Guitar Wharf

Guitar Wharf is a guitar repair and setup practice based in London, focused on helping musicians and collectors understand their instruments and get the best out of them.

Founded by guitar technician Riccardo Marchionni, Guitar Wharf combines hands-on repair and customisation work with, workshops and one-to-one sessions. The goal is simple: make instruments comfortable, reliable, and inspiring to play, while helping players develop a deeper understanding of how their guitars, basses, and stringed instruments actually work.

Guitar Wharf workshops are designed to be practical, accessible, and grounded in real-world experience — offering musicians the tools, vocabulary, and awareness needed to care for their instruments properly and make informed decisions over time.
