JW Handcrafted Guitars operates from the historic Stationery Factory in Dalton, where owner Jack Waldheim combines 25 years of lutherie experience with a craftsman’s attention to detail. As a full-time instrument repairman and part-time luthier, Waldheim has built a reputation throughout Berkshire County for both expert guitar repair work and stunning custom guitar builds.

The shop handles the full spectrum of guitar services, from basic restrings and professional setups to advanced fretwork including fret leveling and complete refretting jobs. Waldheim specializes in “hot-rodding” instruments, working with musicians to upgrade electronics, install custom pickups, and modify guitars to meet specific performance needs. His expertise extends beyond guitars to mandolins, violins, banjos, and other stringed instruments.

What sets JW Handcrafted apart is Waldheim’s dual role as both guitar tech and builder. His custom boutique guitars showcase the same meticulous craftsmanship he brings to repair work. The shop also offers custom cables with a 20-year guarantee, professional pedalboard builds, and collaborates with on-site amplifier specialist Nick Winnard of Moddjobbs. As an authorized Fishman and WD Music dealer, the shop maintains quality parts for any repair or customization project.
