Wyvern Concerto 354
The Wyvern Concerto 354 is our top of the range three manual drawstop organ with an impressive, yet comfortable console.
A magnificent and inspiring instrument
Unashamedly this is very much a British organ built on samples from notable English cathedral organs. The third manual is voiced as a traditional English Choir Organ and a Positive is available on the Baroque specification.

ADDITIONAL SPECIFICATIONS
Choose between traditional wooden drawstops, WDS or optional full moving action KA drawstops, MDS.
In addition to the English stop list there are three alternative specifications: German Baroque, French Romantic. For the fourth specification, we can offer a Dutch or (optionally) a Theatre Specification (complete with tuned percussions) offering the organist truly versatile potential to register music from all periods and genres. These are neatly indicated by magnetic overlay panels, one for each alternative spec.
There is a generous provision of programmable general and department thumb and toe pistons. The large in-built audio system creates a spatial sound of cathedral quality.
CRAFTSMANSHIP
The elegance of the real oak consoles with solid oak slat roll tops give them a refined air of quality and there is a choice of light or dark oak or at extra cost a further range of different wood finishes. With an extensive list of options it is possible to build your organ to your own individual requirements… just ask us how.

“My sincere thanks for the exceptionally high standard of instrument and installation of the new Wyvern Concerto 354 at Plymouth Cathedral.
The console and large audio system is beautifully crafted and everything functions perfectly. The care and skill employed by Lyndon and Paul during the installation and voicing was very apparent and very appreciated.
Our paths first crossed in 1980, and I have lost count of the number of times Wyvern have supplied organs to churches, both in London and in the West Country over the past four decades where I have had some involvement, but I do clearly recall that each one has been of the best possible quality, backed up by superb customer service and after sales.
Naturally the most important consideration with any organ is how it sounds, and how things have improved in that regard over the last 42 years! The Concerto 354 is beyond excellent, giving a warm, authentic English sound that will fill the Cathedral with music for many years to come. My personal thanks to you and all the team at Wyvern.”
Robert Osmond, Organist & Director of Music: Plymouth Cathedral
