Crimson Guitars is a British luthier workshop based in Dorset, England, founded by master builder Ben Crowe. Operating from a converted old dairy at Carters Barn Farm near Dorchester, the company hand-builds bespoke electric guitars, basses, and extended-range instruments, with customers able to specify custom inlays, hardware, non-standard tonewoods, and neck dimensions. Showcase master-build pieces such as The Nebula and The Complication have been used to demonstrate the shop's approach to ornate, one-off commissions.

Beyond instrument building, Crimson has built a parallel business around luthier education and tool-making. The workshop runs guitar-building courses ranging from short two-day classes to three-month programs, hosting hundreds of local and international students each year, and sells a line of purpose-designed luthier hand tools, hardware, timber, and kit guitars through its online shop. Ben Crowe's YouTube channel, which documents builds, repairs, and tool use, has grown a large following and is a significant part of how the brand reaches the wider guitar-making community.
