Dumble Amplifiers

Dumble Amplifiers was a guitar amplifier manufacturer founded in Santa Cruz, California in the late 1960s. In a one-man operation, Howard "Alexander" Dumble (June 1, 1944 – January 16, 2022) made each amp personally, often tailoring its design to suit the buyer's preferred tone and playing style. Dumble produced only a handful of amps per year—and just 300 in total—primarily for a clientele of well-known musicians, including Robben Ford, Carlos Santana, Larry Carlton, and Stevie Ray Vaughan. Dumble's amplifiers are among the rarest and most expensive boutique amplifiers on the used market, with the brand's flagship Overdrive Special fetching tens of thousands of dollars. Other models have sold for more. Joe Bonamassa put Dumble alongside Fender, Marshall, and Vox as one of the industry's "four quintessential guitar-amp tonalities".
