Emiel van Egdom,
Guitarist, composer, arranger and swordmaster,
needs no introduction... Van Egdom, of international acclaim, who divides most of his time between Europe and the USA, is an old friend of Jan Knooren. They've been working together for many years on many, many projects and concert tours.
It's obvious that because of the quality of Mr. Knooren's work and their lifelong friendship van Egdom endorses Knooren Guitars which combined with van Egdom's talent, virtuosity and connections introduced the instruments to many internationally known musicians... He plays, amongst others, a prototype Knooren Strat, the model called "EVE". The guitars can be heard on many great CDs and concerttours of many jazz/rock and classical artists.
A classical nylon string electric/acoustic is in the design stage now.
Richard Ritterbeeks, bassplayer with former Dutch (9 piece) popgroup Volumia! which had several Top 5,10 and 20 hits in the Netherlands and Belgium.
Worked in France, Germany, Belgium, Singapore, Aruba, the "Kuip", the "Arena", together with the Residentie Orkest (Jaap van Zweden), Toots Thielemans etc..
When asked "why a 5 string Knooren bass?":
"Simply because it's a good instrument that is super playable.
Because it has a very tight low B with a total sound that is definable and can cut thru a 9 piece band.
Everything a bass needs!!!"
