For decades, Dumble has been the most mythical name in guitar amplification. Now, four years after the death of its founder, the brand is officially taking orders again. In early October 2026, Guitar World reported that the Overdrive Special, along with the Tweedle Dee and MegaPLX, can be ordered directly from Dumble.
Who Was Alexander Dumble?
Howard Alexander Dumble built amplifiers by hand in California, in tiny numbers, often for specific players. He rarely sold to the public, kept his circuits secret and was known to cover his boards in epoxy so they couldn’t be copied. That mystery, combined with the sound, turned his amps into legends.
His amps were played by Stevie Ray Vaughan, John Mayer, Joe Bonamassa, Keith Urban and Lowell George, among others. Original Dumbles rarely change hands, and when they do, prices run into six figures.
Alexander Dumble died in 2022.
Who Is Making Them Now?
The brand is now run by the Dumble Preservation Society, a group made up of Dumble’s closest friends and colleagues. The Dumble website relaunched in late 2024, and the Society made a public appearance at NAMM in January 2025 to explain its plans.
What You Can Order
Three models are listed:
- Overdrive Special, the most famous Dumble circuit, available as a head and a combo
- Tweedle Dee
- MegaPLX
These are made to order. There’s no standard production run, no published price list and no dealer network: interested players contact Dumble directly through its website.
A Dumble for the Rest of Us?
For most players, a hand-built Dumble will stay out of reach. But there’s another way in. A MegaPLX plugin has been released in collaboration with TONE3000, based on Neural Amp Modeler (NAM) captures of one of the rarest Dumble designs. According to the reporting, only three original MegaPLX amps were ever made.
It’s another example of how modelling is opening up gear that used to be unobtainable. We saw the same trend at Guitar Summit 2026, where NAM captures and touchscreen modellers were everywhere.
Why the “Dumble Sound” Matters
Players describe Dumble amps as having a smooth, vocal overdrive, with a touch-sensitive response that cleans up beautifully when you play softly. A whole category of “Dumble-style” amps and overdrive pedals exists because of it.
Whatever amp you play through, the sound starts with the guitar. Fresh strings, clean pots and properly set pickup heights make a bigger difference than most players expect. Our guide to 250K vs 500K pots explains one of the less obvious pieces of the puzzle.
Our Take
It’s good to see the Dumble name looked after by people who knew the man and his work, rather than turned into a mass-produced brand. Made-to-order amps keep the spirit of the original, and the plugin route lets the rest of us hear what the fuss is about.
