LSJ Music Company has been serving musicians in Delavan since 2015 as a comprehensive music shop with full-service repair capabilities. Owner and operator Lukas Janaky, a dedicated music enthusiast, established the business to provide Southeastern Wisconsin with professional guitar repair, instrument setup, and customization services all under one roof.

The shop’s repair techs handle everything from basic guitar setups and restrings to more complex fretwork and complete instrument overhauls. Beyond standard repair work, LSJ’s MOD Shop takes customization to another level, building custom guitars, amplifiers, and pedalboards tailored to individual player specifications. This luthier expertise combined with modern modification capabilities gives musicians access to both traditional instrument repair and contemporary custom builds.

Located in historic downtown Delavan, the full-service showroom carries trusted brands like Ernie Ball Music Man, Ibanez, Luna Guitars, and JHS Pedals. The guitar tech team works on all makes and models, bringing the same attention to detail whether performing routine maintenance or complex restoration work. LSJ Music Company also operates a professional recording studio and offers private lessons, making it a true one-stop destination for guitar repair and all musical needs.
