Bruce Egnater may not be that well known in the UK, but his reputation as one of the worlds top amp designers is assured. With a stellar career spanning 35 years, Bruces customers have included some of the biggest names in rock and metal. These include Dimebag Darrell, Nuno Bettencourt and Steve Vai, as well as consultancies with Rocktron and Randall (who license Bruces modular concept). Based in Berkeley, Michigan, Egnater has always run his own custom shop, but is presently focused on a groundbreaking series of Chinese-built amps that have taken most of the world by storm in the past couple of years. Recently we looked at the Rebel 30 combo, but now its the turn of the small but perfectly formed Tweaker.
