Teaching Machines is a Cardiff, Wales-based boutique audio hardware company founded by Frank Naughton and Mat Wigley. Naughton is a musician, engineer, and producer who also runs Ty Drwg, a recording studio in Cardiff, while Wigley contributes design and electronic music production experience. The company hand-builds analogue outboard and effects gear aimed at studio engineers, guitarists, and synthesists.

Their debut product, the Wellspring, is an analogue stereo spring reverb that pairs two 15-inch spring tanks with an analogue delay, filters, modulation, and a feedback path designed for deeper sonic shaping than a traditional spring unit. Their second release, the FuzzBillion, is a fully analogue distortion and tone-shaping pedal developed in collaboration with Grindle of Life Is Unfair Audio Devices; it uses eleven numerical selector wheels to navigate roughly ten billion possible distortion configurations, with both guitar and line-level I/O switching for use with synths and drum machines.

The brand has built a reputation in the boutique pedal and studio outboard scene for combining hands-on, recallable analogue control with hi-fi build quality, exhibiting at events like Bristronica and earning coverage in publications such as Sound on Sound and Tape Op.

Teaching Machines has 1 product cataloged on Equipboard, including Effects Processors.
