Cranky’s has been a cornerstone of Massachusetts guitar repair since 1980, when founder and chief technician established his one-man shop in Mansfield. With over four decades of hands-on experience, Cranky’s specializes in both tube amplifier service and comprehensive stringed instrument repair, handling everything from routine guitar setups to complex fretwork and headstock repairs.

The shop’s expertise extends to custom boutique guitar builds and vintage guitar work, with the technician having hand-crafted acoustic and electric instruments from scratch and established the repair department at Parker Guitars. His knowledge of vacuum tubes, pickups, and guitar wiring is considered industry-leading, having provided factory-authorized warranty repairs for major brands including Fender, Gibson, Marshall, Taylor, and Guild.

Beyond standard guitar repair services like pickup replacements, bridge work, and body routing, Cranky’s tackles specialized projects including Floyd Rose upgrades, custom wiring modifications, and soundboard straightening. The shop has trained repair technicians nationwide and pioneered a mentorship program teaching guitar and tube amp repair skills. With published pricing that competitors reference and a customer-focused approach emphasizing personalized service, Cranky’s has built its reputation on expertise and reliability.
