Jim Mullen is a Scottish jazz guitarist. His distinctive style, picking with his thumb rather than a plectrum, gives a rounded tone. He has played with Brian Auger's Oblivion Express,  Kokomo and  the Average White Band  and won a number of British music awards. He often favoured a telecaster but has also plays traditional archtop jazz guitars.

Mullen trivia: His playing featured on a 1990s advert where teenagers frantically thumbed through the Yellow Pages to find a French Polisher to repair a table damaged in a party before their parents returned from holiday.
