Bludotone Amp Works is a small boutique amplifier builder based in Littleton, Colorado, founded by Brandon Montgomery in 2004. The company is focused on hand-wired, Dumble-style guitar amplifiers, with each unit built start-to-finish by a single person using premium components. Montgomery has also spent years servicing original vintage D-style amplifiers, and Bludotone is widely regarded in the boutique community as one of the leading builders working in this tradition.

The brand's flagship is the Bludo-Drive, a two-channel Overdrive Special–inspired head that has been in continuous production since 2007. The broader lineup includes the Ojai, Hi-Plains Drifter, Bludoland, Mordecai, Joyeuse, South Saturn Delta, and a smaller Bludo-Drive Mini, along with a line of matching 1×12, 2×12, and 4×12 speaker cabinets. Bludotone also produces outboard units such as the Loop-A-Lator.

Players associated with Bludotone amps include Carlos Santana, Larry Carlton, Robben Ford, Sonny Landreth, and Jon Herington. The amps are also represented in digital form, with Fractal Audio modeling the Bludotone Ojai as the "Bludojai" in its Axe-Fx platform.

Bludotone has 4 products cataloged on Equipboard, including Guitar Amplifier Heads and Guitar Preamps. Their gear is featured by 4 artists, with the strongest followings in Rock and Jazz. Notable users include Mark Tremonti, Carlos Santana, and Larry Carlton.
