Aldrich was first introduced to the guitar at age 11 when his sister Jennifer introduced him to the playing of Jeff Beck. Aldrich's first guitar was a Les Paul model and came from Sears. Aldrich auditioned for Kiss. He did not get the gig but as a result of the audition he met Gene Simmons and he and Gene are friends to this day. Aldrich was also once a highly sought after guitar teacher, at one point he was teaching over 70 students a week. In early 2014 Aldrich joined the critically acclaimed production show "Raiding the Rock Vault" at the New Tropicana Hotel and Casino where he performed six shows a week with other Rock'n Roll greats like Robin McAuley (formerly Survivor, MSG), John Payne (Asia), Howard Leese (Bad Company, Heart), Paul Shortino (Quiet Riot), Andrew Freeman (Offspring) and more. In late January 2016, it was announced that Aldrich would be replacing Richard Fortus as guitarist in The Dead Daisies, as Fortus will be participating in the Guns N' Roses reunion. As of late January 2016 Aldrich was in Nashville with The Dead Daisies, working on a followup album to 2015's Revolución. As a member of The Dead Daisies Aldrich is being reunited with bassist Marco Mendoza; the two previously performed together in Whitesnake.
Aldrich was previously endorsed by Jackson Guitars. He used their Dinky and Soloistsuperstrats as well as his own signature model which has bridge and neck position humbucking pickups were "Full-shred" pickups which Seymour Duncan specially wired. Presently, California-based Suhr Guitars offers Aldrich signature humbucking pickups, which are also found on their superstrat-style 24-Fret Moderns. He plays various Gibson Les Pauls and Fender Stratocasters through Suhr/ Cameron hot-rodded Marshall JMPs and Vintage Modern amps. Aldrich sums up his philosophy of playing this way, "I'm not one of those guys that follows whatever is trendy. I'd rather do what I do best and do it to the best of my ability."
