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 Tonebone Plexitube is the most versatile distortion pedal I own. It's also the quietest I've ever used. I find all Radial products to be designed with sound quality, easy operation and durability in mind." - Daryl Stuermer (Genesis, Phil Collins)

Designed for Ultimate On-Stage Functionallity

The Tonebone Plexitube's two distortion channels mean switching between rhythm and lead settings whilst performing couldn't be easier. Channel-1's scooped out mids provide the perfect thick tone for your chunky, gut-shaking rhythm riffs, and Channel-2 is optimised to offer all the face-melting, sustained mids you need to cut through with razor sharp-solos. These are both augmented with individual contour controls and voicing, allowing you the customisation to dial each tone to your preference. Also ultra-bright LEDs mean you'll never be in the dark about your distortion, even on the darkest of stages!

True-Bypass Connectivity

When the Plexitube 12AX7 isn't in use, its true-bypass connections ensure your guitar's original sound reaches the amp suffering no tone sucking on the way through. Photocell switching means activating the pedal is always smooth, clean and pop-free, even with high gain amps. The Plexitube even features an integrated effects loop on the lead channel, which can automatically switch other pedals such as delay on and off for you when swapping channels, saving you the frantic foot stomping!
