Dumble guitar amps – and tube amps that were modded by the late amp technician – are some of the most elusive, most expensive pieces of guitar gear that you could ever hope to get your hands on.
To buy a stock Dumble, you’ll have to be rather lucky (and have very deep pockets) as they don’t crop up very often, and when they do, they have eye-watering price tags. During the amp designer’s heyday, he also modded Fenders, Marshalls and more. These mods, too, came at a price.
