, letting you know which amp was selected last, and along with the option of silent tuning, makes the Switchbone the ideal selector to accompany you on the stage.
