Heinrich Nusko - Model with cedar soundboard:
On the CDs La Guitarra Poética, Ornamenten and Retratos, Duolisme play hand-built guitars by the Austrian guitar builder Heinrich Nusko. In combination with D’addario and Savarez strings, the clear transparent but warm sound is brought out well in these instruments. During concerts that require amplification, the Nusko guitars are provided with a Fishman microphone – with bridge pickup.
In combination with the speakers of Jan Verweij, the authentic typical cedar sounds remain as true as possible.
A completely faithful reproduction is impossible of course!
Peter about Frank's instrument: “Frank's instrument is a real gem. With a gentle tone, clear and transparent. A real find, which perfectly suits his way of playing”.
Frank about Peter's instrument: “Peter's instrument sounds grandiose. Warm tone and great projection. Combined with his way of playing, a perfect unit”.
