At the moment I have two double basses. The instrument I use for most projects is a loan from the Dutch Musical Instruments Foundation (NMF). It was build by Harry Jansen in 1997, modeled after a bass by Vincenzo Panormo (± 1771). I have been playing this bass since Juli 2019, and I am very grateful since it has given me more opportunities to expand my technical and musical skills. Please see www.muziekinstrumentenfonds.nl for more information about the foundation.
My other bass has been in my possession since 2012, and was build by Jürgen Preyer in 2011. It is a beautiful, slim instrument, modeled after an Italian example.
I have a French bow build by Roger Lotte in ±1960, which works very well for chamber music.
For orchestral I music I mostly use an incredible bow build by August Rau in ±1930.
