Stateline Instrument Repair has been serving musicians in the Illinois-Wisconsin stateline area since 1977, completing over 95,000 instrument repairs with a personal guarantee backing every job. As a long-standing member of the National Association of Professional Band Instrument Repair Technicians since 1978, this South Beloit shop has built its reputation on quality work for orchestra and school band instrument support, serving everyone from beginning students to professional players.

While primarily known for band instrument expertise, the shop also handles vintage guitar work for players seeking experienced craftsmanship on their classic instruments. The technicians understand that proper guitar setup and careful restoration requires the same precision and attention to detail that goes into professional brass and woodwind repair.

The shop operates by appointment to ensure each instrument receives adequate time and attention. This scheduling approach allows the repair team to properly assess each guitar or band instrument and provide accurate completion timelines. For musicians shipping instruments from a distance, advance arrangements help coordinate the repair process and set realistic expectations for turnaround times.
