Jim Deacon was a budget guitar brand associated with SMIRA (the Scottish Musical Instrument Retailers Association), a cooperative of independent UK music retailers that sourced instruments directly from factories in the Far East during the 1990s. The brand name was used across a catalogue of affordable copies of popular American designs, giving beginner and intermediate players an inexpensive entry point into recognizable body shapes.

The product range covered Stratocaster- and Telecaster-style electrics, Les Paul-style solidbodies, hollowbody archtops, dreadnought acoustics, and electric basses. Because instruments were sourced from multiple overseas factories across different production runs, build quality varied from model to model and year to year, with players often comparing the electrics to entry-level Squier Affinity-tier instruments rather than more premium copy brands.

Jim Deacon guitars are no longer in active production and the brand is primarily encountered on the UK secondhand market through retailers like Reverb and Gumtree. They remain a recognizable name among British players who came up in the '90s looking for a cheap first guitar.

Jim Deacon has 4 products cataloged on Equipboard, including Solid Body Electric Guitars, Steel-string Acoustic Guitars, and Acoustic-Electric Guitars.
