Even casual music fans recognize that Fender, Marshall, Peavey and handful of other brands are the dominant guitar amps used by rockers. But hardcore fans and great guitarists also know about the custom made amplifiers produced by Howard Alexander Dumble. He made them by special order for the likes of Eric Clapton, Carlos Santana, Stevie Ray Vaughan, Kenny Wayne Shepherd, Robben Ford, Eric Johnson, Kirk Hammett, David Lindley, Steve Lukather, John Mayer, Steve Vai, Joe Bonamassa and many, many more. Dumble's death was confirmed today via an Instagram post that read "It is with great sadness that we announce the passing of Howard. His work brought joy and inspiration to countless musicians and engineers. May he rest in peace."
