Seth Baccus Guitars is a small-batch electric guitar workshop founded by British luthier Seth Baccus, who built his craft working alongside Andy Manson before establishing his own brand. The shop produces a focused range of original designs, including the single-cutaway set-neck Nautilus, the Fullerton-inspired bolt-on Shoreline, the offset Argonaut, and the more progressive 22- and 24-fret Merkaba, alongside a Special Reserve line emphasising exotic tonewoods and fully bespoke custom orders.

The instruments are aimed at the boutique end of the market, with attention paid to wood selection, hand-finishing, and player-oriented appointments. Models from the range have picked up Gold Awards and Editors' Choice nods from publications including Guitarist and Guitar World, helping cement the brand's reputation among UK boutique builders. Notable players associated with the brand include Adam 'Nolly' Getgood, Alain Johannes, Kris Barras, Rikki Lee, and Jacky Bastek.
