The product price includes a one year warranty and 30 day money back guarantee.

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.

Radial Bones Twin-City ABY Amp Switcher


The Radial Bones Twin-City is an active ABY switcher and buffer that enables you to connect any two amps and drive them simultaneously without noise, loss of gain and without degrading your natural guitar tone. This is accomplished with Radial's highly acclaimed buffering technology and the same Drag Control (TM) load correction circuitry as used in the award-winning Radial JD7 Injector. The 'set and' forget Drag Control lets you compensate for cable signal loss and introduce the perfect amount of loading to replicate the way your guitar and amp interact.

  • Comments from customers who bought this item:

  • Buffered ABY with Drag load correction
  • Isolated output eliminates hum and buzz
  • 180º polarity sets both amps in phase
  • Compact to fit on any pedalboard
  • Standard 9 volt power supply operation

To eliminate hum and buzz from ground loops, the Twin-City is equipped with an isolation transformer on output B. This is augmented with a ground lift switch and 180º polarity reverse switch that ensures both amplifiers play in phase while noise is reduced to an absolute minimum even when using older vintage amps that are generally more prone to noise. As a buffer, the Twin-City lowers the impedance and susceptibility to noise, making it the ideal signal driver for large stages when using long cable runs.

Like all Radial products, the Bones are constructed from heavy 14 gauge steel for greater durability and added 'stay put' when kicked around on a busy stage. For even greater durability, the Twin-City employs our latest EIS - Electronic Impulse Switching - for unmatched performance without the challenges posed by mechanical switches. Bright, easy to see LEDs deliver on-stage switching cues so you know exactly where you are at all times.

As most players employ pedalboards, the Twin-City features standard 'Boss style' 9V powering that will adapt to most multi-pedal power supplies. The ultra compact design with top mounted output and DC connections allow pedals to be placed close together for those wishing maximum pedalboard density.

The Twin-City is a powerful ABY switcher that delivers all of the natural tone, punch and clarity of a true-bypass device without the popping noise of mechanical switches or the induced hum and buzz caused by ground loops.
