Koehn Concert Cedar

Warm and focused


The Red Cedar (Thuja plicata) mainly grows in the American North-West and in the West of Canada (British Columbia). It belongs to the family of Cypresses and with a height of 70 metres and a diameter of three to four metres it can be called a „tree-giant“. It doesn't have a very long history as tonewood for guitar tops. It was only in the 1960s that it was first discovered for that kind of use.

The wood is more porous and elastic than spruce, but also lighter. Its good balance between stiffness and weight combined with its loose structure makes cedar an interesting alternative to Spruce for making guitars.

The Concept

Model Cedar captivates the attention with its elegant, dark appearance, a quick response, a warm sound and a focused tone. It is powerful and has a lot of volume, without losing the sonic beauty of a traditional guitar.

I use special details in the construction to fully realise the possibilities of this wonderful tonewood. The solid top is jointed from two bookmatched halfs of solid Canadian Red Cedar (Thuja plicata) and reinforced with asymmetric fan-shaped bracing made of Spruce (Picea abies).

In combination with Rosewood back and ribs, this model offers many of the positive sound-features usually found in guitars with a Spruce top. The sound ist round, warm and yet clear and can be modulated easily.

I laminate the Rosewood ribs with Cypress or Pearwood (double rib) and the Mahogany neck has a carbon fibre rod. This construction allows for a long sustain and a good projection. Working out individual measurements that are ideal for the player, is part of my concept. By doing that, I can create an instrument that is particularly comfortable to play.

Model Cedar is suitable for guitarists who are looking for an instrument with a dark, full voice and a balanced, orchestral character.
