Made with the same premium components as the rest of Fjord Fuzz's line, the Berserk is a rich, purring fuzz that also cleans up nicely at lower volumes. With two Space Echo-style preamps wired in series, it can also boost other pedals in your signal chain or your amp. Open up the brand's characteristically slim and custom enclosure, and you'll have access to a few more controls, like an impedance adjustment, transistor bias, and LED brightness.
