In 1982 I set up my workshop together with master luthier Federico Löwenberger (Alessandro's father), and we had been working together for more than 30 years at the time of his death in 2013. It may sound funny, but we explored many aspects of luthiery alongside our production of historically informed instruments and bows, with the same approach, we also made double basses and electric guitars, and even nowadays I really like setting them up properly! Through the years we had friends come to work with Federico and me, among whom Silvio Ferretti, Gianmaria Assandri, Alessandro Lowenberger and Paola Parodi (my wife) who helped me so much in recording original bows. And Also Valentina Montanucci, Chiara Segaliari, Maurizio Vella, Marie Eve Geeraert who co-worked with us.
