The Filter Fuzz is Hiwatt Custom Shop's tone-obsessed take on your favorite classic '60s Fuzz. Designed through collaboration between two Hiwatt Custom Shop heavyweights, the Filter Fuzz aims to deliver old-school analog sensibility with an expanded gain and frequency range. A historic nod to the sounds of '69 produced on the Grand Funk album, this "free love" moment between a Musicraft Messenger guitar and a Heathkit Fuzz has been the inspiration for our filters section.
