Philippe Dubreuille is a French-born luthier based in London who has built custom electric and bass guitars since the early 1980s. After growing up between Paris and Geneva, he began his craft by building a replacement for a lost instrument, then apprenticed in a Geneva repair shop before working at a Portuguese guitar factory and eventually settling in London. His workshop operates out of the Rock'nRoll Rescue shop on Parkway in Camden, with ties to Denmark Street, the historic heart of London's guitar trade.

Dubreuille specializes in one-off commissioned builds tailored to each client, producing electric guitars, basses, resonator/resophonic instruments, and amplifiers. His output is often associated with the "Doobie" line — an Anglicized nickname for his surname applied to a series of guitars, basses, and amps — alongside bespoke custom-shape and classic-bodied instruments.

His instruments have been commissioned and played by a range of rock and alternative artists, including Robert Smith of The Cure (an early patron), Joe Perry, Iggy Pop, Jeff Beck, Dave Stewart, Noel Gallagher, and Keziah Jones.
