Hand-Built Tube Guitar Amps Made in the Netherlands

Who builds hand-wired tube guitar amps in the Netherlands?
Kool Amplification was founded in 2007 by amp designer and guitarist Aryjan Kool, who has been tweaking amplifiers and electric guitars since the early nineties. Kool amplifiers and cabinets have been part of numerous recordings and live rigs of Dutch acts, and guitarists all over the world have found them since.
Dutch design is at the heart of how the amps are made: beauty and functionality blended in every design, with old-world craftsmanship, state-of-the-art technology and carefully chosen components and materials.
What does hand-wired mean at Kool Amplification?
Every Kool amplifier is hand-wired, assembled and tested in the Netherlands, one at a time and without PCB shortcuts. There is no mass production: each amplifier is built to order in the same workshop.
