"Die Gizouki ist nicht nur ästhetisch gelungen, sondern besitzt einen so großartigen Klang, dass einem das Wasser im Munde (oder in der Ohrmuschel?) zusammenläuft." Sebastian Barwinek über seine Dreizehnter - Gizouki
“Without doubt, it is the best bouzouki I have ever played and I have played alot over the years. I talked with Heiner about what I wanted and we agreed on the wood, what type of response it would give and what action I wanted. The instrument he made for me is exactly what I wanted. The pick-up is a joy to use, 20 second sound-check!!! Very highly recommended!”
