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.

Sontronics Sigma Active Ribbon Mic


The SIGMA is one of Sontronics' most popular microphones boating modern technology, vintage style and value for money. Inspired by the classic vocalists of the Swing era, Sontronics' thoughts drifted away to the simply unforgettable voices of Nat King Cole, Billie Holiday, Louis Armstrong and Ella Fitzgerald.

The SIGMA's specialty is to recreate the silky, rich tones that we heard from those old recordings, but without the pops and crackles. Punchy low and mid frequency responses combined with an ultra-smooth high frequency roll-off produce a very natural image, almost making the instrument or vocal sound like it is in the room with you!

The SIGMA is phantom powered and its output is actively balanced which means, unlike most transformer-based ribbon microphones, it does not suffer from impedance mismatching problems and low output sensitivity. In fact, it is as easy to use as any other Sontronics condenser microphone - just plug it into your preamp and play!

The Sontronics circuit design delivers some of the lowest self-noise figures of any ribbon microphone on the market and the aluminium ribbon element itself is less than 2 microns thick, all of which goes to make a very accurate and responsive microphone.

The unique shockmount system is extremely effective and allows the microphone to be placed close to the source with complete isolation from noise transmitted through the mic stand. The applications for the SIGMA mic are truly varied, but Broadcast, Vocal, Acoustic, Orchestral and Drums and Percussion are a few options you could consider.

Now Includes: EZ Drummer Lite:

EZdrummer Lite is the stripped down version of the multi-microphone drum-sampler EZdrummer. It is designed for musicians and producers in need of a compact, affordable, easy to handle plug-in without compromising sound quality or control.

The visualized drums in the interface combine auditioning of sounds and drumkit construction. The extensive drag and drop midi-library enables users to create a great drumtrack in less than five mouse-clicks. For more advanced handling, users can control microphone bleeding and levels between drums using the internal mixer. The mixer also allows stereo and multitrack routing into the host through one single plug-in, and thanks to the second generation Toontrack Percussive Compression (TPC), system requirements are kept to a minimum. The drums for EZdrummer Lite were recorded, produced and played by the best in the business at Avatar Studios in New York.
