Expert Guitar & Bass Repairs – Setup · Maintenance · Restoration
At Belforti, every instrument receives the same expert care, from vintage treasures to beginner guitars. We use the same high-quality materials and processes as in our own production. If you need a specific service beyond our listed options, feel free to reach out—we’re here to help.
Belforti Instruments operates two professional guitar workshops in the Paris region: one in Rueil-Malmaison (Hauts-de-Seine, west of Paris) and one in Montrouge (south of Paris), just minutes from the Music Live rehearsal studios. We proudly offer high-end guitar repair, setup, fretwork, and customization for electric guitar and bass players seeking expert craftsmanship.
We are currently the only dedicated guitar luthiers serving the south of Paris and the Hauts-de-Seine (92), making us a trusted reference for musicians across the greater Paris area. Whether you need a complete fret leveling, action adjustment, nut replacement, or electronic upgrades, our guitar repair services are available by appointment to ensure precision and care.
We also provide full electric guitar restoration and renovation — perfect for vintage models or instruments in need of serious structural attention.
If you're searching for a guitar luthier in south Paris, a guitar repair shop in 92, or a setup specialist near Music Live Montrouge, Belforti Instruments offers unmatched expertise and personalized service.
CHECK OUT OUR SETUP, MAINTENANCE & REPAIR SERVICES BELOW
We encourage you to read our detailed article on what to expect from a guitar or bass setup — it’s a valuable resource to understand what a setup can improve, what it can’t, and how to communicate your needs for the best possible results.


After booking, we’ll meet at your chosen location (Montrouge or Rueil-Malmaison). A full diagnosis will be done in person, as issues can’t always be assessed remotely. Your instrument details will be recorded, work assigned, and a pickup date set. For pricing and terms, see our pages below.
