Martinus Geelen Trumpets

Handmade in the Netherlands

The workshop of MG Trumpets / Bec’s Brassworks is located in Wijk bij Duurstede, close to "the green heart" of the Netherlands. In the workshop we work with the two of us: Mark Geelen and Becci Carr. Mark is an instrument builder and professional trumpet player. He plays with several ensembles like the Dutch Bach Society (see and as a guest player with the Orchestra of the 18th century. Becci (bec's brassworks) has had an interesting carreer as a designer and seamstress working for Ted Baker and Jack Wills. Then she decided to learn goldsmithing. Becci has magic hands and a good eye for detail. Whenever there is time (in between looking after our two little boys) Becci assists with repairs, maintenance and work on historic and modern instruments.

In house part production

This little video below shows what kind of work goes into making in house parts. This is the making of some simple but important natural trumpet components. For small parts we often use the biggest machines. Not what one would expect. Every little step has to be of high quality using decent machinery because part making is a chain of events that need to end up in the best and nicest fitting parts to produce the best and nicest instruments ;).
