All Products are new unless stated, and include a minimum of one year warranty.

(Includes 90 day money back guarantee)


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.

Roland S4000M REAC Merge Unit


The Roland S-4000M Merge Unit combines up to four Digital Snakes to be merged into a single REAC device. This function is ideal for venues that are equipped with Roland’s V-Mixing systems or other snake devices. The S-4000M can be used to distribute a number of REAC devices’ inputs and outputs around a stage in a more organised, flexible setup. This allows you to connect more inputs to a mixer with just one CAT5e cable. The S-4000M is also compatible with designated PC/Mac software for more controllable parameters.

REAC Technology

The Roland Ethernet Audio Communication technology offers professional quality processing to your audio. The 24-bit/ 96kHz processing takes a high quality audio sample and then produces it with crisp clarity. REAC allows the Digital Snake’s signal to be split to a whole number of positions such as monitor, broadcast and recording. The whole processing of all the inputs and outputs can be sent down a single CAT5e cable, which stops excessive wiring and cluttering issues.
