Juan was born and raised in Buenos Aires, Argentina. He started teaching himself how to play guitar—his main instrument—as well as bass, keyboards and drums at the age of 9, before joining local bands and performing around the country. After studying sound engineering at the Universidad Nacional de Lanús, he worked as a live sound engineer and separately on a number of music productions in his home studio. Juan also trained as a luthier/guitar technician from an early age, repairing stringed instruments and all sorts of guitars with his father, using his surname Diaco as a brand.
In 2014 Juan moved to London, UK, to develop his skills and connections. His passion and commitment to music led him to working at guitar repair workshops around the capital city including Camden Town and Denmark Street where he repaired guitars for artists like Jarvis Cocker (Pulp), Michael Kiwanuka, Mumford & Sons, and King Krule among others. Simultaneously, he joined different bands as a guitarist and busked at various spots. Juan was hired to work as a Guitar Technician at Abbey Road Studios on recording sessions for Indie bands such as “Los Nuevos Monstruos” (2014) and “Conexionistas” (2015). During this period spent in the studios, Juan met Alex Wharton (Mastering Engineer) who became not just one of his best friends, but his biggest inspiration to start writing his own music.
