Trusted by the Pros. Proven on the Stage.
Since I established The Guitar Workshop in 2008, I have been a silent partner behind the best tones in the region. My bench is where decades of technical precision meet the demands of the modern stage. I am proud to announce The 2026 Artist Roster - a collective of musicians who trust only The Guitar Workshop to keep their instruments performing at the highest level.
The Guitar Workshop is Chicagoland's premier guitar repair and custom guitar shop. Owned and operated by myself, Luthier, Mario Percoco. By working with many top musicians I have developed setup, repair and customizing techniques to meet the very high quality demands for studio and stage instruments. Even if you're not a pro, you and your instrument will be treated like one. Specializing in acoustic and electric guitar, bass, banjo, mandolin, ukulele, dulcimer and other stringed instruments.

My Guarantee
I guarantee all of my work. My ultimate goal is for you to be completely satisfied with your experience here, and I will always work with you on making sure that happens. I encourage you to inspect and test your instrument here before you leave. After you get home and put some playing time on your instrument, if you feel anything is off, I want to be the first to know. NEVER hesitate to call, as I would be happy to make any adjustments to suit your needs. I don't just fix guitars; I optimize them. If it isn't right. I'll make it right. Period.
