An aspiration to inspire

Cosmic Amp Works® in Wageningen, The Netherlands, designs and builds custom handmade guitar amplifiers that employ simple but elegant tube-based circuitry, allowing the player to get inspired by the guitar’s true character and the magic that electron tubes add.
To the creative player, it matters if an instrument is designed and built with love, attention and eye for quality. That’s perhaps more obvious for an eye-catching guitar than for the amp that sits so inconspicuously behind you, but applies no less to the latter! A great amplifier likely brings greater benefits for your tone than a great guitar.
For an original hand-built amp that greatly enhances your tone and will inspire your playing… don’t look any further than Cosmic Amp Works®!
