DUMBLE PRESERVATION SOCIETY, LLC, CALIFORNIA, USA

Crafted for those who demand tone, power, and the heritage of true analog sound in every performance

The Dumble Preservation Society was born from a devotion to Howard "Alexander" Dumble and his pursuit of "Musical Sound".

True to our name, we preserve his legacy by maintaining original "Dumble" built amplifiers with NOS parts selected and acquired by Alexander himself, and building limited edition amplifiers to Alexanders exacting standards.

Everything we produce is guided by our extensive archive of original Dumble designs, schematics, letters and photographs, lovingly preserved and cataloged by Alexander himself.

Built for tone

Each amplifier blends hand-wired precision with road-ready construction and vintage flair, delivering unmatched sonic character and reliability.

We believe every amplifier should carry the weight of history and the promise of tomorrow—built for musicians who never compromise.

Our amplifiers are forged at the intersection of tradition and innovation, capturing the soul of Dumble sound for a new generation.
