Antonio "Tunico" D'Andretta graduated in Computer Networks and a robotics course, and worked with technology and electronics for 15 years. But he then made his hobby of customizing guitars and basses into a profession. He started the luthiery course at B&H Escola de Luthieria in 2015. In September of the same year, he combined his experience in electronics and his passion for musical instruments and opened Dandretta. He was joined in 2016 by Diego Freixedelo - who since 2010 had been making Freixedelo custom instruments before becoming a partner in Dandretta.
